IoT Hub Feather M0 WiFi Client application

This repo contains the source code to help you get familiar with Azure IoT using the Azure IoT Adafruit Feather M0 WiFi Starter Kit. You will find the lesson-based tutorials on Azure.com.

This repo contains an arduino application that runs on board Feather M0 WiFi with a BME280 temperature&humidity sensor, and then sends these data to your IoT hub. At the same time, this application receives Cloud-to-Device message from your IoT hub, and takes actions according to the C2D command.

Install board with your Arduino IDE

Follow this page to install the board managers for your M0 WiFi.

Install libraries

Install the following libraries from Sketch -> Include library -> Manage libraries

• Adafruit_WINC1500
• RTCZero
• NTPClient
• AzureIoTHub
• AzureIoTUtility
• AzureIoTProtocol_HTTP
• ArduinoJson
• Adafruit BME280 Library
• Adafruit Unified Sensor

Connect your sensor with your board

Connect with a physical BME280 sensor

You can follow the image to connect your BME280 with your Feather M0 WiFi.

DON'T HAVE A PHYSICAL BME280?

You can use the application to simulate temperature&humidity data and send to your IoT hub. 1. Open the app/config.h file. 2. Change the SIMULATED_DATA value from false to true.

Configure and run sample application

Upload the app.ino to your board.

Input your credential information

After you successfully upload the code to your board. You will see some prompt, input your credential information according to the prompts.

Send Cloud-to-Device command

You can send a C2D message to your device. You can see the device prints out the message and blinks once receiving the message.
