Connect to AWS IoT & Send Data*

Image
• In this lab you are going to:  1. Update the firmware with:  a) The MQTT server address  b) Your device name   c) The Wi-Fi credentials  d) The device Certificate and the device Private Key 2. Load and run the firmware on the STM32L4 Discovery Kit IoT Node  3. Monitor your device activity ******************* let's go  1. Tera Term Configuration 2. Edit aws_clientcredential.h https://github.com/aws/amazon-freertos/blob/main/demos/include/aws_clientcredential.h 3. Configure Your AWS IoT Credentials 4. Open aws_demo IAR Project 5. Load and Run 6. Send Data to AWS • Now the application is up and running. The application will:       1. Connect to the Wi-Fi access point and acquire an IP address       2. Subscribe to the MQTT broker (AWS IoT)       3. Start sending/receive messages to/from the MQTT broker. The application generates an initial thing shadow docume...
