You can do this easily with the Client C++ APIs, where the client can define its resources in a similar structure to the one defined in the LWM2M specification. + +This quick guide will explain how you can create and configure these resources using the C++ API. + +## How to create and configure Objects + +The M2MObject class is derived from the M2MBase class, so all the public methods can be used from the M2MObject and its derived classes. + +### Creating OMA-defined Objects + +#### Device Object + +There is a direct API in the M2MInterfaceFactory class to create a Device Object: + +`static M2MDevice *create_device();` + +Because there can be only one instance of M2MDevice, it is a static class and you can delete it as follows: + +`M2MDevice::delete_instance();` + +Check the M2MDevice class documentation to see how to configure the device object, as well as how to create appropriate Resources and assign values to them. + +#### Security Object + +There is a direct API in the M2MInterfaceFactory class to create a Security Object: + +`static M2MSecurity *create_security(M2MSecurity::ServerType server_type);` + +You can create a Bootstrap or normal mbed Device Server by passing the appropriate `enum` value. + +Check the M2MSecurity class documentation to see how to configure the security object, as well as how to create appropriate Resources and assign values to them. + +#### Creating a custom Object + +As per the OMA LWM2M specification, the client must have defined Objects, under which it can create Object Instances. You can create an M2MObject using this API from the M2MInterfaceFactory class: + +`static M2MObject *create_object(const String &name);` + +You need to pass the name of the Object that you would like to create (for example `Test`); this will create an object with that name in mbed DS. + +#### Configuring the Object + +Once you have created an Object (whether OMA-specific or custom), you can configure various parameters in that object so that they can be controlled or modified to affect communication with mbed DS. + +Here, we discuss a few of the most important parameters, which you must configure properly to work with the objects. + +##### Setting Operation Mode + +You can set the operation mode of the objects so that they can handle `GET`, `PUT`, `POST`, `DELETE` or a combination of these requests coming from mbed DS. + +The API that sets the operation mode (present in the M2MBase class) is: + +`virtual void set_operation(M2MBase::Operation operation);` + +##### Setting Observable Mode + +You can set the object to be an observing resource. You can set the observable mode using the following API: + +`virtual void set_observable(bool observable);` + +##### Setting CoAP content type + +Currently, the only available content type is the OMA TLV type. The OMA TLV type works only for objects with a numeric value. For example, if you are creating a custom object it must be of a numeric type like `100`; only then the CoAP TLV type will work for the custom object. + +If you want your object to support the TLV type, set the object's CoAP content type as `99`: + +`virtual void set_coap_content_type(const uint8_t content_type);` + +Later we will introduce support for the JSON content types. + +## How to create and configure Object Instances + +The M2MObjectInstance class is derived from the M2MBase class, so all the public methods from M2MObjectInstance and its derived classes can be used. + +### Creating OMA defined ObjectInstance + +#### Device ObjectInstance + +Because there can only be one instance for the Device Object, the ObjectInstance is automatically created when creating an M2MDevice Object. + +#### Security ObjectInstance + +Because there can only be one instance for the Device Object, the Object Instance is automatically created when creating an M2MDevice Object based on a selected server type. + +#### Creating custom object instances + +As per the OMA LWM2M specification, the client must have created Object Instances under Objects, which will eventually contain Resources. + +You can create an M2M Object Instance using this API from the M2MObject class: + +`M2MObject::create_object_instance(uint16_t instance_id);` + +You can pass an Object Instance ID to create appropriate Object Instances. Normally, Object Instances will start from `0` and increment. So the Object Instance structure on the mbed DS side would look like this: + +`Object/Object Instance ID` + +You need to pass the name of the Object Instance ID that you would like to create (for example `0`); this will create an object `/Test/0` in mbed DS. + +### Configuring the Object Instance + +When you have created an Object Instance (whether OMA-specific or custom), you can configure various parameters in that object so that they can be controlled or modified to affect communication with mbed DS. + +Here, we present a few of the most important parameters that you must configure properly to work with the object instances. + +#### Setting operation mode + +You can set the operation mode of the Object Instances so that they can handle `GET`, `PUT`, `POST`, `DELETE` or a combination of these requests coming from mbed DS. + +The API that you can use to set the operation mode (present in the M2MBase class) is: + +`virtual void set_operation(M2MBase::Operation operation);` + +#### Setting observable mode + +You can set the object to be an observing resource. + +You can set the observable mode using the following API: + +`virtual void set_observable(bool observable);` + +#### Setting CoAP content type + +Currently, the only available content type is the OMA TLV type.

