Yogesh Pande 0:7d5ec759888b 1 # Getting started with mbed Client on mbed OS
Yogesh Pande 0:7d5ec759888b 2
Yogesh Pande 0:7d5ec759888b 3 This is the mbed Client example for mbed OS (we also have one for [Linux](https://github.com/ARMmbed/mbed-client-linux-example)). It demonstrates how to register a device with mbed Device Connector, how to read and write values, and how to deregister. If you are unfamiliar with mbed Device Connector, we recommend that you read [the introduction to the data model](https://docs.mbed.com/docs/mbed-device-connector-web-interfaces/en/latest/#the-mbed-device-connector-data-model) first.

mbed_official 22:e39e09d79a63 21 ## Supported Target hardware configurations
mbed_official 22:e39e09d79a63 22
mbed_official 22:e39e09d79a63 23 This example has been tested in following configuration
mbed_official 22:e39e09d79a63 24 * K64F + NXP MCR20 15.4 shield (mesh `NANOSTACK_FULL` mode)
mbed_official 22:e39e09d79a63 25 * NUCLEO_F429ZI + ATMEL AT233 15.4 shield (mesh `LOWPAN_ROUTER` mode)
mbed_official 22:e39e09d79a63 26 * K64F (Ethernet)
mbed_official 22:e39e09d79a63 27 * NUCLEO_F429ZI (Ethernet)
mbed_official 22:e39e09d79a63 28 * UBLOX_EVK_ODIN_W2 (Ethernet)
mbed_official 22:e39e09d79a63 29 * K64F + GROVE SEEED shield (Wifi)
mbed_official 22:e39e09d79a63 30 * NUCLEO_F429ZI + GROVE SEEED shield (Wifi)
mbed_official 22:e39e09d79a63 31
mbed_official 22:e39e09d79a63 32 Apart from this, this example can work on other mbed OS supported hardware boards which support any of the given network interface including Ethernet, WiFi, Mesh (6LoWPAN) or Thread, provided the configuration fulfills condition that the target hardware has TLS entropy implemented for it and the complete example configuration of mbed Client, selected network interface and mbed OS components fits into hardware's given memory size (Flash size and RAM size).
mbed_official 22:e39e09d79a63 33
mbed_official 21:b88cdeb5b302 34 ## Requirements for non-K64F boards
mbed_official 21:b88cdeb5b302 35
mbed_official 21:b88cdeb5b302 36 * This example requires TLS functionality to be enabled on mbed TLS.
mbed_official 21:b88cdeb5b302 37 On devices where hardware entropy is not present, TLS is disabled by default.
mbed_official 21:b88cdeb5b302 38 This would result in compile time failures or linking failures.
mbed_official 7:9a1ee269650b 39
mbed_official 21:b88cdeb5b302 40 To learn why entropy is required, read the
mbed_official 21:b88cdeb5b302 41 [TLS Porting guide](https://docs.mbed.com/docs/mbed-os-handbook/en/5.2/advanced/tls_porting/).
mbed_official 21:b88cdeb5b302 42
mbed_official 21:b88cdeb5b302 43 * On non-K64F boards, there is no unregistration functionality and
mbed_official 21:b88cdeb5b302 44 button presses are simulated through timer ticks incrementing every 15 seconds.
mbed_official 7:9a1ee269650b 45
Yogesh Pande 0:7d5ec759888b 46 ## Required software
Yogesh Pande 0:7d5ec759888b 47
Yogesh Pande 0:7d5ec759888b 48 * [ARM mbed account](https://developer.mbed.org/account/login/?next=/).
Yogesh Pande 0:7d5ec759888b 49 * [mbed-cli](https://github.com/ARMmbed/mbed-cli) - to build the example programs. To learn how to build mbed OS applications with mbed-cli, see [the user guide](https://github.com/ARMmbed/mbed-cli/blob/master/README.md).
Yogesh Pande 0:7d5ec759888b 50 * [Serial port monitor](https://developer.mbed.org/handbook/SerialPC#host-interface-and-terminal-applications).
