Registering a Device with Azure IoT Hub

1. Access the CLI by using Azure Cloud Shell, logging in with the credentials provided in the lab.

2. Click the Cloud Shell icon (>_) in the upper-right of the screen.

3. Click Bash.

4. Click Show advanced settings, and set the following values:

   • Subscription: Leave default
   • Resource group: Use Existing
   • Cloud Shell region: Use the same region as your lab provided storage account.
   • Storage account: Use existing
   • File share: Create new, and enter cloudshell

5. Click Create storage.

6. Install the Azure IoT extension for CLI:

   az extension add --name azure-iot
   

7. Register the device (XXXXX is the five-character suffix for the lab resources):

   az iot hub device-identity create --device-id IoTDevice1 --hub-name iothub-XXXXX
   

8. Obtain the connection string for the device (XXXXX is the five-character suffix for the lab resources):

   az iot hub device-identity connection-string show --hub-name iothub-XXXXX --device-id IoTDevice1 --output table
   

9. Copy this connection string to your clipboard.

1. Access the simulator at https://azure-samples.github.io/raspberry-pi-web-simulator/.

2. Change the following line (line 15), replacing the text between the single quotes with the connection string you copied in the previous objective:

   const connectionString = '[Your IoT hub device connection string]';
   

In the Raspberry Pi Azure IoT Online Simulator, click Run. If the previous objective was performed correctly, the "LED" light will blink, and you should see messages from the "device" being sent to the IoT hub, like so:
