When doing development for Azure IoT solutions, developers may want to test and debug his cloud solution with a real device. However, not every developer has a real device in his hand.\u00a0 With the Azure IoT Toolkit extension<\/a> for Visual Studio Code, you could easily use VS Code as a device simulator to quickly interact with Azure IoT Hub. Let’s see how easy it is to send a D2C (device-to-cloud) in VS Code! Say Hello to IoT Hub in VS Code in 5 minutes!<\/p>\n

Prerequisites<\/h2>\n
    \n
  1. If you don\u2019t have an Azure subscription, create a\u00a0free account<\/a>\u00a0before you begin.<\/li>\n
  2. Install the Visual Studio Code extension\u00a0Azure IoT Toolkit<\/a>.<\/li>\n<\/ol>\n

    Create an IoT hub<\/h2>\n

    The first step is to\u00a0create an IoT hub\u00a0in your subscription from VS Code.<\/p>\n

      \n
    1. Click\u00a0… > Create IoT Hub<\/strong>\u00a0at\u00a0AZURE IOT HUB DEVICES<\/strong>\u00a0tab, or type\u00a0Azure IoT Hub: Create IoT Hub<\/strong>\u00a0in\u00a0Command Palette. (If you want to use an existing IoT Hub, Click\u00a0… > Select IoT Hub<\/strong>\u00a0at\u00a0AZURE IOT HUB DEVICES<\/strong>\u00a0tab)<\/li>\n
    2. Choose your subscription, resource group, and the closest deploy location to you.<\/li>\n
    3. For\u00a0Pricing and scale tier, select the\u00a0F1 – Free<\/strong>\u00a0tier if it’s still available on your subscription.<\/li>\n
    4. Enter the name of your IoT Hub.<\/li>\n
    5. Wait a few minutes until the IoT Hub is created. you can see that your devices status become\u00a0No device in …<\/strong>.<\/li>\n<\/ol>\n

      \"create<\/p>\n

      <\/a>Register a device<\/h2>\n

      A device must\u00a0be registered\u00a0with your IoT hub before it can connect.<\/p>\n

        \n
      1. Click\u00a0… > Create Device<\/strong>\u00a0at\u00a0AZURE IOT HUB DEVICES<\/strong>\u00a0tab, or type\u00a0Azure IoT Hub: Create Device<\/strong>\u00a0in\u00a0Command Palette.<\/li>\n
      2. Enter device ID and press\u00a0Enter<\/strong>.<\/li>\n
      3. Wait a few seconds until the new device is created.<\/li>\n<\/ol>\n

        \"create<\/p>\n

        Say Hello to IoT Hub (Send D2C message)<\/h2>\n

        Right-click your device and select\u00a0Send D2C message to IoT Hub<\/strong>, then enter the message, results will be shown in\u00a0OUTPUT > Azure IoT Toolkit<\/strong>\u00a0view. Your ‘Hello World’ is sent to Azure IoT Hub!<\/p>\n

        \"send<\/p>\n

        Monitor IoT Hub D2C message in VS Code<\/h2>\n

        While you could send message to your IoT Hub, it is also possible to\u00a0monitor those message\u00a0in VS Code.<\/p>\n

          \n
        1. Right-click your device and select\u00a0Start Monitoring D2C Message<\/strong>.<\/li>\n<\/ol>\n

          \"start<\/p>\n

            \n
          1. The monitored messages will be shown in\u00a0OUTPUT > Azure IoT Toolkit<\/strong>\u00a0view.<\/li>\n
          2. To stop monitoring, right-click the\u00a0OUTPUT<\/strong>\u00a0view and select\u00a0Stop Monitoring D2C Message<\/strong>.<\/li>\n<\/ol>\n

            \"stop<\/p>\n

            Is that cool? You could send and receive messages for Azure IoT Hub very easily in VS Code. Is that all? Not yet! Actually, you could use Azure IoT Toolkit extension<\/a> to do lots of things when you develop with Azure IoT Hub! Checkout with our Wiki Page<\/a> to see the full features and tutorials. Azure IoT Toolkit makes your Azure IoT development easier.<\/p>\n
