Step 7: Set-up and Run Demo

The ThingWorx Azure IoT Connector download includes a Java application that simulates a device connecting to your Azure IoT Hub. A ThingTemplate is also included and can be imported into ThingWorx.

Import Demo Templates

1. In ThingWorx Composer, click Import/Export menu, then click From File and browse to ../demo/edgedevice- demo/platform/entities/CPUDemo_AllEntities.xml
   
   

   
2. Click Import then click Close when the import successful message is displayed.
3. Create a new Thing using the imported template azureDemo1, enter a name for your Thing and click Save.
   
   NOTE: You will enter this name in the demo config file in the next step.
   
   

Configure Demo Application

1. In the ../demo/edge-device-demo/conf subdirectory, open the edge-device.conf file with a text editor.
2. Edit the deviceId to be the name of the Thing you created in step 3.
3. Edit the iotHubHostName to use the name of your hub plus the domain: azure-devices.net. For example, sample-iot-hub.azuredevices.net.
4. Edit the registryPolicyKey property to use the Primary Key for the registryReadWrite policy in the Azure IoT Hub.

Below is an example configuration:

azure-edge-device {
  deviceId = "alstestedgething"
  iotHubHostname = "alsiot.azure-devices.net"
  registryPolicyName = "registryReadWrite"
  registryPolicyKey = "pzXAi2nonYWsr3R7KVX9WuzV/1234567NZVTuScl/Kg=" }

 

Run Demo Script

1. Open a shell or Command Prompt, set the EDGE_DEVICE_DEMO_OPTS environment variable to refer to the file you just edited:
   • Linux - export EDGE_DEVICE_DEMO_OPTS="-Dconfig.file=../conf/edge-device.conf"
   • Windows - set EDGE_DEVICE_DEMO_OPTS="-Dconfig.file=../conf/edge-device.conf"
2. Launch the demo from the ../demo/edge-device-demo/bin subdirectory, using the edge-device-demo command.
3. Return to the ThingWorx Composer and open the Properties page of the Azure Thing that you created previously.
4. Click the refresh button to see the properties change every five seconds.
5. Open the azure-iot-demo Mashup and view the Load Average and CPU gauges, and the increases in the values of the Cycle and Uptime fields.
   
   NOTE: If the edgedevice-demo is running on Windows, the Load Average does not register.
   
   

Step 8: Next Steps

Congratulations! You've successfully completed the Connect Azure IoT Hub to ThingWorx Quickstart. By following the steps in this lesson, you imported a device created in Azure into ThingWorx and saw how data from an Azure device could be used in a ThingWorx Mashup.
