Azure IoT Gateway SDK

IoT scenarios vary drastically between industries and even between customers within the same industry. The Azure IoT Gateway SDK lets you build IoT solutions tailored to your exact scenario. Connect new or existing devices, regardless of protocol. Process the data in an on-premises gateway using the language of your choice (Java, C#, Node.js, or C), before sending it to the cloud. Deploy the solution on hardware that meets your performance needs and runs the operating system of your choice.

In the image below an existing device has been connected to the cloud using edge intelligence. The on-premises gateway not only preforms protocol adaptation which allows the device to send data to the cloud, it also filters the data so that only the most important information is uploaded.

Using existing modules from the Azure IoT Gateway SDK ecosystem significantly reduces your development and maintenance costs. Running the gateway on-premises opens up all kinds of scenarios like communicating between devices in real time, operating your IoT solution with an intermittent cloud connection, or enforcing additional security requirements.

SDK Modules

The following modules are available in this repository:

Name Description
ble Represents a Bluetooth low energy (BLE) device connected to the gateway
hello_world Sends a "hello world" message periodically
identitymap Maps MAC addresses to IoT Hub device IDs/keys
iothub Sends/receives messages to/from mapped devices and IoT Hub
logger Writes received message content to a file
simulated_device Simulates a gateway-connected BLE device
azure_functions Sends message content to an Azure Function

Featured Modules

Other people are creating modules for the gateway SDK too! See the More information link for a module to find out how to get it, who supports it, etc.

We'd love to feature your module here! See our Contribution guidelines for more info.

Operating system compatibility

The SDK is designed to be used with a broad range of operating system platforms. The version of the Azure IoT Gateway SDK has been tested on the following operating systems:

  • Ubuntu 14.04
  • Ubuntu 15.10
  • Yocto Linux 3.0 on Intel Edison
  • Windows 10
  • Wind River 7.0

Hardware compatibility

The SDK is designed to be independent from hardware in addition to the operating system. Developers can power their gateways with hardware as constrained as a microcontroller to systems as powerful as a ruggedized server.

Directory structure

/doc

This folder contains general documentation for the SDK as well as step by step instructions for building and running the samples:

General documentation

  • Dev box setup contains instructions for configuring your machine to build the Azure IoT Gateway SDK as well as instructions for configuring your machine to build modules written in Java, Node.js, and .NET.

API documentation can be found here.

/samples

This folder contains all of the samples for the Azure IoT Gateway SDK. Samples are separated in their own folders. Step by step instructions for building and running each sample can be found in the README.md file in the root of each sample's folder.

Samples include:

  • Hello World - Learn the basic concepts of the Azure IoT Gateway SDK by creating a simple gateway that logs a hello world message to a file every 5 seconds.
  • Simulated Device Send data to IoTHub from a gateway using a simualted device instead of using a real device.
  • Real Device - Send data to IoTHub from a real device that could not connect to the cloud unless it connected through a gateway. This sample uses a Blueetooth Low Energy Texas Instruments SensorTag as the end device .

/modules

This folder contains all of the modules included with the Azure IoT Gateway SDK. Each module represents a specific piece of functionality that can be composed into an end to end gateway solution. Details on the implementation of each module can be found in each module's devdoc/ folder.

/core

This folder contains all of the core infrastructure necessary to create a gateway solution. In general, developers only need to use components in the core folder, not modify them. API documentation for core infrastructure can be found here. Details on the implementation of core components can be found in core/devdoc.

/build

This is the default folder that cmake will place the output from our build scripts. The developer always has the final say about the destinaiton of build output by creating a folder, navigating to it, and then running cmake from there. Detailed instructions are contained in each sample doc.
