This document describes how to create a program that uses the azure-iot-sdk-c-dev package on Ubuntu versions 15.04 and 15.10. The package contains the binaries you need to build an IoT Hub client application using C. The document describes how to install the package using apt-get and then build an application using CMake.

“E: Unable to locate package update” when I try to update my system, why? Ask Question Asked 6 years, 4 months ago. Active 4 years, 3 months ago. Mar 28, 2018 SDKs for a variety of languages and platforms that help connect devices to Microsoft Azure IoT services - Azure/azure-iot-sdks.

Before you start, make sure you have CMake, g++, and gcc installed on your development machine:

Update and install the azure-iot-sdk-c-dev package on your machine

Complete the following steps to install the AzureIoT binaries on your development machine:

1. Add the AzureIoT repository to the machine:

2. Install the azure-iot-sdk-c-dev package

Create an application using CMake

The following steps outline how you can use CMake to build an IoT Hub client application after you have installed the azure-iot-sdk-c-dev package on your development machine.

1. Create a CMakeLists.txt file for the application. The example shown here assumes you are using the serializer module in your code, that your application uses the AMQP protocol, and that your source code is contained in the files sample.c, sample.h, and main.c. You can add source files by changing the contents of the sample_application_c_files and sample_application_h_files sets. If you are not using the serializer module, you can omit it from target_link_libraries. If you are using a different protocol (such as MQTT) you need to change the content of target_link_libraries accordingly.

2. /seven-phases-spectrum-analyzer-vst-download.html. Create a directory that will store the make files that CMake creates and then run the cmake and make commands as follows:

Notes

The Azure IoT client libraries and their dependencies install to the following locations.

Libraries install in /usr/lib:

• libiothub_client_amqp_transport.a
• libiothub_client_http_transport.a
• libiothub_client_mqtt_transport.a
• libserializer.a
• libiothub_client.a

All azure-iot-sdk header files install in /usr/include/azureiot.

Dependencies install in /usr/lib:

• libumqtt.a
• libamqp.a
• libaziotsharedutil.a

To remove the azure-iot-sdk-c-dev package, run the following command:

This folder contains the following:

• The Azure IoT device SDK for C (prepackaged or to compile) to easily and securely connect devices to the Microsoft Azure IoT Hub service.
• Samples showing how to use the SDK

C Device SDK Features

• Sends event data to Azure IoT based services.
• Maps server commands to device functions.
• Buffers data when the network connection is down.
• Implements configurable retry logic.
• Batches messages to improve communication efficiency.
• Supports pluggable transport protocols: HTTPS, AMQP and MQTT.
• Supports pluggable serialization methods.

Azure IoT device SDK for C can be used with a broad range of OS platforms and devices.For a list of tested configurations click here.

Prepackaged C SDK for Platform Specific Development

apt-get packages for Linux devices

To make it simpler to use the IoT Hub device SDK on Linux, we have created apt-get packages that are published on the Launchpad platform.

At this point you can use the packages on Ubuntu 16.04 and 18.04 using the following CPU architectures: amd64, arm64, armhf and i386.

Here you can find a detailed guide on how to install the packages to develop your device application.

If you are working with a device running a Linux distribution not supporting these packages, then you will need to compile the SDK following the instructions below.

CocoaPods for Apple devices

The IoT Hub Device SDK is available as CocoaPods for Mac and iOS device development.Details for how to use the CocoaPods are available here.

Vcpkg packages for Windows devices

When developing for Windows devices, you can leverage the Vcpkg package manager in order to easily reference the Microsoft Azure IoTHub C SDK libraries in your projects.The Windows samples in this repository show how to use the azure-iot-sdk-c Vcpkg package along with its dependencies in your C project.To install Microsoft Azure IoTHub vcpkg, follow the instructions at Setup C SDK vcpkg for Windows development environment

mbed library for mbed Developer Workspace

For developers creating device applications on the mbed platform, we have published a library and samples that will get you started in minutes witH Azure IoT Hub. This library and the samples have been tested with the following boards:

• Freescale FRDMK64-F
• Renesas GR-PEACH
• SADE.IO GSM Gateway

To use the samples and the Azure IoT device SDK library in your mbed applications, here are the basic steps:

• Prepare your device as instructed by the device manufacturer to connect it to the mbed development environment
• In the mbed Developer Workspace click Import on the main menu. Then click the Click here to import from URL link next to the mbed globe logo.
• In the popup window, enter the link for the sample code you want to try (you can find Azure IoT Hub samples here).
• Adapt the code to use the right credentials for your device, and click Compile to generate the binary for your board.
• Download the binary to your device and run.

You can find detailed instructions for each of the tested devices in the Azure IoT device catalog:

Arduino IDE library

If you are developing on Arduino, you can leverage the Azure IoT library available in the Arduino IDE library manager.You can find the list of supported boards as well as the instructions for using the library on Arduino devices in the azure-iot-arduino GitHub repository directly.

Compiling the C Device SDK

Azure Iot Sdk Device Explorer

In order to compile the C SDK on your own, you will need to install a set of tools depending on the platform you are doing your development on and the one you are targeting. You will also need to clone the current repository.Detailed instructions can be found below for each platforms:

Samples

The repository contains a set of simple samples that will help you get started.You can find a list of these samples with instructions on how to run them here.In addition to the simple samples found in the current repository, you can find detailed instructions for the certified for Azure IoT devices in our online catalog
