Azure IoT Central CircuitPython library

This library is a CircuitPython implementation of a third party Azure IoT Central SDK.

The original implementation for Python and Micropython is here: github.com/obastemur/iot_client

Supported boards

You will need an Adafruit board with WiFi connectivity via an ESP32 chip, either on-board or using a separate board. This has been tested using:

• Adafruit PyPortal
• AdaFruit PyBadge with an Airlift FeatherWing

Usage

• Create an Azure IoT Central application, with a device template and a device. You can learn how to do this in the Azure IoT Central docs. This application will need:

  • A device template with an interface containing:

    • A telemetry value called value

    • A Command called command

  • A view for the device showing the value of value as well as a way to run the command

  • A single device using this template

• Download the latest version of the Adafruit CircuitPython libraries from the releases page

• Copy the following to the lib folder on your CircuitPython device

  Name	Type
  neopixel.mpy	File
  adafruit_minimqtt.mpy	File
  adafruit_logging.mpy	File
  adafruit_binascii.mpy	File
  adafruit_requests.mpy	File
  adafruit_ntp.mpy	File
  adafruit_hashlib	Folder
  adafruit_esp32spi	Folder
  adafruit_bus_device	Folder

• Copy the code from this repo to the device

• Edit 'secrets.py` to include your WiFi SSID and password, as well as the ID Scope, Device ID and Key for your device

• The device will reboot, connect to WiFi and connect to Azure IoT Central

• Check the Azure IoT Central app, you will see random numbers being sent fot value.

• Run the command command to toggle a NeoPixel on the board on and off.
