Overview
========
The simple Shadow lightbulb example to illustrate how client application and things communicate with the Shadow service.
Toolchain supported
===================
- IAR embedded Workbench 9.20.2
- GCC ARM Embedded 10.3.1
- Keil MDK 5.36
- MCUXpresso 11.5.0
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/iot-sdk-setup.html
Make note of example's "Thing name" and "REST API endpoint". These strings need to be set in the "aws_clientcredential.h".
Example:
static const char clientcredentialMQTT_BROKER_ENDPOINT[] = "abcdefgh123456.iot.us-west-2.amazonaws.com";
#define clientcredentialIOT_THING_NAME "MyExample"
In the next step you will get the "device certificate" and the "primary key". The device certificate and private key needs to be opened in text editor and its content copied into the "aws_clientcredential_keys.h".
Or you can use the CertificateConfigurator.html (mcu-sdk-2.0\rtos\freertos\tools\certificate_configuration) to generate the "aws_clientcredential_keys.h".
Example:
#define keyCLIENT_CERTIFICATE_PEM "Paste client certificate here."
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 the private key array.
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.
