Summary

The tutorial will provide step by step instructions for the following:

• Configuring Azure IoT Hub to allow client connections to a deployed IoT Edge Hub
• Connecting Azure Injector to the IoT Edge Hub
• Publishing data from Azure Injector to Azure IoT Edge Hub and viewing the data

Tutorial

There are two primary ways to connect to an Azure Edge Hub via MQTT from an MQTT client. These are 'module' or 'device' connections. A module connection typically involves an application deployed as a docker container that runs in Azure Edge. This is the preferred way of connecting the Azure Injector module to Azure Edge Hub. This tutorial will use this method for connecting to Azure IoT Edge.

After completing the prerequisites, you should have an IoT Edge Device as shown below. In this example, it has a name of 'My-IoT-Edge' and is listed under the IoT Edge devices.

Note this shows an error that the '417 - The device's deployment configuration is not set'. This can be fixed by creating a deployment configuration for this Azure Edge Device. Begin by clicking the Device in the Azure Portal. After doing so, you should see something similar to what is shown below.

Now click 'Set modules' in the upper left corner. That will open the following page.
