Run a simple C sample on device running openSUSE

Introduction

About this document

This document describes how to connect devices running openSUSE with Azure IoT SDK. This multi-step process includes:

  • Configuring Azure IoT Hub
  • Registering your IoT device
  • Build and deploy Azure IoT SDK on device

Step 1: Prerequisites

You should have the following items ready before beginning the process:

Step 2: Prepare your Device

  • Open a PuTTY session and connect to the device.

Note: You can skip this step if you just want to build the sample application without running it.

Step 3: Build and Run the sample

## Setup the development environment

This section shows you how to set up a development environment for the Azure IoT device SDK for C on openSUSE.

  1. Clone this repository (azure-iot-sdks) to the machine you are using.

  2. Open a shell and navigate to the folder c/build_all/linux in your local copy of the repository.

  3. Run the setup_opensuse.sh script to install the prerequisite packages and the dependent libraries.

  4. Run the build.sh script.

This script builds the iothub_client and serializer libraries and their associated samples in a folder called "cmake" inside you home folder.

Note: you will not be able to run the samples until you configure them with a valid IoT Hub device connection string. For more information, see Run sample on Linux.

## Run the sample

  1. Open the file c/serializer/samples/simplesample_amqp/simplesample_amqp.c in a text editor.

  2. Locate the following code in the file:

    static const char* connectionString = "[device connection string]";

  3. Replace "[device connection string]" with the device connection string you noted earlier. Save the changes.

  4. Save your changes and build the samples. To build your sample you can run the build.sh script in the c/build_all/linux directory.

  5. Run the azure-iot-sdks/c/cmake/iotsdk_linux/serializer/samples/simplesample_amqp/simplesample_amqp sample application.

  6. See Manage IoT Hub to learn how to observe the messages IoT Hub receives from the simplesample_amqp application and how to send cloud-to-device messages to the simplesample_amqp application.