Yogesh Pande 0:7d5ec759888b 51
Yogesh Pande 0:7d5ec759888b 52 ## Application setup
Yogesh Pande 0:7d5ec759888b 53
mbed_official 21:b88cdeb5b302 54 To configure the example application:
Yogesh Pande 0:7d5ec759888b 55
Yogesh Pande 0:7d5ec759888b 56 1. [Select the connection type](#connection-type).
Yogesh Pande 0:7d5ec759888b 57 1. [Set the client credentials](#client-credentials).
Yogesh Pande 0:7d5ec759888b 58 1. [Change 6LoWPAN ND & Thread settings](#6lowpan-nd-and-thread-settings).

Yogesh Pande 0:7d5ec759888b 63
Yogesh Pande 0:7d5ec759888b 64 ### Connection type
Yogesh Pande 0:7d5ec759888b 65
Yogesh Pande 0:7d5ec759888b 66 The application uses Ethernet as the default connection type. To change the connection type, set one of them in `mbed_app.json`. For example, to enable 6LoWPAN ND mode:
Yogesh Pande 0:7d5ec759888b 67
Yogesh Pande 0:7d5ec759888b 68 ```json
Yogesh Pande 0:7d5ec759888b 69 "network-interface": {
Yogesh Pande 0:7d5ec759888b 70 "help": "options are ETHERNET,WIFI,MESH_LOWPAN_ND,MESH_THREAD.",
Yogesh Pande 0:7d5ec759888b 71 "value": "MESH_LOWPAN_ND"
Yogesh Pande 0:7d5ec759888b 72 }
Yogesh Pande 0:7d5ec759888b 73 ```
Yogesh Pande 0:7d5ec759888b 74
Yogesh Pande 0:7d5ec759888b 75 ### Client credentials
Yogesh Pande 0:7d5ec759888b 76
mbed_official 21:b88cdeb5b302 77 To register the application with the Connector service, you need to create and set the client side certificate.
Yogesh Pande 0:7d5ec759888b 78
Yogesh Pande 0:7d5ec759888b 79 1. Go to [mbed Device Connector](https://connector.mbed.com) and log in with your mbed account.
mbed_official 21:b88cdeb5b302 80 1. On mbed Device Connector, go to [My Devices > Security credentials](https://connector.mbed.com/#credentials) and click the **Get my device security credentials** to get new credentials for your device.
mbed_official 21:b88cdeb5b302 81 1. Replace the contents in the `security.h` file of this project's directory with the content copied above.
Yogesh Pande 0:7d5ec759888b 82
Yogesh Pande 0:7d5ec759888b 83 ### 6LoWPAN ND and Thread settings
Yogesh Pande 0:7d5ec759888b 84
mbed_official 21:b88cdeb5b302 85 First, you need to select the RF driver to be used by the 6LoWPAN/Thread stack. This example supports [AT86RF233/212B](https://github.com/ARMmbed/atmel-rf-driver) and [NXP-MCR20a](https://github.com/ARMmbed/mcr20a-rf-driver) radio shields.
Yogesh Pande 1:e06e899acba6 86
mbed_official 21:b88cdeb5b302 87 To add the Atmel driver to you application from command line, call: `mbed add https://github.com/ARMmbed/atmel-rf-driver`.
