Overview

Demo for showing how to use the Device Shadow library's API.

Before building the example application select Wi-Fi module macro in the app_config.h. (see #define WIFI_BOARD). For more information about Wi-Fi module connection see: readme_modules.txt Getting started guide on supported modules configuration: https://www.nxp.com/document/guide/getting-started-with-nxp-wi-fi-modules-using-i-mx-rt-platform:GS-WIFI-MODULES-IMXRT-PLATFORM

Board settings

Prepare the Demo

Before running the demo it is need to configure AWS IoT Console and update some of project files:

1. Create AWS Account: https://console.aws.amazon.com/console/home

2. Configure device in the AWS IoT Console base on this guide: https://docs.aws.amazon.com/iot/latest/developerguide/create-iot-resources.html

   Make note of example's "Thing name" and "REST API endpoint". These strings need to be set in the "aws_clientcredential.h". Example: #define clientcredentialMQTT_BROKER_ENDPOINT "abcdefgh123456.iot.us-west-2.amazonaws.com" #define clientcredentialIOT_THING_NAME "MyExample"

   Device certificate and private key needs to be opened in text editor and its content copied into the "aws_clientcredential_keys.h". Note: be sure to add " at the beginning of a line and \n"\ on every line break. Example: #define keyCLIENT_CERTIFICATE_PEM NULL

   Needs to be changed to:
   
   #define keyCLIENT_CERTIFICATE_PEM "-----BEGIN CERTIFICATE-----\n"\
   "MIIDWTCCAkGgAwIBAgIUfmv3zA+JULlMOxmz+upkAzhEkQ0wDQYJKoZIhvcNAQEL\n"\
   .
   .
   .
   "mepuT3lKmD0jZupsQ9vLQOA09rMjVMd0YPmI9ozvvWqLpjVvNTKVhsf/3slM\n"\
   "-----END CERTIFICATE-----\n"
   

   In the same way update "keyCLIENT_PRIVATE_KEY_PEM" with content of private key file.

   Files "aws_clientcredential.h" and "aws_clientcredential_keys.h" are located in project folder.

3. This demo needs Wi-Fi network with internet access. Update these macros in "aws_clientcredential.h" based on your Wi-Fi network configuration: #define clientcredentialWIFI_SSID "Paste Wi-Fi SSID here." #define clientcredentialWIFI_PASSWORD "Paste Wi-Fi password here."

4. Open example's project and build it.

5. Connect a USB cable between the PC host and the OpenSDA port on the target board.

6. Download the program to the target board with the CMSIS-DAP or J-Link debugger.

7. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

8. Open a serial terminal on PC for serial device with these settings:

   • 115200 baud rate
   • 8 data bits
   • No parity
   • One stop bit
   • No flow control

Running the demo

The log below shows the output of the demo in the terminal window. The log can be different based on your Wi-Fi network configuration.
