Tutorial: Demonstrate MQTT message communication with the Amazon IoT Device Client
This tutorial demonstrates how the Amazon IoT Device Client can subscribe to and publish MQTT messages, which are commonly used in IoT solutions.
To start this tutorial:
-
Have your local host computer and Raspberry Pi configured as used in the previous section.
If you saved the microSD card image after installing the Amazon IoT Device Client, you can use a microSD card with that image with your Raspberry Pi.
-
If you have run this demo before, review Step 2: Cleaning up your Amazon Web Services account after building demos with the Amazon IoT Device Client to delete all Amazon IoT resources that you created in earlier runs to avoid duplicate resource errors.
This tutorial takes about 45 minutes to complete.
When you're finished with this topic:
-
You'll have demonstrated different ways that your IoT device can subscribe to MQTT messages from Amazon IoT and publish MQTT messages to Amazon IoT.
Required equipment:
-
Your local development and testing environment from the previous section
-
The Raspberry Pi that you used in the previous section
-
The microSD memory card from the Raspberry Pi that you used in the previous section