mbed_official 21:b88cdeb5b302 88 Please make sure that the `mbed_app.json` file points to the correct radio driver type:
Yogesh Pande 1:e06e899acba6 89
mbed_official 21:b88cdeb5b302 90 ```json
mbed_official 21:b88cdeb5b302 91 "mesh_radio_type": {
mbed_official 21:b88cdeb5b302 92 "help": "options are ATMEL, MCR20",
mbed_official 21:b88cdeb5b302 93 "value": "ATMEL"
mbed_official 21:b88cdeb5b302 94 },
mbed_official 21:b88cdeb5b302 95 ```
Yogesh Pande 1:e06e899acba6 96
mbed_official 21:b88cdeb5b302 97 Then you need to enable ARM IPv6/6LoWPAN stack. Edit the `mbed_app.json` file to add `NANOSTACK` feature with the particular configuration of the stack:
Yogesh Pande 1:e06e899acba6 98
Yogesh Pande 1:e06e899acba6 99 ```
mbed_official 21:b88cdeb5b302 100 "target.features_add": ["NANOSTACK", "LOWPAN_ROUTER", "COMMON_PAL"],
mbed_official 21:b88cdeb5b302 101 ```
mbed_official 21:b88cdeb5b302 102
mbed_official 21:b88cdeb5b302 103 If your connection type is `MESH_THREAD` then you may want to use the THREAD_ROUTER configuration:
mbed_official 21:b88cdeb5b302 104
mbed_official 21:b88cdeb5b302 105 ```
mbed_official 21:b88cdeb5b302 106 "target.features_add": ["NANOSTACK", "THREAD_ROUTER", "COMMON_PAL"],
Yogesh Pande 1:e06e899acba6 107 ```
Yogesh Pande 1:e06e899acba6 108
Yogesh Pande 0:7d5ec759888b 109 6LoWPAN ND and Thread use IPv6 for connectivity. Therefore, you need to verify first that you have a working IPv6 connection. To do that, ping the Connector IPv6 address `2607:f0d0:2601:52::20` from your network.
Yogesh Pande 0:7d5ec759888b 110
mbed_official 21:b88cdeb5b302 111 <span class="notes">**Note:** If you are using the [k64f-border-router](https://github.com/ARMmbed/k64f-border-router) (that can be used only as a 6LoWPAN BR and only with FRDM-K64F), you need to enable another security feature. By default, the `k64f-border-router` uses `PSK` as security.</span>
mbed_official 21:b88cdeb5b302 112
mbed_official 21:b88cdeb5b302 113 You can enable the security here on your mbed-os-example-client application, for example:
mbed_official 6:8fff223f3f84 114
mbed_official 6:8fff223f3f84 115 ```json
mbed_official 6:8fff223f3f84 116 "target_overrides": {
mbed_official 6:8fff223f3f84 117 "*": {
mbed_official 6:8fff223f3f84 118 "mbed-mesh-api.6lowpan-nd-security-mode": "PSK",
mbed_official 6:8fff223f3f84 119 }
mbed_official 6:8fff223f3f84 120 }
mbed_official 6:8fff223f3f84 121 ```
mbed_official 21:b88cdeb5b302 122
mbed_official 21:b88cdeb5b302 123 Alternatively, you can remove the link layer security from the `k64f-border-router`. To do that, change the [mbed_app.json](https://github.com/ARMmbed/k64f-border-router/blob/master/mbed_app.json) fetched from the `k64f-border-router` repository, for example:
mbed_official 6:8fff223f3f84 124
mbed_official 6:8fff223f3f84 125 ```json
mbed_official 6:8fff223f3f84 126 "config": {
mbed_official 6:8fff223f3f84 127 "security-mode": "NONE",
mbed_official 6:8fff223f3f84 128 }
mbed_official 6:8fff223f3f84 129 ```
mbed_official 21:b88cdeb5b302 130
Yogesh Pande 0:7d5ec759888b 131 #### mbed gateway
Yogesh Pande 0:7d5ec759888b 132
Yogesh Pande 0:7d5ec759888b 133 To connect the example application in 6LoWPAN ND or Thread mode to Connector, you need to set up an mbed 6LoWPAN gateway router as follows:
Yogesh Pande 0:7d5ec759888b 134
Yogesh Pande 0:7d5ec759888b 135 1. Use an Ethernet cable to connect the mbed 6LoWPAN gateway router to the internet.
Yogesh Pande 0:7d5ec759888b 136 2. Use a micro-USB cable to connect the mbed 6LoWPAN gateway router to your computer. The computer will list the router as removable storage.
Yogesh Pande 0:7d5ec759888b 137 3. The firmware for the gateway is located in the `GW_Binary` folder in the root of this example. Select the binary matching your application bootstrap mode:
Yogesh Pande 0:7d5ec759888b 138
Yogesh Pande 0:7d5ec759888b 139 * For the **6LoWPAN ND** bootstrap, use `gateway6LoWPANDynamic.bin`.
Yogesh Pande 0:7d5ec759888b 140 * For the **Thread** bootstrap, use `gatewayThreadDynamic.bin`.
