IoT Hub XinaBox CW01 Client application

This repo contains the source code to help you get familiar with Azure IoT using the XK10 Iot starter kit. You will find the CW01 Get Started.

This repo contains an arduino application that runs on board the XinaBox CW01 with a xChip SW01(BME280) weather 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.

Create your Azure IoT hub

Follow this page to prepare your Azure IoT hub and register your device.

Install board with your Arduino IDE

1. Start Arduino and open Preferences window.
2. Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
3. Open Boards Manager from Tools > Board menu and install esp8266 platform 2.2.0 or later
4. Select your ESP8266 board from Tools > Board menu after installation

Install libraries

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

• AzureIoTHub
• AzureIoTUtility
• AzureIoTProtocol_MQTT
• ArduinoJson
• SW01
• xCore

Connect your sensor with your board

Connect with a physical SW01(BME280)

You can follow the image to connect your SW01 with your XinaBox CW01.

DON'T HAVE A PHYSICAL SW01(BME280)?

You can use the application to simulate 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.

Send Device Method command

You can send start or stop device method command to your xChip CW)1 to start/stop sending message to your IoT hub.
