5 Running the Example

  1. Create a new project in MPLAB® X IDE (for ex: ATmega4808)
  2. Open MCC by clicking Tools→ Embedded→ MPLAB® Code Configurator or click on the MCC icon
  3. Navigate to Versions[MCC] → MPLAB® Code Configurator (Plugin) → Libraries → Microchip Technology, Inc. → AVR-IoT AWS Sensor Node. Check the version of AVR IoT Sensor Node to ensure selection of library version 1.0.1. If any other version is selected, double click on Library version 1.0.1.
  4. In the Device Resources panel navigate to Internet of Things → Examples → AVR-IoT AWS Sensor Node
  5. Double click on AVR-IoT Sensor Node to add this to the Project Resources panel
  6. In the Project Resources panel navigate to Internet of Things → Examples → AVR-IoT AWS Sensor Node
  7. Ensure AVR-IoT AWS Sensor Node is selected
  8. AWS IoT Core
    • The firmware uses host endpoint as an entry point for an AWS web service.
    • Default Endpoint: The AVR IoT AWS Sensor Node uses the endpoint of Microchip's AWS account by default. This default endpoint is stored in WINC15XX memory. Use the IoT Provisioning Tool to permanently modify the default endpoint URL.
    • Custom Endpoint: Checking the 'Cloud Configuration → Use custom endpoint URL' option in the GUI will allow the application to use a custom endpoint. Enter the custom values for modifying the endpoint URL in the respective sections. However, this will change the AWS endpoint URL only at run-time. Use the IoT Provisioning Tool to permanently change the default endpoint URL in the WINC15XX memory.