Yogesh Pande 0:7d5ec759888b 141
Yogesh Pande 0:7d5ec759888b 142 The dynamic binaries use IPv6 autoconfiguration and enable the client to connect to the Connector service. The static binaries create a site-local IPv6 network and packets cannot be routed outside.
Yogesh Pande 0:7d5ec759888b 143
Yogesh Pande 0:7d5ec759888b 144 4. Copy the gateway binary file to the mbed 6LoWPAN gateway router to flash the device. The device reboots automatically after flashing. If that does not happen, press the **Reset** button on the board.
Yogesh Pande 0:7d5ec759888b 145
Yogesh Pande 0:7d5ec759888b 146 You can view debug traces from the gateway with a serial port monitor. The gateway uses baud rate 460800. The gateway IPv6 address is correctly configured when the following trace is visible: `Eth bootstrap ready, IP=XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX`.
Yogesh Pande 0:7d5ec759888b 147
Yogesh Pande 0:7d5ec759888b 148 #### Channel settings
Yogesh Pande 0:7d5ec759888b 149
Yogesh Pande 0:7d5ec759888b 150 The default 2.4GHz channel settings are already defined by the [mbed-mesh-api](https://github.com/ARMmbed/mbed-mesh-api) to match the mbed gateway settings. The application can override these settings by adding them to the `mbed_app.json` file in the main project directory. For example:
Yogesh Pande 0:7d5ec759888b 151
Yogesh Pande 0:7d5ec759888b 152 ```json
Yogesh Pande 0:7d5ec759888b 153 "target_overrides": {
Yogesh Pande 0:7d5ec759888b 154 "*": {
Yogesh Pande 0:7d5ec759888b 155 "mbed-mesh-api.6lowpan-nd-channel-page": 0,
Yogesh Pande 0:7d5ec759888b 156 "mbed-mesh-api.6lowpan-nd-channel": 12,
Yogesh Pande 0:7d5ec759888b 157 "mbed-mesh-api.thread-config-channel-page": 0,
Yogesh Pande 0:7d5ec759888b 158 "mbed-mesh-api.thread-config-channel": 12
Yogesh Pande 0:7d5ec759888b 159 }
Yogesh Pande 0:7d5ec759888b 160 }
Yogesh Pande 0:7d5ec759888b 161 ```
Yogesh Pande 0:7d5ec759888b 162
Yogesh Pande 0:7d5ec759888b 163 For sub-GHz shields (AT86RF212B) use the following overrides, **6LoWPAN ND only**:
Yogesh Pande 0:7d5ec759888b 164
Yogesh Pande 0:7d5ec759888b 165 ```json
Yogesh Pande 0:7d5ec759888b 166 "mbed-mesh-api.6lowpan-nd-channel-page": 2,
Yogesh Pande 0:7d5ec759888b 167 "mbed-mesh-api.6lowpan-nd-channel": 1
Yogesh Pande 0:7d5ec759888b 168 ```
Yogesh Pande 0:7d5ec759888b 169
mbed_official 21:b88cdeb5b302 170 For more information about the radio shields, see [the related documentation](docs/radio_module_identify.md). All configurable settings can be found in the `mbed-os-example-client/mbed-os/features/FEATURE_IPV6/mbed-mesh-api/mbed_lib.json` file.
Yogesh Pande 0:7d5ec759888b 171
Yogesh Pande 0:7d5ec759888b 172 #### Thread-specific settings
Yogesh Pande 0:7d5ec759888b 173
Yogesh Pande 0:7d5ec759888b 174 With Thread, you can change the operating mode of the client from the default router mode to a sleepy end device by adding the following override to the `mbed_app.json` file:
Yogesh Pande 0:7d5ec759888b 175
Yogesh Pande 0:7d5ec759888b 176 ```json
Yogesh Pande 0:7d5ec759888b 177 "mbed-mesh-api.thread-device-type": "MESH_DEVICE_TYPE_THREAD_SLEEPY_END_DEVICE"
Yogesh Pande 0:7d5ec759888b 178 ```
Yogesh Pande 0:7d5ec759888b 179
Yogesh Pande 0:7d5ec759888b 180 ### Ethernet settings