You can create the required Resource and set values based on their data types. + +- For Resources that take `string` values: + +`M2MResource* create_resource(DeviceResource resource, const String &value);` + +- For Resources that take `integer` values: + +`M2MResource* create_resource(DeviceResource resource, uint32_t value);` + +- There are a few resources that can have multiple instances. To create these resources, use these APIs: + +`M2MResourceInstance* create_resource_instance(DeviceResource resource, uint32_t value,uint16_t instance_id);` + +Where `instance_id` is the Resource Instance ID, for example `/3/0/11/0`. + +Check the M2MDevice API documentation to find which enums are supported for `integer` or `string` value types. + +There are other APIs in the M2MDevice class that you can use to set, remove and modify new values for the resources. + +#### Security Object Resources + +There are direct APIs to create and set values for the Security Resources, based on their data types. + +Most of the mandatory resources are created automatically when you create an M2MSecurity object. You can set their values using the following APIs: + +- For resources that take `integer` values: + +`bool set_resource_value(SecurityResource resource,uint32_t value);` + +- For resources that take `string` values: + +`bool set_resource_value(SecurityResource resource,const String &value);` + +- For resources that take binary values, like setting public keys and certificates: + +`bool set_resource_value(SecurityResource resource,onst uint8_t *value,const uint16_t length);` + +- You can create and set values for Resources that are not mandatory, and which take an `integer` value, using this API: + +`M2MResource* create_resource(SecurityResource resource, uint32_t value);` + +Check the M2MSecurity API documentation to find which enums are supported for `integer`, `string` or `uint8_t*` value types. + +There are more APIs in the M2MSecurity class that you can use to set, remove and modify Resource values. + +#### Creating custom Resources + +As per the OMA LWM2M specification, the client must have Resources under Object Instances which belong to Objects. + +You can create different types of Resources or Resource Instances. + +There are two types of Resources: + +- **M2MResource**: a resource with a unique instance, for example `/Test/0/Resource`. + +- **M2MResourceInstance**: a resource with multiple instances, for example `/Test/0/Resource/0`, `/Test/0/Resource/1`. + +Apart from these two types, you can create two types of Resource and Resource Instances: + +- Static: Resource and Resource Instances whose value does not change over time. +- Dynamic: Resource and Resource Instances whose value can change.

+# mbed Client API
+
+## Introduction
+
+mbed Client is an OS-agnostic embedded software library that provides the means to connect and manage constrained embedded devices to web applications through the mbed Device Server (mbed DS).
+
+The mbed Device Client API allows mbed OS developers to create applications with LWM2M features. These features are described in the [Lightweight Machine to Machine Technical Specification](http://technical.openmobilealliance.org/Technical/technical-information/release-program/current-releases/oma-lightweightm2m-v1-0); they include high level APIs to manage devices on mbed DS, securely communicate with internet services over the industry standard TLS/DTLS, and fully control the endpoint and application logic.
+
+The API is written in C++ to allow quick application development.
+
+## mbed Client interfaces
+
+There are three interfaces between mbed DS and mbed Client:
+
+- Client registration and deregistration
+- Device management and service enablement
+- Information reporting
+
+The API provides an interface to define the application endpoint information. This information will be delivered to mbed DS during the registration operation (explained below).
+
+To create an interface for your endpoint:
+
+```
+#include "mbed-client/m2minterfacefactory.h"
+#include "mbed-client/m2minterface.h"
+
+M2MInterface* interface = M2MInterfaceFactory::create_interface(*this,
+ "mbed-endpoint",
+ "test",
+ 3600,
+ 5684,
+ "",
+ M2MInterface::UDP,
+ M2MInterface::LwIP_IPv4,
+ "");
+```
+
+When you have created the interface, you can proceed to execute operations.
+
+### Client Registration Interface
+
+The client uses the Client Registration Interface to register with mbed DS, update registration and deregister.
+
+Currently, only one-to-one client-server registration is supported. One-to-many client-server registrations will be supported in an upcoming release.
+
+The Client Registration Interface includes multiple sub-features. Currently supported:
+
+- Register
+- Update
+- Deregister
+
+### The Register feature
+
+This API enables the client registration functionality.
+
+When registering, the client:
+
+* Performs the **Register** operation and provides parameters that mbed DS requires to register the client (for example End Point Name).
+
+* Maintains the registration and session (for example Lifetime, Queue Mode).
+
+* Provides information on the Objects the client supports and existing Object Instances in the client.
+
+#### Registering your client
+
+To provide information to mbed DS and issue the register command:
+
+First you need to create an mbed DS object. This object contains information about mbed DS, such as its address and security mode.
+
+```
+#include "mbed-client/m2msecurity.h"
+ M2MSecurity *security = M2MInterfaceFactory::create_security(M2MSecurity::M2MServer);
+ if(security) {
+ security->set_resource_value(M2MSecurity::M2MServerUri, LWM2M_SERVER_ADDRESS);
+ security->set_resource_value(M2MSecurity::BootstrapServer, 0);
+ security->set_resource_value(M2MSecurity::SecurityMode, M2MSecurity::NoSecurity);
+ }
+```
+
+**Note**: This API supports both non-secure and secure mode operations. For secure mode, you will also need to provide certificate, private key and server public key through the API.
