Klika Tech / Mbed 2 deprecated Nucleo-AWS-IoT-mbed

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!
