• MCUXpresso 11.8.0

Hardware requirements

• Mini/micro USB cable
• LPCXpresso55s69 board
• Personal Computer
• Murata CMWC1ZZABR-107-EVB

Board settings

Plug the WiFi module to mikroBUS (P23, P24). 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. Open example's project and build it.

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

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

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

7. 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

8. During the runtime will be necessary to configure Wi-Fi module. Follow instructions in the terminal for Wi-Fi module configuration or resetting to provisioning mode. If the module is in provisioning mode, it will create micro-AP: SSID: Serial2Wifi Passphrase: nxp12345 Connect your PC or mobile phone to this Wi-Fi micro-AP, open address: http://192.168.10.1 in web browser, select "Provisioning" and then select WLAN for connection. Wi-Fi module stores the WLAN credentials and it will use them automatically for next connection.

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.