+
+Create a secure mode operation as follows:
+
+```
+#include "mbed-client/m2msecurity.h"
+ M2MSecurity *security = M2MInterfaceFactory::create_security(M2MSecurity::M2MServer);
+ if(security) {
+ security->set_resource_value(M2MSecurity::M2MServerUri, LWM2M_SERVER_ADDRESS);
+ security->set_resource_value(M2MSecurity::BootstrapServer, 0);
+ security->set_resource_value(M2MSecurity::SecurityMode, M2MSecurity::Certificate);
+ security->set_resource_value(M2MSecurity::ServerPublicKey,<SERVER_CERT>,sizeof(<SERVER_CERT>));
+ security->set_resource_value(M2MSecurity::PublicKey,<CERT>,sizeof(<CERT>));
+ security->set_resource_value(M2MSecurity::Secretkey,<KEY>,sizeof(<KEY>));
+ }
+```
+
+Next, you need to register all the resources that you would like to monitor or follow via mbed DS. To do this, create the resource objects and pass them to the Register API for registration purposes.
+
+For example, if you want to register your OMA LWM2M based Device object, you need to create the object and set the values for mandatory resources as follows:
+
+```
+#include "mbed-client/m2mdevice.h"
+M2MDevice *device = M2MInterfaceFactory::create_device();
+if(device) {
+ device->create_resource(M2MDevice::Manufacturer,MANUFACTURER);
+ device->create_resource(M2MDevice::DeviceType,TYPE);
+ device->create_resource(M2MDevice::ModelNumber,MODEL_NUMBER);
+ device->create_resource(M2MDevice::SerialNumber,SERIAL_NUMBER);
+ }
+```
+
+**Note:** You can register other resources, including custom resources. Please check the API documentation for a detailed description of the M2MObject, M2MObjectInstance and M2MResource classes.
+
+You have the registration server object and resources that you want to register. Now, you need to call the register API and pass the following objects as parameters:
+
+```
+M2MInterface::register_object(M2MSecurity* register_object, M2MObjectList object_list);
+```
+
+**Success or failure callback**
+
+Because this is an asynchronous operation, you will receive the result of this operation through a callback defined in `m2minterfaceobserver.h` in your application.
+
+If the register operation is successful and the client can register all your resources to mbed DS, your application will receive the following callback:
+
+```
+void object_registered(M2MSecurity *server_object, const M2MServer& server)
+```
+
+The `M2MSecurity *server_object` specifies to which mbed DS instance the client has just registered and `M2MServer &server` contains the data related to mbed DS, including the Short ServerID and the client registration period.
+
+If the registration operation fails for some reason, you will receive the following callback:
+
+```
+void error(M2MInterface::Error error)
+```
+
+You will get more information about the error from the `error` parameter passed with the callback; use it to fix the source of the error.
+
+### Update
+
+Periodically, or in response to events within the client or as initiated by mbed DS, the client updates its registration information with mbed DS. It sends an **Update** operation to mbed DS.
+
+To update your registration:
+
+```
+M2MInterface::update_registration(M2MSecurity* security_object, const uint32_t lifetime)
+```
+
+Normally, the enabler will update the registration automatically, but if you want to renew the registration before that, you can use this API.
+
+**Success or failure callback**
+
+If the update operation is successful, your application will receive the following callback:
+
+```
+void registration_updated(M2MSecurity *const M2MServer& server)
+```
+
+The `M2MSecurity *server_object` specifies to which mbed DS instance the client has just updated the registration and `M2MServer &server` contains the data related to mbed DS, including the Short ServerID and the client registration period.
+
+If the update operation fails for some reason, you will receive the following callback:
+
+```
+void error(M2MInterface::Error error)
+```
+
+### Deregister
+
+The client can deregister from mbed DS when it no longer requires access to the server. When mbed DS receives the **Deregister** message it removes the device's registration information from its database. When the client needs mbed DS again, it will have to register again.
+
+To deregister your endpoint client:
+
+If the endpoint has multiple server registrations, you need to provide the `server_object` of the server where you would like to deregister your endpoint. Otherwise, if there is only one registration, you can pass `NULL` and the client will deregister the default registration.
+
+```
+M2MInterface::unregister_object(M2MSecurity *object);
+```
+
+**Success or failure callback**
+
+Because this is an asynchronous operation, you will receive the result of this operation through a callback defined in `m2minterfaceobserver.h` in your application.
+
+If the client is successfully deregistered from mbed DS, your application will receive the following callback:
+
+```
+void object_unregistered(M2MSecurity *server_object)
+```
+
+The `M2MSecurity *server_object` specifies from which mbed DS instance the client has just deregistered.
+
+If the deregistration operation fails for some reason, you will receive the following callback:
+
+```
+void error(M2MInterface::Error error)
+```
+
+You will get more information about the error from the `error` parameter passed with the callback; use it to fix the source of the problem.
