Azure IoT Hub SDKs

There are two categories of software development kits (SDKs) for working with IoT Hub:

  • IoT Hub Service SDKs enable you to build backend applications to manage your IoT hub, and optionally send messages, schedule jobs, invoke direct methods, or send desired property updates to your IoT devices or modules.

  • IoT Hub Device SDKs enable you to build apps that run on your IoT devices using device client or module client. These apps send telemetry to your IoT hub, and optionally receive messages, job, method, or twin updates from your IoT hub. You can use these SDKs to build device apps that use Azure IoT Plug and Play conventions and models to advertise their capabilities to IoT Plug and Play-enabled applications. You can also use module client to author modules for Azure IoT Edge runtime.

In addition, we also provide a set of SDKs for working with the Device Provisioning Service.

  • Provisioning Device SDKs enable you to build apps that run on your IoT devices to communicate with the Device Provisioning Service.

  • Provisioning Service SDKs enable you to build backend applications to manage your enrollments in the Device Provisioning Service.

Learn more about the IoT Hub Device SDKS in the IoT Device Development Documentation.

SDK and hardware compatibility

For more information about choosing a device SDK, see Overview of Azure IoT Device SDKs.

For more information about SDK compatibility with specific hardware devices, see the Azure Certified for IoT device catalog or individual repository.

Note

Some of the features mentioned in this article, like cloud-to-device messaging, device twins, and device management, are only available in the standard tier of IoT Hub. For more information about the basic and standard IoT Hub tiers, see How to choose the right IoT Hub tier.
