Example of AWS IoT connection and Web Dashboard thru STM32 Nucleo evaluation board and mbed OS.
Dependencies: X_NUCLEO_IKS01A1 mbed FP MQTTPacket DnsQuery ATParser
Introduction
The demo is aimed to STM32 Nucleo board with WiFi and sensors expansions. The board is a "thing" for the AWS IoT service. It updates IoT service shadow with sensors data every second and checks subscription messages.
Hardware Configuration
- NUCLEO-F401RE - Nucleo Development Board
- X-NUCLEO-IDW01M1 - Wi-Fi expansion board for STM32 Nucleo
- X-NUCLEO-IKS01A1 - Motion MEMS and environmental sensor expansion board for STM32 Nucleo
Software Configuration
- Import this Project to mbed online compiler
- Find the next part of code in main.cpp file ...
WiFi network credential
#include "mbed.h" // WiFi network credential #define SSID "" // Network must be visible otherwise it can't connect #define PASSW "" #error "Wifi SSID & password empty"
- ... And set it to your Network Name and Password. Do not forget to remove "#error" pragma line.
Information
Nucleo WiFi module is not the same as your smartphone or laptope - it is based on demo board. To avoid connection problems:
- Place Nucleo as close to WiFi hot spot as possible. Or...
- Turn on mobile hot spot in your laptop as close to the device as possible.
- Make sure that hot spot permits 2.4 GHz band communications
- Setup BackEnd and store certificates using this backend setup instruction
- Find AWS_IOT_MQTT_HOST define and change it to HTTPS point mentioned in your AWS IoT thing properties named "interact"
#define AWS_IOT_MQTT_HOST "xxxxxxxxxx.iot.us-east-1.amazonaws.com" //Use your own host.
- Find the certificate defines clientCRT and clientKey in main.cpp file and change it to ones provided by Amazon.

Build and Check
- Plugin your board to USB of your PC. USB Disk Drive and USB COM Port should appear in your system.
- Open any Serial Console, connect it to your USB Serial Port and setup speed equal to 115200.
- Compile this Project and save .bin file to USB Disk Drive
- After board reset you should see next log in serial console:

Information
Device connection state might be checked by Green Led on the board. Green light means that device is connected and transferring data to cloud.
- Configure and start your dashboard using instruction and corresponding sources from github
- Use Blue button to set up markers to charts.
- Use AWS IoT console MQTT Client to test device subscription to "Nucleo/test". Just publish any message to this topic and serial port output.
- PROFIT!