+
+### Device Management and Service Enabler Interface
+
+mbed DS uses the Device Management and Service Enabler Interface to access Object Instances and Resources available on the client. The interface provides this access through the following operations:
+
+- **Create**
+- **Delete**
+- **Read**
+- **Write**
+- **Execute**
+- **Write Attributes**
+
+Currently, support for the Create and Delete actions is limited to Object Instances.
+
+The Device Management and Service Enabler Interface supports the following data types:
+
+- Text - for Resources.
+- TLV - for Object and Object Instances.
+
+### Read
+
+The Client API allows setting values to Resources, an array of Resource Instances, an Object Instance or all the Object Instances of an Object (TLV format supported). mbed DS can then read these values using the **Read** operation.
+
+**Creating Resources**
+
+There are two types of resources you can create:
+
+- Static: you set the value of the resource once and it does not change during the course of operations.
+- Dynamic: the value is expected to change during the course of operations. Therefore, the value is fetched from setter APIs every time the server requests a `GET` operation.
+
+Here is an example of creating a custom static Resource:
+
+```
+#include "mbed-client/m2mobject.h"
+#include "mbed-client/m2mobjectinstance.h"
+#include "mbed-client/m2mresource.h"
+_object = M2MInterfaceFactory::create_object("Test");
+if(_object) {
+ M2MObjectInstance* inst = _object->create_object_instance();
+ if(inst) {
+ inst->create_static_resource("S",
+ "ResourceTest",
+ STATIC_VALUE,
+ sizeof(STATIC_VALUE)-1);
+```
+
+And here is an example of creating a custom dynamic Resource:
+
+```
+#include "mbed-client/m2mobject.h"
+#include "mbed-client/m2mobjectinstance.h"
+#include "mbed-client/m2mresource.h"
+_object = M2MInterfaceFactory::create_object("Test");
+if(_object) {
+ M2MObjectInstance* inst = _object->create_object_instance();
+ if(inst) {
+ M2MResource* res = inst->create_dynamic_resource("D","ResourceTest",true);
+ char buffer[20];
+ int size = sprintf(buffer,"%d",_value);
+ res->set_operation(M2MBase::GET_PUT_ALLOWED);
+ res->set_value((const uint8_t*)buffer,
+ (const uint32_t)size);
+```
+
+For more information on different resource functionalities, please check the API documentation for the M2MObject, M2MObjectInstance and M2MResource classes.
+
+### Write
+
+The **Write** operation is used to overwrite the value of a Resource, an array of Resource Instances or multiple Resources from an Object Instance.
+
+Whenever there is a valid `PUT` operation for any of the resources, the application will receive a callback:
+
+```
+void value_updated(M2MBase *base, M2MBase::BaseType type)
+```
+
+Where `M2MBase` is the object whose value has been updated and `M2MBase::BaseType` is the object type.
+
+### Write Attributes
+
+Any readable Resource can have attributes that are considered during the **Observe** operation (explained below). The following attributes are used:
+
+- Minimum Period (pmin)
+- Maximum Period (pmax)
+- Greater Than (gt)
+- Less Than (lt)
+- Step (st)
+
+mbed DS sets the endpoint attribute values that are used to determine when the endpoint sends the Resource value to the server.
+
+Check the LWM2M specification for details of all the possible **Write Attributes** defined for different types of Objects and Resources.
+
+### Execute
+
+mbed DS uses the **Execute** operation to perform an action. This operation can only be performed on individual Resources.
+
+**Note:** The client **must** return an error when the **Execute** operation is received for Object Instances or Resource Instances.
+
+Here is an implementation example for the **Execute** operation:
+
+```
+#include "mbed-client/m2mobject.h"
+#include "mbed-client/m2mobjectinstance.h"
+#include "mbed-client/m2mresource.h"
+
+ void M2MLWClient::execute_function(void */*argument*/) {
+ }
+
+_object = M2MInterfaceFactory::create_object("Test");
+if(_object) {
+ M2MObjectInstance* inst = _object->create_object_instance();
+ if(inst) {
+ M2MResource* res = inst->create_dynamic_resource("D","ResourceTest",true);
+ char buffer[20];
+ int size = sprintf(buffer,"%d",_value);
+ res->set_operation(M2MBase::GET_PUT_POST_ALLOWED);
+ res->set_value((const uint8_t*)buffer,
+ (const uint32_t)size);
+ res->set_execute_function(execute_callback(this,&M2MLWClient::execute_function));
+```
+
+When the client receives the `POST` request for Execute from mbed DS for this resource, this function will be called and executed.
+
+### Information Reporting Interface
+
+mbed DS uses the Information Reporting Interface to observe any changes in a registered Resource on the client, receiving notifications when new values are available.
+
+The interface supports the following sub-features:
+
+- Observe
+- Notify
+- Cancel
+
+### Observe
+
+mbed DS initiates an observation request to change the value of a dynamic Resource.
+
+**Tip:** Related parameters for the **Observe** operation are described in the [Write Attributes](#write-attributes) section.
