How to Quick Connect STM32U5 to Azure IoT Central

A step-by-step guide to connect and publish real B-U585I-IOT02A Discovery Kit sensor data to a free Azure IoT Central Application.STM32U5 Azure Quick Connect - Getting Started Guide
 
STM32U5 Azure Quick Connect is the fastest way to get your B-U585I-IOT02A Discovery Kit up and running with Azure IoT Central and Plug and Play. This demonstration reduces software requirements, configuration steps, and start-up time to show how easy it is to leverage IoT solutions with STM32 microcontrollers and Azure IoT.  
Goal: Connect the B-U585I-IOT02A Discovery Kit to a free Azure IoT Central Application and publish sensor data (as seen below) within a matter of minutes.

 

1. Software Requirements

• Python 3
  • Ensure install includes pip and python is added to path
• PySerial
  • Install using pip
• STM32U5 Azure Quick Connect Package:
  • Windows
  • MacOS
  • Linux

2. Hardware Requirements 

• B-U585I-IOT02A Discovery Kit
  • 
• Micro-USB Cable
  • 

3. Create an Azure IoT Central Application

Click the Quick Connect Application Template and login with a valid Microsoft account (no subscription required) 
After choosing a unique Application name, URL, and Pricing plan click ‘Create’

 

4. Add A Device to the Central Application

In the menu on the left select ‘Devices’
 
Select ‘New’ to add a new device

Enter a unique ‘Device name’ and ‘Device ID’ 
Choose ‘B-U585I-IOT02A IoT Node 2 discovery kit.’ as the Device Template.
Make sure ‘Simulate this device’ is not selected
And select ‘Create’

Your new device should now populate in the devices tab

 

5. Collect Connection Credentials

Click on the ‘Device Name’ of the device you want to connect to

Click ‘Connect’

Here you can view all the required device Connection Credentials

In File Explorer Navigate to STM32U5_Azure_QuickConnect  and open Config.txt

Enter the Wi-Fi SSID and Password for your 2.4Ghz network
Copy and Paste the ID Scope, Device ID, and Primary Key into this file and save.

 

6. Run Quick Connect Executable

Connect your Discovery Kit using the Micro-USB cable as pictured below

Ensure that you downloaded the correct STM32U5_Azure_QuickConnect package for you operating system above and run the STM32U5_AZURE_QuickConnect.exe

Script logs can be seen in the window:

 

8. Monitor Device Activity

Navigate back to your device in your central application and you can see a summary of the incoming data

Under ‘Raw data’ specific MQTT messages can be viewed
