Azure IoT Hub

Azure IoT Hub extension is now a part of Azure IoT Tools extension pack. We highly recommend installing Azure IoT Tools extension pack, which makes it easy to discover and interact with Azure IoT Hub that power your IoT Edge and device applications. This extension pack can help you:

• Develop and connect your Azure IoT Applications to Azure. With this extension, you can interact with an Azure IoT Hub, manage connected devices, and enable distributed tracing for your Azure IoT applications.
• Develop and debug Certifies Azure IoT Devices (including MXChip IoT DevKit, ESP32, Raspberry Pi) to Azure. This extension pack makes it easy to code, build, deploy and debug your IoT applications with popular IoT development boards.
• Develop and deploy artificial intelligence and your custom logic to Azure IoT Edge. This extension pack makes it easy to code, build, deploy, and debug your IoT Edge applications.

Overview

Prerequisites

1. In Explorer of VS Code, click "Azure IoT Hub" in the bottom left corner.

2. Click "Set IoT Hub Connection String" in context menu.

3. An input box will pop up, then enter your IoT Hub Connection String (It is one-time configuration, and please make sure it is IoT Hub Connection String not Device Connection String. The format is HostName=<my-hub>.azure-devices.net;SharedAccessKeyName=<my-policy>;SharedAccessKey=<my-policy-key>).

4. The devices list will be shown.

Sign in to Azure

Instead of copying and pasting to set IoT Hub Connection String, you could sign in to Azure to select IoT Hub from your Azure Subscription.

1. Click "Select IoT Hub" in context menu.

2. If you have not signed in to Azure, a pop-up will show to let you sign in to Azure.
3. After you sign in, your Azure Subscription list will be shown, then select an Azure Subscription.
4. Your IoT Hub list will be shown, then select an IoT Hub.
5. The devices and endpoints list will be shown.

Device Provisioning Service Explorer

1. Open "Azure" view on the Activity Bar, and expand "IOT HUB DEVICE PROVISIONING SERVICE".

2. If you're not signed in, click "Sign in to Azure..." to sign in.

3. Expand one subscription to start exploring your device provisioning services.

Code Generation

Code Snippets

Trigger	Content
iotSendD2CMessage	Send D2C message to IoT Hub
iotMonitorD2CMessage	Monitor D2C message for IoT Hub
iotSendC2DMessage	Send C2D message to device
iotMonitorC2DMessage	Monitor C2D message from IoT Hub
iotCallDirectMethods	Send direct methods to device
iotReceiveDirectMethods	Receive direct methods from IoT Hub

After code snippet is created, you need to install corresponding npm package (e.g. azure-iot-device-mqtt) to run the code snippet. If you want to 'Run Code' directly, you need to install Code Runner.

Configuration

IoT Hub Consumer Group (default is "$Default"):

{
    "azure-iot-toolkit.iotHubConsumerGroup": "$Default"
}

The time span (in minutes) of monitoring D2C message before current time (default is 0):

{
    "azure-iot-toolkit.monitorD2CBeforeNowInMinutes": 0
}

Whether to show verbose info when monitoring messages (default is false):

{
    "azure-iot-toolkit.showVerboseMessage": false
}

Whether to stringify device-to-cloud messages (default is false):

{ 
    "azure-iot-toolkit.iotHubD2CMessageStringify": false
}

Whether to show IoT Hub info when IoT Hub Connection String is not set (default is true):

{ 
    "azure-iot-toolkit.showIoTHubInfo": true
}

Whether to enable auto refresh of tree view (default is false):

{ 
    "azure-iot-toolkit.treeViewAutoRefreshEnable": false
}

Time interval in seconds for tree view auto refresh, auto refresh has to be enabled for it to work. (default is 60):

{ 
    "azure-iot-toolkit.treeViewAutoRefreshIntervalInSeconds": 60
}