+
+To make your Resource observable, you need to set the Observable parameter of your object to `true`:
+
+```
+ object->set_observable(true);
+```
+
+If you want a dynamic resource to be observable, do the following when creating the resource:
+
+```
+M2MResource* create_dynamic_resource(const String &resource_name,
+ const String &resource_type,
+ M2MResourceInstance::ResourceType type,
+ bool observable,
+ bool multiple_instance =false);
+```
+
+The mbed Client will handle the observation part once you have defined the Resources to be observable.
+
+### Notify
+
+The client sends the **Notify** operation to mbed DS during a valid observation on a Resource, when the notification conditions are met.
+
+### Cancel
+
+mbed DS sends the **Cancel Observation** operation to the client to end an observation relationship for an Object Instance or a Resource.
+
+## More Information
+
+This API is based on OMA LWM2M specification. You can get the specification [here](http://technical.openmobilealliance.org/Technical/technical-information/release-program/current-releases/oma-lightweightm2m-v1-0).

+# Introduction to mbed Client
+
+mbed Client is structured as a set of modules. Each module declares which other modules it depends on. When you build a module, our build system `yotta` looks at these dependencies and installs the necessary modules before completing the build.
+
+This is also the process to build applications for the mbed Client (including the example application in the release). The application declares dependencies on the mbed Client and when it is built, `yotta` ensures that the modules (and anything that they depend on, recursively) are present before building.
+
+In this release, all the necessary modules for the examples (the ones that the examples depend on) have been pre-installed in the `yotta_modules` directory of each example program, so you do not need to download them separately. In general, `yotta` downloads and installs the necessary modules over the internet from the public yotta Registry (which saves published versions of modules) or from a specified source control URL.
+
+# Building and testing mbed Client
+
+Before embarking on your own port, you should build the core mbed Client for an existing compilation target to get an understanding of how the mbed Client builds. You can find a general guide for building the mbed Client and its example application in the mbed Client release notes.
+
+# Components of mbed Client
+
+## Component software modules
+
+The mbed Client consists of one main component. More major components will be added in the further development phases:
+
+ * `mbed-client` is the core mbed Client, providing C++ APIs for the mbed Client.
+
+This module depends on further internal modules:
+
+```
+mbed-client x.x.x
+|
+|_mbed-client-c x.x.x
+| |_mbed-client-libservice x.x.x
+|
+|_mbed-client-linux x.x.x
+```
+
+To list the dependency trees, give [`yotta list --all` command](http://docs.yottabuild.org/reference/commands.html).
+
+**Note**: In this case, we have listed the dependencies for the `x86-linux-native` compilation target. Different modules are needed for different compilation target.
+
+If you list the modules included in the mbed Client linux example, you can see that it depends directly only on the `mbed-client` and `mbed-client-linux` modules. These modules depend internally on various other modules.
+
+```
+mbed-client-linux-example x.x.x
+|
+|_mbed-client x.x.x
+ |
+ |_mbed-client-c x.x.x
+ | |_mbed-client-libservice x.x.x
+ |
+ |_mbed-client-linux 0.0.2
+```
+
+## Compilation targets
+
+This release supports only one compilation target:
+
+ * `x86-linux-native`: to compile for linux OS, using the gcc toolchain.
+
+To select the compilation target used for compiling a library or an example program, give the command `yotta target x86-linux-native` before building. More documentation on target descriptions can be found on the [yotta
+documentation site](http://docs.yottabuild.org/tutorial/targets.html).
+
+# Porting mbed Client to different platform
+
+To port mbed Client to a new platform, perform the following steps:
+
+ 1. Contact [support@mbed.org](mailto:support@mbed.org), to request for new development repositories for your target platform.
+ 2. Create a yotta compilation target for your board.
+ 3. Implement the `mbed-client-xxx` module for your target platform where `xxx` is the name for your platform (for example, `linux`).
+ 4. Make sure that your port is updated into `module.json` of the `mbed-client` module.
+ 5. Verify that your implementation is correct.
+
+The `yotta` build system is designed for easy reuse of generic modules. If you intend to support multiple platforms that share common features, it is recommended to store the common functionality into a separate module and use it for each platform.
+
+# Step 1: Creating development repositories
+
+We provide private git repositories to our partners porting mbed Client. Only the members of the mbed Client team and relevant partner contacts and engineers have access to these repositories.
+
+When you contact `support@mbed.org`, a repository will be created for your module. You also need to provide the target description of your board as follows:
+
+- **`mbed-client-<platform-name>`** is the module that provides the `mbed-client-xxx` implementation for your platform. You may choose to split it into further modules in the future, to enable sharing of code, but we recommend that you implement the port for your first board in this module itself.
+
+- **`target-<targetname>`** contains the yotta target description of the target you are porting to. This is usually your platform name.
+
+# Step 2: Creating a yotta compilation target
+
+To compile for a target board, you need a [target description](http://docs.yottabuild.org/tutorial/targets.html) that describes how to compile for the target.
