+# Getting started with mbed Client on mbed OS
+
+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.
+
+The application:
+
+* Connects to network with WiFi or Ethernet.
+* Registers with mbed Device Connector.
+* Gives mbed Device Connector access to its resources (read and write).
+* Records the number of clicks on the device’s button and sends the number to mbed Device Connector.
+* Lets you control the blink pattern of the LED on the device (through mbed Device Connector).
+
+## Required hardware
+
+* [Renesas GR-PEACH](https://developer.mbed.org/platforms/Renesas-GR-PEACH/).
+* 1-2 micro-USB cables.
+* Ethernet cable and connection to the internet.
+
+## Requirements for Renesas GR-PEACH
+* To get the application registering successfully on non K64F boards , you need Edit the `mbed_app.json` file to add `NULL_ENTROPY`  feature for mbedTLS:
+
+```
+""macros": ["MBEDTLS_USER_CONFIG_FILE=\"mbedtls_mbed_client_config.h\"",
+            "MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES",
+            "MBEDTLS_TEST_NULL_ENTROPY"],
+```
+
+## Required software
+
+* [ARM mbed account](https://developer.mbed.org/account/login/?next=/).
+* [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).
+* [Serial port monitor](https://developer.mbed.org/handbook/SerialPC#host-interface-and-terminal-applications).
+
+## Application setup
+
+To configure the example application, please:
+
+1. [Select the connection type](#connection-type).
+1. [Set the client credentials](#client-credentials).
+1. [Change Ethernet settings](#ethernet-settings).
+1. [Change Wi-Fi settings](#wi-fi-settings).
+1. [Set up an IP address](#ip-address-setup). This step is optional.
+1. [Change the socket type](#changing-socket-type). This step is optional.
+
+### Connection type
+
+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:
+
+```json
+    "network-interface": {
+        "help": "options are ETHERNET,WIFI,MESH_LOWPAN_ND,MESH_THREAD.",
+        "value": "MESH_LOWPAN_ND"
+    }
+```
+
+### Client credentials
+
+To register the application to the Connector service, you need to create and set the client side certificate.
+
+1. Go to [mbed Device Connector](https://connector.mbed.com) and log in with your mbed account.
+1. On mbed Device Connector, go to [My Devices > Security credentials](https://connector.mbed.com/#credentials) and click the **Get my device security credentials** button to get new credentials for your device.
+1. Replace the contents in `security.h` of this project's directory with content copied above.
+
+### Ethernet settings
+
+For running the example application using Ethernet, you need:
+
+- An Ethernet cable.
+- An Ethernet connection to the internet.
+
+### Wi-Fi settings (BP3595)
+
+The example application uses BP3595 WiFi Interface for managing the wireless connectivity. To run this application using WiFi, you need:
+
+1. An [BP3595](https://developer.mbed.org/components/BP3595-for-GR-PEACH/) WiFi module
+1. Mount the WiFi module onto [Renesas GR-PEACH](https://developer.mbed.org/platforms/Renesas-GR-PEACH/)
+1. In the `mbed_app.json` file, change
+```json
+    "network-interface": {
+        "help": "options are ETHERNET,WIFI,MESH_LOWPAN_ND,MESH_THREAD.",
+        "value": "WIFI"
+    }
+```
+
+Provide your WiFi SSID and password here and leave `\"` in the beginning and end of your SSID and password (as shown in the example below). Otherwise, the example cannot pick up the SSID and password in correct format.
+```json
+    "wifi-ssid": {
+        "help": "WiFi SSID",
+        "value": "\"SSID\""
+    },
+    "wifi-password": {
+        "help": "WiFi Password",
+        "value": "\"Password\""
+    }
+```
+
+Specify the security protocol in accordance with your wireless network. By default, NSAPI_SECURITY_WPA2 is specified. That means WPA2 is available. If you would like to use WEP instead of WPA2, please specify NSAPI_SECURITY_WEP here.
+```json
+    "wifi-security": {
+        "help": "Type of encryption for connection",
+        "value": "NSAPI_SECURITY_WPA2 or NSAPI_SECURITY_WEP"
+    }
+```
+
+Short the jumper JP1 of [Audio Camera Shield](https://developer.mbed.org/teams/Renesas/wiki/Audio_Camera-shield) to supply the power to BP3595.
+
+<span class="tips">**TODO:** Need to clarify when Audio Camera Shield is NOT available.</span>
+
+### IP address setup
+
+This example uses IPv4 to communicate with the [mbed Device Connector Server](https://api.connector.mbed.com) except for 6LoWPAN ND and Thread. The example program should automatically get an IPv4 address from the router when connected over Ethernet.
