FreeRTOS demo application


This page refers to the Amazon-FreeRTOS repository which is deprecated. We recommend that you start here when you create a new project. If you already have an existing FreeRTOS project based on the now deprecated Amazon-FreeRTOS repository, see the Amazon-FreeRTOS Github Repository Migration Guide.

The demo application in this tutorial is the coreMQTT Agent demo defined in the freertos/demos/coreMQTT_Agent/mqtt_agent_task.c file. It uses the coreMQTT library to connect to the Amazon Cloud and then periodically publish messages to an MQTT topic hosted by the Amazon IoT MQTT broker.

Only a single FreeRTOS demo application can run at a time. When you build a FreeRTOS demo project, the first demo enabled in the freertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h header file is the application that runs. For this tutorial, you do not need to enable or disable any demos. The coreMQTT Agent demo is enabled by default.
