Connect the B-U585I-IOT20A board to Azure IoT Hub

[Alnur ELBERIER]

Simple tutorial to connect the B-U585I-IOT20A Development kit to Azure IoT Hub.Introduction:
In this article, we connect the B-U5U5I-IOT20A discovery board to Azure IoT Hub. IoT Hub is a cloud-hosted application that allows you to communicate with your IoT devices, understand their state and keep them up to date.
                    
The B-U5U5I-IOT20A discovery board is a IoT development board composed of a low power microcontroller, a Wi-Fi Radio, and sensors such as temperature and humidity, a magnetometer, accelerometer, gyroscope, pressure, Time-of-Flight, and gesture-detection.
Requirements
General requirements:

• An active Azure subscription (click here to create one)
• X-CUBE-AZURE downloaded and extracted do your C:/ Drive

Hardware requirements:

• B-U5U5I-IOT20A discovery board
• Type-A to male Type-B Micro-USB cable
• 2.4GHz Wi-Fi Router (No Captive Portal)
• Windows PC

Software requirements (Installed via Quick Setup Script):

• STM32CubeProgrammer
• X-CUBE-AZURE
• Python with Pip
• Azure CLI
• Edge or Chrome

Procedure
Configure PowerShell:

1. Open PowerShell

 

2. Set execution policy

Set-ExecutionPolicy -ExecutionPolicy Unrestricted  -Scope CurrentUser
 

 

3. Enter ‘y’ to accept the execution policy changes

Install the dependencies:

1. cd C:\STM32CubeExpansion_Cloud_AZURE_V2.2.0\Projects\B-U585I-IOT02A\Applications\TFM_Azure_IoT\AzureScripts\STM32U5_AZURE_QuickSetup
   Navigate to the directory containing setup material

 

2. Rename-Item .\STM32U5_AZURE_QuickSetup.ps1.txt .\STM32U5_AZURE_QuickSetup.ps1
   Rename Quick Setup script

 

3. Run the setup script. The following command programmatically installs all the required software.

.\STM32U5_AZURE_QuickSetup.ps1
 

Run The Quick Connect:
The Quick Connect script programmatically configures both the cloud and the discovery kit. After a successful execution of the script, the device will be provisioned with Azure IoT hub and communicating telemetry data to the cloud. \
 

1. cd C:\STM32CubeExpansion_Cloud_AZURE_V2.2.0\Projects\B-U585I-IOT02A\Applications\TFM_Azure_IoT\AzureScripts
   Navigate into correct working directory:

 

2. Run the script with -i argument:

Python .\STM32U5_AZ_IotHub_QC.py -i

     
 

3. Enter your Configuration Credentials:

 

4. Login to your Azure Account:

 

5. Monitor Script execution