+
+The `mbed-client` module uses the platform name that each target defines, to choose which `mbed-client-<platform-name>` module to depend on to provide the platform-specific implementation.
+
+The target description contains:
+* `target.json` - the target description file
+* a [CMake toolchain file](http://www.cmake.org/cmake/help/v3.0/manual/cmake-toolchains.7.html) (and any dependencies it needs) that describes how to run the compiler
+* a linker script file
+
+To select the target description, run `yotta target <targetname>`. yotta needs this to set up the build.
+
+The documentation for target descriptions is available on the [yotta documentation site](http://docs.yottabuild.org/tutorial/targets.html).
+
+An example on compiling for linux target can be found in the `yotta_targets` directory of the example application.
+
+The directory structure of a typical target description is:
+
+```
+|readme.md
+|target.json
+|_CMake
+| |_toolchain.cmake
+| |
+| |_Compiler
+| | |_GNU-ASM.cmake
+| | |_GNU-C.cmake
+| | |_GNU-CXX.cmake
+| |
+| |_Platform
+| |_xxx-GNU-C.cmake
+| |_xxx-GNU-CXX.cmake
+| |_xxx.cmake
+|
+|_ld
+ |_newtarget.ld
+```
+
+Where the `target.json` file specifies the path to the CMake toolchain (`toolchain.cmake`) that uses the standard CMake mechanisms for including compiler, platform and language-specific configuration.
+
+**Note**: Improvements are planned to the yotta target description to allow more reuse of the descriptions between targets.
+
+To make your target available locally (without publishing it), you can give `yotta link-target` command to link it into the global install targets directory:
+
+```
+# in the directory of your target:
+yotta link-target
+```
+
+You can then give `yotta link-target <targetname>` command to make the globally linked target available when compiling another module. After that, give `yotta target <targetname>` command to select your target for the compilation.
+
+# Step 3: Implementing mbed-client-xxx
+
+First, clone your `mbed-client-<your-platform-name>` module and `mbed-client` modules from GitHub.
+
+The `mbed-client-<your-platform-name>` module needs to provide a socket and timer implementation for your target platform. The `mbed-client-xxx` module should include files `m2mconnectionhandler.h`and `m2mtimer.h` from `mbed-client` and implement a corresponding `.cpp` file that points to the platform-specific private implementations of the timer and the socket.
+
+**Note**: Private implementation classes MUST be named as `M2MConnectionHandlerPimpl` and `M2MTimerPimpl`, because of forward declarations.
+
+An example of mbed-client-platform core:
+
+```
+|_module.json
+|
+|_mbed-client-platform
+| |_m2mconnectionhandlerpimpl.h
+| |_m2mtimerpimpl.h
+|
+|_source
+ |_m2mconnectionhandler.cpp
+ |_m2mconnectionhandlerpimpl.cpp
+ |_m2mtimer.cpp
+ |_m2mtimerpimpl.cpp
+```
+
+To make your module available to other modules that you want to build, you need to give [`yotta link`](http://docs.yottabuild.org/reference/commands.html#yotta-link) command to link it to the module where you want to test it out.
+
+To use your local your in-development mbed-client implementation, give the command `yotta link mbed-client-xxx` in the main `mbed-client` module.
+
+```
+# in mbed-client, link your module:
+yotta link
+```
+
+You can also just commit and push your untested code to GitHub, but it is always a good idea to test before committing.
+
+Your `mbed-client-xxx` module must provide a platform-specific implementation for the mbed-client. The APIs that needs porting are defined in the `mbed-client-linux` module. The header files contain documentation alongside the declaration of each function, where the function is described along with its parameters and return value.
+
+There are two header files that require porting for your platform:
+
+- `m2mconnectionhandler.h`
+- `m2mtimer.h`
+
+To see how this is done in Linux, check the `mbed-client-linux` module available in this package.

+/**
+\page cmsis_os_h Header File Template: cmsis_os.h
+
+The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
+Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
+its implementation.
+
+The file cmsis_os.h contains:
+ - CMSIS-RTOS API function definitions
+ - struct definitions for parameters and return types
+ - status and priority values used by CMSIS-RTOS API functions
+ - macros for defining threads and other kernel objects
+
+
+<b>Name conventions and header file modifications</b>
+
+All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
+Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
+All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
+
+Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
+These definitions can be specific to the underlying RTOS kernel.
+
+Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
+compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
+
+
+<b>Function calls from interrupt service routines</b>
+
+The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
+ - \ref osSignalSet
+ - \ref osSemaphoreRelease
+ - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
+ - \ref osMessagePut, \ref osMessageGet
+ - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
+
+Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
+from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
+
+Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
+If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
+
+
+<b>Define and reference object definitions</b>
+
+With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
+that is used throughout a project as shown below:
+
+<i>Header File</i>
+\code
+#include <cmsis_os.h> // CMSIS RTOS header file
+
+// Thread definition
+extern void thread_sample (void const *argument); // function prototype
+osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
+
+// Pool definition
+osPoolDef(MyPool, 10, long);
+\endcode
+
+
+This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
+present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
+used throughout the whole project.
