Introduction

This page describes how to build the images to connect to the Azure IoT Hub on the R-Car, and run the sample module.

Environment

Host PC

OS Ubuntu 20.04 LTS (64bit)
Memory 8 GB or more
Storage At least 100 GB free

Boards confirmed to work

Board SoC Confirmed
R-Car Starter Kit Premier(H3) v2.0 OK
CCPF + R-Car Starter Kit Premier(H3) v2.0 OK
R-Car Starter Kit Pro(M3) v1.0 OK
R-Car Starter Kit Pro(M3) v3.0 OK
CCPF + R-Car Starter Kit Pro(M3) v1.0 OK

Set up in the Azure

  1. Create an Azure account
    Create an Azure account with reference to https://azure.microsoft.com/en-us/free/.
  2. Create an Azure IoT Hub
    Create an Azure IoT Hub with reference to Create an IoT hub.
  3. Register an Azure Device
    Access https://portal.azure.com/ and select the IoT Hub you created in the previous step.
    Select "IoT Edge" under "Device Management" in the side menu, and then click "+ Add IoT Edge Device".

    Then, set an arbitrary name for "Device ID" and click "Save" without changing the other settings.
    Finally, select "IoT Edge" among "Device Management" in the side menu, and click the device ID you created to check the "Primary Connection String".
    (The "Primary Connection String" is used in the "Procedure on the target board" section.)

  4. Add the Azure module
    Add the Simulated Temperature Sensor module with reference to Deploy a module.

Build

  1. Install the required packages
    $ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
    build-essential chrpath socat cpio python3 python3-pip python3-pexpect \
    xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa \

  2. Set up initial git configuration
    $ git config --global user.email "you@example.com"
    $ git config --global user.name "Your Name"
    
  3. Create the following script(build.sh) for building
    #!/bin/bash
    
    BOARD_LIST=("h3ulcb" "m3ulcb" "h3ulcb-ccpf-sk" "m3ulcb-ccpf-sk")

  4. Build
    $ chmod a+x build.sh
    $ ./build.sh <target_board_name>
    
    target_board_name is specified for each board according to the following table:
    R-car-sk-target-board-name.png

    Depending on the performance of the host PC, it may take several hours for the build to complete.
    When the build completes successfully, you will see the following output:
    NOTE: Tasks Summary: Attempted 4704 tasks of which 31 didn't need to be rerun and all succeeded.
    
  5. Check the built images
    The built images are stored in the following:
     <target_board_name>/build/tmp/deploy/images/<target_board_name>/
  6. Write the images to the SD card
    Write the images to the SD card with reference to Loading kernel and rootfs via eMMC/SD card.
    18px <translate> Note:</translate> Please replace "core-image-weston" with "core-image-minimal".

Run the sample module

  1. Procedure on the target board
    1. Turn on the target board
      1. Insert the SD card into the target board, and connect the LAN cable to it.
      2. Use a microUSB cable to connect the target board, connect a power supply to it, and connect to serial console.
      3. Power on.
        Short-press SW8 "Power" to switch the board on.
        If the board is attached to the CCPF board, short-press SW4 "Power" instead of SW8.
    2. Configure U-Boot to boot from SD card
      Refer to the Configure U-Boot to boot from SD card.
    3. Connect to the IoT Hub
      Configure to connect to the IoT Hub.
      1. Add a write permission to "/etc/iotedge/config.yaml".
        $ chmod +w /etc/iotedge/config.yaml
        
      2. Set the "Primary Connection String" to device_connection_string.
        $ vi /etc/iotedge/config.yaml
          device_connection_string: "<ADD DEVICE CONNECTION STRING HERE>" ← ★
        
        18px <translate> Note:</translate> See Register an Azure Device for the "Primary Connection String".
      3. Remove a write permission from "/etc/iotedge/config.yaml".
        $ chmod -w /etc/iotedge/config.yaml
        
      4. Restart the IoT Edge daemon.
        $ systemctl restart iotedge
        
    4. IoT Edge Device の動作確認
      端末側でiotedge daemon Active となっていることを確認する。
      $ systemctl status iotedge --no-page
      
      Azure-status-no-page.png
      端末側でモジュールがデプロイされ running 状態になっていることを確認する。
      18px <translate> Note:</translate>デプロイされるまでには数分時間がかかるため、注意すること。
      $ iotedge list
      
      Azure-list.png
  2. Azure IoT Explorer での動作手順
    Azure IoT Explorer で端末からメッセージが送信されていることを確認する。
    1. Azure IoT Explorer をダウンロード / インストール
      下記サイトからインストーラーをダウンロードする。
      https://github.com/Azure/azure-iot-explorer/releases
      18px <translate> Note:</translate>最新版のAzure.IoT.Explorer.preview.0.14.7 では、テレメトリが受信できなかったため、Azure.IoT.Explorer.preview.0.14.1 を使用
    2. Azure IoT Explorer を起動する
    3. IoT Hub の iothubowner 接続文字列を取得する。
      Azure ポータルの「IoT Hub」→ 作成した IoT Hub を選択し、サイドメニューから「共有アクセスポリシー」→「iothubowner」→「プライマリ接続文字列」をコピーする。

    4. IoT Hub を IoT Explorer に登録する
      Azure IoT Explorerのサイドメニューから「IoT hubs」を選択し、「+ Add connection」を押下する。
      「Connection string」に上記でコピーした「iothubowner 接続文字列」をペーストして、「Save」を押下する。
    5. テレメトリを確認する
      サイドメニューの「Telemetry」を選択して、「Start」を押下する。
      しばらくすると以下のようにテレメトリが表示される。
