There are two categories of software development kits (SDKs) for working with IoT Hub:
-
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 also use module client to author modules for Azure IoT Edge runtime.
-
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.
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.

Supported platforms for the SDKs can be found in Azure IoT SDKs Platform Support.
For more information about SDK compatibility with specific hardware devices, see the Azure Certified for IoT device catalog or individual repository.
The Microsoft Azure IoT device SDKs contain code that facilitates building applications that connect to and are managed by Azure IoT Hub services.

Azure IoT Hub service SDK for C:
The Azure IoT Service SDK for C is no longer under active development. We will continue to fix critical bugs such as crashes, data corruption, and security vulnerabilities. We will NOT add any new feature or fix bugs that are not critical, however.
Azure IoT Service SDK support is available in higher-level languages (C#, Java, Node, Python).
- Download from apt-get, MBED, Arduino IDE, or NuGet
- Source code
Azure IoT Hub service SDK for iOS:
Note
See the readme files in the GitHub repositories for information about using language and platform-specific package managers to install binaries and dependencies on your development machine.
The Microsoft Azure Provisioning SDKs enable you to provision devices to your IoT Hub using the Device Provisioning Service.
