This repository contains the following:
- Azure IoT Hub Device SDK: to connect client devices to Azure IoT Hub
- Azure IoT Hub Service SDK: enables developing back-end applications for Azure IoT
- Node-RED node for Azure IoT: enables creating Node-RED flows that connect with Azure IoT Hub
To find SDKs in other languages for Azure IoT, please refer to the azure-iot-sdks repository.
Visit Azure IoT Dev Center to learn more about developing applications for Azure IoT.
Devices and data sources in an IoT solution can range from a simple network-connected sensor to a powerful, standalone computing device. Devices may have limited processing capability, memory, communication bandwidth, and communication protocol support. The IoT device SDKs enable you to implement client applications for a wide variety of devices. The API reference documentation is here.
-
Using npm packages: the simplest way to use the Azure IoT SDKs for Node.js to develop device apps is to leverage the npm packages:
-
Working with the SDKs code: if you are working with the SDK's code to modify it or to contribute changes, then you can clone the repository and build the libraries following these instructions.
Within the repository, you can find various types of simple samples that can help you get started.
If you encounter any bugs, have suggestions for new features or if you would like to become an active contributor to this project please follow the instructions provided in the contribution guidelines.
If you are having issues using one of the packages or using the Azure IoT Hub service that go beyond simple bug fixes or help requests that would be dealt within the issues section of this project, the Microsoft Customer Support team will try and help out on a best effort basis. To engage Microsoft support, you can create a support ticket directly from the Azure portal. Escalated support requests for Azure IoT Hub SDK's development questions will only be available Monday thru Friday during normal coverage hours of 6 a.m. to 6 p.m. PST. Here is what you can expect Microsoft Support to be able to help with:
- Client SDKs issues: If you are trying to compile and run the libraries on a supported platform, the Support team will be able to assist with troubleshooting or questions related to compiler issues and communications to and from the IoT Hub. They will also try to assist with questions related to porting to an unsupported platform, but will be limited in how much assistance can be provided. The team will be limited with trouble-shooting the hardware device itself or drivers and or specific properties on that device.
- IoT Hub / Connectivity Issues: Communication from the device client to the Azure IoT Hub service and communication from the Azure IoT Hub service to the client. Or any other issues specifically related to the Azure IoT Hub.
- Portal Issues: Issues related to the portal, that includes access, security, dashboard, devices, Alarms, Usage, Settings and Actions.
- REST/API Issues: Using the IoT Hub REST/APIs that are documented in the documentation.
The project is using LTS branches to allow users that do not need the latest and greatest features to be shielded from unwanted changes.
An LTS branch will be created every 6 months. The lifetime of an LTS branch is currently 1 year. LTS branches receive all bug fixes that fall in one of these categories:
- security bugfixes
- critical bugfixes (crashes, memory leaks, etc.)
No new features or improvements will be picked up on LTS branches.
LTS branches are named lts_mm_yyyy, where mm and yyyy are the month and year when the branch was created. An example of such a branch is lts_03_2017.
This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact opencode@microsoft.com with any additional questions or comments.
