**Important**  <a name="deprecation-message-demo"></a>
This demo is hosted on the Amazon-FreeRTOS repository which is deprecated. We recommend that you [start here](freertos-getting-started-modular.md) 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](github-repo-migration.md).

These demos can help you learn how to use the coreMQTT library.
