Azure IoT Hub extension for Visual Studio Code

  • Članak

Visual Studio Code (VS Code) lets you add extensions, such as languages, debuggers, and tools, to your VS Code installation to support your development workflow. The Azure IoT Hub extension for Visual Studio Code lets you add Azure IoT Hub support to your VS Code installation, so you can manage and interact with your IoT hubs, devices, and modules during development. The Azure IoT Hub extension is available from the Visual Studio Code Marketplace.

Note

Some of the features mentioned in this article, like cloud-to-device messaging, device twins, and device management, are only available in the standard tier of IoT Hub. For more information about the basic and standard/free IoT Hub tiers, see Choose the right IoT Hub tier for your solution.

The Azure Account extension also makes the Azure Cloud Shell service available in VS Code's integrated terminal.

Note

The Azure IoT Hub extension depends on the Azure Account extension for connectivity. You cannot uninstall the Azure Account extension without uninstalling the Azure IoT Hub extension.

Before the extension can interact with Azure IoT Hub, you must sign in to your Azure account from Visual Studio Code. You can use the Azure Account extension to:

  • Create an Azure account
  • Sign in and out of your Azure account
  • Filter the Azure subscriptions available to the Azure IoT Hub extension from your Azure account
  • Upload a file to your Azure Cloud Shell storage account

Follow these steps to sign into Azure and select your IoT hub from your Azure subscription:

  1. In the Explorer view of VS Code, expand the Azure IoT Hub section in the side bar.

  2. Select the ellipsis (…) button of the Azure IoT Hub section to display the action menu, and then select Select IoT Hub from the action menu.

  3. If you're not signed into Azure, a pop-up notification is shown in the bottom right corner to let you sign in to Azure. Select Sign In and follow the instructions to sign into Azure.

  4. Select your Azure subscription from the Select Subscription dropdown list.

  5. Select your IoT hub from the Select IoT Hub dropdown list.

  6. The devices for your IoT hub are retrieved from IoT Hub and shown under the Devices node in the Azure IoT Hub section of the side bar.

    Note

    You can also use a connection string to access your IoT hub, by selecting Set IoT Hub Connection String from the action menu and entering the iothubowner policy connection string for your IoT hub in the IoT Hub Connection String input box.

Once signed in, you can interact with your hubs, devices, and modules from either the Command Palette or the action menu in the Explorer view of VS Code.