+
+<i>Example</i>
+\code
+#include "osObjects.h" // Definition of the CMSIS-RTOS objects
+\endcode
+
+\code
+#define osObjectExternal // Objects will be defined as external symbols
+#include "osObjects.h" // Reference to the CMSIS-RTOS objects
+\endcode

+/**
+\page cmsis_os_h Header File Template: cmsis_os.h
+
+The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
+Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
+its implementation.
+
+The file cmsis_os.h contains:
+ - CMSIS-RTOS API function definitions
+ - struct definitions for parameters and return types
+ - status and priority values used by CMSIS-RTOS API functions
+ - macros for defining threads and other kernel objects
+
+
+<b>Name conventions and header file modifications</b>
+
+All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
+Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
+All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
+
+Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
+These definitions can be specific to the underlying RTOS kernel.
+
+Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
+compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
+
+
+<b>Function calls from interrupt service routines</b>
+
+The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
+ - \ref osSignalSet
+ - \ref osSemaphoreRelease
+ - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
+ - \ref osMessagePut, \ref osMessageGet
+ - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
+
+Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
+from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
+
+Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
+If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
+
+
+<b>Define and reference object definitions</b>
+
+With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
+that is used throughout a project as shown below:
+
+<i>Header File</i>
+\code
+#include <cmsis_os.h> // CMSIS RTOS header file
+
+// Thread definition
+extern void thread_sample (void const *argument); // function prototype
+osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
+
+// Pool definition
+osPoolDef(MyPool, 10, long);
+\endcode
+
+

+/**
+\page cmsis_os_h Header File Template: cmsis_os.h
+
+The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).
+Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents
+its implementation.
+
+The file cmsis_os.h contains:
+ - CMSIS-RTOS API function definitions
+ - struct definitions for parameters and return types
+ - status and priority values used by CMSIS-RTOS API functions
+ - macros for defining threads and other kernel objects
+
+
+<b>Name conventions and header file modifications</b>
+
+All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.
+Definitions that are prefixed \b os_ are not used in the application code but local to this header file.
+All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.
+
+Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS implementation.
+These definitions can be specific to the underlying RTOS kernel.
+
+Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is no longer
+compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation.
+
+
+<b>Function calls from interrupt service routines</b>
+
+The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR):
+ - \ref osSignalSet
+ - \ref osSemaphoreRelease
+ - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree
+ - \ref osMessagePut, \ref osMessageGet
+ - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree
+
+Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called
+from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector.
+
+Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time.
+If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.
+
+
+<b>Define and reference object definitions</b>
+
+With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file
+that is used throughout a project as shown below:
+
+<i>Header File</i>
+\code
+#include <cmsis_os.h> // CMSIS RTOS header file
+
+// Thread definition
+extern void thread_sample (void const *argument); // function prototype
+osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);
+
+// Pool definition
+osPoolDef(MyPool, 10, long);
+\endcode
+
+
+This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is
+present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be
+used throughout the whole project.
+
+<i>Example</i>
+\code
+#include "osObjects.h" // Definition of the CMSIS-RTOS objects
+\endcode
+
+\code
+#define osObjectExternal // Objects will be defined as external symbols
+#include "osObjects.h" // Reference to the CMSIS-RTOS objects
+\endcode

+# mbed TLS
+
+mbed TLS makes it trivially easy for developers to include cryptographic and SSL/TLS capabilities in their embedded products, with a minimal code footprint. It offers an SSL library with an intuitive API and readable source code.
+
+**Note:** The current release is beta, and implements no secure source of random numbers, weakening its security.
+
+Currently the only supported yotta targets are:
+- `frdm-k64f-gcc`
+- `frdm-k64f-armcc`
+- `x86-linux-native`
+- `x86-osx-native`
+
+## Sample programs
+
+This release includes the following examples:
+
+1. [**Self test:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-selftest) Tests different basic functions in the mbed TLS library.
+
+2. [**Benchmark:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-benchmark) Measures the time taken to perform basic cryptographic functions used in the library.
+
+3. [**Hashing:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-hashing) Demonstrates the various APIs for computing hashes of data (also known as message digests) with SHA-256.
+
+4. [**Authenticated encryption:**](https://github.com/ARMmbed/mbedtls/blob/development/yotta/data/example-authcrypt) Demonstrates usage of the Cipher API for encrypting and authenticating data with AES-CCM.
+
+These examples are integrated as yotta tests, so that they are built automatically when you build mbed TLS. Each of them comes with complete usage instructions as a Readme file in the repository.
+
+## Performing TLS and DTLS connections
+
+A high-level API for performing TLS and DTLS connections with mbed TLS in mbed OS is provided in a separate yotta module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). We recommend this API for TLS and DTLS connections. It is very similar to the API provided by the [sockets](https://github.com/ARMmbed/sockets) module for unencrypted TCP and UDP connections.