+
+If your network does not have DHCP enabled, you have to manually assign a static IP address to the board. We recommend having DHCP enabled to make everything run smoothly.
+
+### Changing socket type
+
+Your device can connect to mbed Device Connector via UDP or TCP binding mode. The default is UDP. The binding mode cannot be changed in 6LoWPAN ND or Thread mode.
+
+To change the binding mode:
+
+1. In the `simpleclient.h` file, find the parameter `SOCKET_MODE`. The default is `M2MInterface::UDP`.
+1. To switch to TCP, change it to `M2MInterface::TCP`.
+1. Rebuild and flash the application.
+
+<span class="tips">**Tip:** The instructions in this document remain the same, irrespective of the socket mode you select.</span>
+
+## Building the example
+
+To build the example application:
+
+1. Clone [this](https://github.com/ARMmbed/mbed-os-example-client) repository.
+1. Open a command line tool and navigate to the project’s directory.
+1. Update mbed-os sources using the `mbed update` command.
+1. [Configure](#application-setup) the client application.
+1. Build the application by selecting the hardware board and build the toolchain using the command `mbed compile -m RZ_A1H -t GCC_ARM -c -j0`. mbed-cli builds a binary file under the project’s `.build` directory.
+1. Plug the Ethernet cable into the board if you are using Ethernet mode.
+1. If you are using 6LoWPAN ND or Thread mode, connect and power on the gateway first.
+1. Plug the micro-USB cable into the **OpenSDA** port. The board is listed as a mass-storage device.
+1. Drag the binary `.build/RZ_A1H/GCC_ARM/mbed-os-example-client.bin` to the board to flash the application.
+1. The board is automatically programmed with the new binary. A flashing LED on it indicates that it is still working. When the LED stops blinking, the board is ready to work.
+1. Press the **RESET** button on the board to run the program.
+1. For verification, continue to the [Monitoring the application](#monitoring-the-application) chapter.
+
+## Monitoring the application
+
+The application prints debug messages over the serial port, so you can monitor its activity with a serial port monitor. The application uses baud rate 115200.
+
+<span class="notes">**Note:** Instructions to set this up are located [here](https://developer.mbed.org/handbook/SerialPC#host-interface-and-terminal-applications).</span>

+
+<span class="notes">**Note:** Device name is the endpoint name you will need later on when [testing the application](https://github.com/ARMmbed/mbed-os-example-client#testing-the-application) chapter.</span>
+
+When the barcode data is successfully decoded, you should see the decoded string.
+
+## Testing the application
+
+1. Flash the application.
+1. Verify that the registration succeeded. You should see `Registered object successfully!` printed to the serial port.
+1. On mbed Device Connector, go to [My devices > Connected devices](https://connector.mbed.com/#endpoints). Your device should be listed here.
+1. Input the barcode data via camera. (If the decode is successfully carried out, decoded string should be uploaded onto mbed Device Connector)
+1. Go to [Device Connector > API Console](https://connector.mbed.com/#console).
+1. Enter `https://api.connector.mbed.com/endpoints/DEVICE_NAME/3202/0/5700` in the URI field and click **TEST API**. Replace `DEVICE_NAME` with your actual endpoint name. The device name can be found in the `security.h` file, see variable `MBED_ENDPOINT_NAME` or it can be found from the traces [Monitoring the application](https://github.com/ARMmbed/mbed-os-example-client#monitoring-the-application).
+1. Decoded string is shown.
+1. Press the `SW3` button to unregister from mbed Device Connector. You should see `Unregistered Object Successfully` printed to the serial port and the LED starts blinking. This will also stop your application. Press the `RESET` button to run the program again.

+
+<span class="tips">**Tip:** If you get an error, for example `Server Response: 410 (Gone)`, clear your browser's cache, log out, and log back in.</span>
+
+<span class="notes">**Note:** Only GET methods can be executed through [Device Connector > API Console](https://connector.mbed.com/#console). For other methods check the [mbed Device Connector Quick Start](https://github.com/ARMmbed/mbed-connector-api-node-quickstart).
+
+### Application resources
+
+The application exposes three [resources](https://docs.mbed.com/docs/mbed-device-connector-web-interfaces/en/latest/#the-mbed-device-connector-data-model):
+
+1. `3202/0/5700`. Decoded String of Barcode Data (GET).
+2. `3201/0/5850`. Blink function, blinks `LED1` when executed (POST).
+3. `3201/0/5853`. Blink pattern, used by the blink function to determine how to blink. In the format of `1000:500:1000:500:1000:500` (PUT).
+
+For information on how to get notifications when resource 1 changes, or how to use resources 2 and 3, take a look at the [mbed Device Connector Quick Start](https://github.com/Osamu-Nakamura/mbed-connector-api-node-quickstart).
