Creating a Firmware Update

Now you can create an updated firmware image to install using the OTA Update service. In these steps, we just update the firmware version of the OTA demo application. Because the OTA demo displays the version of the firmware on device reset, we can use the displayed version to verify the update was successful.

To create an updated version of the firmware

  1. Open the aws_demos project in the MPLAB X IDE.

  2. Open aws_demos/application_code/common_demos/include/aws_application_version.h and set APP_VERSION_BUILD to 1.

  3. Rebuild the aws_demos project.