+
+The `mbed-tls-sockets` module includes a complete [example TLS client](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/main.cpp) with [usage instructions](https://github.com/ARMmbed/mbed-tls-sockets/blob/master/test/tls-client/README.md).
+
+## Configuring mbed TLS features
+
+mbed TLS makes it easy to disable any feature during compilation, if that feature isn't required for a particular project. The default configuration enables all modern and widely-used features, which should meet the needs of new projects, and disables all features that are older or less common, to minimize the code footprint.
+
+The list of available compilation flags is available in the fully documented [config.h file](https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h).
+
+If you need to adjust those flags, you can provide your own configuration-adjustment file with suitable `#define` and `#undef` statements. These will be included between the default definitions and the sanity checks. Your configuration file should be in your application's include directory, and can be named freely; you just need to let mbed TLS know the file's name. To do that, use yotta's [configuration system](http://docs.yottabuild.org/reference/config.html). The file's name should be in your `config.json` file, under mbedtls, as the key `user-config-file`.
+
+For example, in an application called `myapp`, if you want to enable the EC J-PAKE key exchange and disable the CBC cipher mode, you can create a file named `mbedtls-config-changes.h` in the `myapp` directory containing the following lines:
+
+ #define MBEDTLS_ECJPAKE_C
+ #define MBEDTLS_KEY_EXCHANGE_ECJPAKE_ENABLED
+
+ #undef MBEDTLS_CIPHER_MODE_CBC
+
+And then create a file named `config.json` at the root of your application with the following contents:
+
+ {
+ "mbedtls": {
+ "user-config-file": "\"myapp/mbedtls-config-changes.h\""
+ }
+ }
+
+Please note: you need to provide the exact name that will be used in the `#include` directive, including the `<>` or quotes around the name.
+
+## Getting mbed TLS from GitHub
+
+Like most components of mbed OS, mbed TLS is developed in the open and its source can be found on GitHub: [ARMmbed/mbedtls](https://github.com/ARMmbed/mbedtls). Unlike most other mbed OS components, however, you cannot just clone the repository and run `yotta build` from its root. This is because mbed TLS also exists as an independent component, so its repository includes things that are not relevant for mbed OS, as well as other build systems.
+
+The way to use mbed TLS from a clone of the GitHub repository is to run the following commands from the root of a checkout:
+
+ yotta/create-module.sh
+ cd yotta/module
+
+You can then run any yotta command you would normally run, such as `yotta build` or `yotta link`.
+
+## Differences between the standalone and mbed OS editions
+
+While the two editions share the same code base, there are still a number of differences, mainly in configuration and integration. You should keep in mind those differences when reading some articles in our [knowledge base](https://tls.mbed.org/kb), as currently all the articles are about the standalone edition.
+
+* The mbed OS edition has a smaller set of features enabled by default in `config.h`, in order to reduce footprint. While the default configuration of the standalone edition puts more emphasize on maintaining interoperability with old peers, the mbed OS edition only enables the most modern ciphers and the latest version of (D)TLS.
+
+* The following components of mbed TLS are disabled in the mbed OS edition: `net.c` and `timing.c`. This is because mbed OS includes their equivalents.
+
+* The mbed OS edition comes with a fully integrated API for (D)TLS connections in a companion module: [mbed-tls-sockets](https://github.com/ARMmbed/mbed-tls-sockets). See "Performing TLS and DTLS connections" above.
+
+## Other resources
+
+The [mbed TLS website](https://tls.mbed.org) contains many other useful
+resources for the developer, such as [developer
+documentation](https://tls.mbed.org/dev-corner), [knowledgebase
+articles](https://tls.mbed.org/kb), and a [support forum](https://tls.mbed.org/discussions).
+
+## Contributing
+
+We gratefully accept bug reports and contributions from the community. There are some requirements we need to fulfill in order to be able to integrate contributions:
+
+* Simple bug fixes to existing code do not contain copyright themselves and we can integrate without issue. The same is true of trivial contributions.
+
+* For larger contributions, such as a new feature, the code can possibly fall under copyright law. We then need your consent to share in the ownership of the copyright. We have a form for this, which we will send to you in case you submit a contribution or pull request that we deem this necessary for.
+
+To contribute, please:
+
+* [Check for open issues](https://github.com/ARMmbed/mbedtls/issues) or [start a discussion](https://tls.mbed.org/discussions) around a feature idea or a bug.
+
+* Fork the [mbed TLS repository on GitHub](https://github.com/ARMmbed/mbedtls) to start making your changes. As a general rule, you should use the "development" branch as a basis.
+
+* Write a test that shows that the bug was fixed or that the feature works as expected.
+
+* Send a pull request and bug us until it gets merged and published. We will include your name in the ChangeLog.

+ * 5 bits - Module-dependent error code
+ * 7 bits - Low level module errors

+ * For historical reasons, low-level error codes are divided in even and odd,
+ * even codes were assigned first, and -1 is reserved for other errors.
