Application resources

This example exposes four resources listed below:

  1. 3202/0/5700. Decode result of barcode data input from camera (GET).
  2. 3201/0/5850. Blink function, blinks LED 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).
  4. 3201/0/5855. Blink color, used by the blink function. Any of red, green, blue, cyan, yellow and magenta is acceptable if you are using GR-PEACH board (PUT).
  5. 3201/0/5855. Blink color, used by the blink function. Any of green, yellow, orange and red is acceptable if you are using GR-LYCHEE board (PUT).

<> 0:eb73febb2bba 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.

<> 0:eb73febb2bba 35
<> 0:eb73febb2bba 36 To configure the example application, please:
<> 0:eb73febb2bba 37
<> 0:eb73febb2bba 38 1. [Select the connection type](#connection-type).
<> 0:eb73febb2bba 39 1. [Set the client credentials](#client-credentials).
<> 0:eb73febb2bba 40 1. [Change Ethernet settings](#ethernet-settings).
<> 0:eb73febb2bba 41 1. [Change Wi-Fi settings](#wi-fi-settings).
<> 0:eb73febb2bba 42 1. [Set up an IP address](#ip-address-setup). This step is optional.
<> 0:eb73febb2bba 43
<> 0:eb73febb2bba 44 ### Connection type
<> 0:eb73febb2bba 45
dkato 2:6ec5c1c1d41c 46 The application uses "NO_CONNECT" as the default connection type. To change the connection type, set one of them in `mbed_app.json`. For example, to enable Ethernet mode:
<> 0:eb73febb2bba 47
<> 0:eb73febb2bba 48 ```json
dkato 2:6ec5c1c1d41c 49 "network-interface":{
dkato 2:6ec5c1c1d41c 50 "help": "Options are ETHERNET, WIFI_ESP8266, WIFI_BP3595, NO_CONNECT",
dkato 2:6ec5c1c1d41c 51 "value": "ETHERNET"
dkato 2:6ec5c1c1d41c 52 },
<> 0:eb73febb2bba 53 ```
<> 0:eb73febb2bba 54
<> 0:eb73febb2bba 55 ### Client credentials
<> 0:eb73febb2bba 56
<> 0:eb73febb2bba 57 To register the application to the Connector service, you need to create and set the client side certificate.
<> 0:eb73febb2bba 58
<> 0:eb73febb2bba 59 1. Go to [mbed Device Connector](https://connector.mbed.com) and log in with your mbed account.
<> 0:eb73febb2bba 60 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.
<> 0:eb73febb2bba 61 1. Replace the contents in `security.h` of this project's directory with content copied above.
<> 0:eb73febb2bba 62
<> 0:eb73febb2bba 63 ### Ethernet settings
<> 0:eb73febb2bba 64
<> 0:eb73febb2bba 65 For running the example application using Ethernet, you need:
<> 0:eb73febb2bba 66
<> 0:eb73febb2bba 67 - An Ethernet cable.
<> 0:eb73febb2bba 68 - An Ethernet connection to the internet.
dkato 2:6ec5c1c1d41c 69 - MAC address setting. To set MAC address, add fllowing function to main.cpp. (When using Wifi, setting of MAC address is not necessary.)
dkato 2:6ec5c1c1d41c 70 ```
dkato 2:6ec5c1c1d41c 71 // set mac address
dkato 2:6ec5c1c1d41c 72 void mbed_mac_address(char *mac) {
dkato 2:6ec5c1c1d41c 73 mac[0] = 0x00;
dkato 2:6ec5c1c1d41c 74 mac[1] = 0x02;
dkato 2:6ec5c1c1d41c 75 mac[2] = 0xF7;
dkato 2:6ec5c1c1d41c 76 mac[3] = 0xF0;
dkato 2:6ec5c1c1d41c 77 mac[4] = 0x00;
dkato 2:6ec5c1c1d41c 78 mac[5] = 0x00;
dkato 2:6ec5c1c1d41c 79 }
dkato 2:6ec5c1c1d41c 80 ```
<> 0:eb73febb2bba 81
<> 0:eb73febb2bba 82 ### IP address setup
<> 0:eb73febb2bba 83
dkato 2:6ec5c1c1d41c 84 This example uses IPv4 to communicate with the [mbed Device Connector Server](https://api.connector.mbed.com) except for 6LoWPAN ND and Thread.
dkato 2:6ec5c1c1d41c 85 The example program should automatically get an IP address from the router when connected over Ethernet or WiFi.
<> 0:eb73febb2bba 86 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.
<> 0:eb73febb2bba 87
<> 0:eb73febb2bba 88 ## Building the example
<> 0:eb73febb2bba 89
dkato 2:6ec5c1c1d41c 90 To build the example using mbed CLI:
<> 0:eb73febb2bba 91
<> 0:eb73febb2bba 92 1. Open a command line tool and navigate to the project’s directory.
dkato 2:6ec5c1c1d41c 93
dkato 2:6ec5c1c1d41c 94 2. Import this example:
dkato 2:6ec5c1c1d41c 95
dkato 2:6ec5c1c1d41c 96 ```
dkato 2:6ec5c1c1d41c 97 mbed import http://mbed.org/teams/Renesas/code/GR-PEACH_mbed-os-client-ZXingSample/
dkato 2:6ec5c1c1d41c 98 ```
dkato 2:6ec5c1c1d41c 99
dkato 2:6ec5c1c1d41c 100 3. To build the application, select the hardware board and build the toolchain using the command:
dkato 2:6ec5c1c1d41c 101
dkato 2:6ec5c1c1d41c 102 ```
dkato 2:6ec5c1c1d41c 103 mbed compile -m RZ_A1H -t GCC_ARM -c
dkato 2:6ec5c1c1d41c 104 ```
dkato 2:6ec5c1c1d41c 105
dkato 2:6ec5c1c1d41c 106 mbed CLI builds a binary file under the project’s `BUILD/` directory.
dkato 2:6ec5c1c1d41c 107
dkato 2:6ec5c1c1d41c 108 4. Plug the Ethernet cable into the board if you are using Ethernet mode.
dkato 2:6ec5c1c1d41c 109
dkato 2:6ec5c1c1d41c 110 5. Plug the micro-USB cable into the **OpenSDA** port. The board is listed as a mass-storage device.
dkato 2:6ec5c1c1d41c 111
1050186 6:ea24d9271ff1 112 6. Drag the binary `BUILD/RZ_A1H/GCC_ARM/XXXXXXXX.bin` to the board to flash the application.
dkato 2:6ec5c1c1d41c 113
dkato 2:6ec5c1c1d41c 114 7. 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.
dkato 2:6ec5c1c1d41c 115
dkato 2:6ec5c1c1d41c 116 8. Press the **Reset** button on the board to run the program.
dkato 2:6ec5c1c1d41c 117
dkato 2:6ec5c1c1d41c 118 9. For verification, continue to the [Monitoring the application](#monitoring-the-application) chapter.

<> 0:eb73febb2bba 161
dkato 2:6ec5c1c1d41c 162 The application exposes four [resources](https://docs.mbed.com/docs/mbed-device-connector-web-interfaces/en/latest/#the-mbed-device-connector-data-model):
<> 0:eb73febb2bba 163
<> 0:eb73febb2bba 164 1. `3202/0/5700`. Decoded String of Barcode Data (GET).
<> 0:eb73febb2bba 165 2. `3201/0/5850`. Blink function, blinks `LED1` when executed (POST).
