IoT Hub Raspberry Pi 3 Client application
This repo contains the source code to help you get familiar with Azure IoT using the Microsoft IoT Pack for Raspberry Pi 3 Starter Kit. You will find the lesson-based tutorials on Azure.com.
This repo contains an arduino application that runs on Raspberry Pi 3 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.
Set up your Pi
Enable SSH on your Pi
Follow this page to enable SSH on your Pi.
Enable SPI on your Pi
Follow [this page]https://www.raspberrypi.org/documentation/configuration/raspi-config.md) to enable SPI on your Pi
Connect your sensor with your Pi
Connect with a physical BEM280 sensor and LED
You can follow the image to connect your BME280 and a LED with your Raspberry Pi 3.
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
config.h file. 2. Change the
SIMULATED_DATA value from
Running this sample
Install Azure IoT SDK
Install all packages by the following command:
grep -q -F 'deb http://ppa.launchpad.net/aziotsdklinux/ppa-azureiot/ubuntu vivid main' /etc/apt/sources.list || sudo sh -c "echo 'deb http://ppa.launchpad.net/aziotsdklinux/ppa-azureiot/ubuntu vivid main' >> /etc/apt/sources.list" grep -q -F 'deb-src http://ppa.launchpad.net/aziotsdklinux/ppa-azureiot/ubuntu vivid main' /etc/apt/sources.list || sudo sh -c "echo 'deb-src http://ppa.launchpad.net/aziotsdklinux/ppa-azureiot/ubuntu vivid main' >> /etc/apt/sources.list" sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys FDA6A393E4C2257F sudo apt-get update sudo apt-get install -y azure-iot-sdk-c-dev
Build the sample code
Build the sample code by the following command:
cmake . && make
Run your client application
Run the client application with root priviledge, and you also need provide your Azure IoT hub device connection string, note your connection should be quoted in the command.
sudo ./app '<your Azure IoT hub device connection string>'
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
stop device method command to your Pi to start/stop sending message to your IoT hub.
