<div align="center"> <img src="./doc/images/Azure IoT Hub.png"> </div>Critical Upcoming Change Notice
All Azure IoT SDK users are advised to be aware of upcoming TLS certificate changes for Azure IoT Hub and Device Provisioning Service that will impact the SDK's ability to connect to these services. In October 2022, both services will migrate from the current Baltimore CyberTrust CA Root to the DigiCert Global G2 CA root. There will be a transition period beforehand where your IoT devices must have both the Baltimore and Digicert public certificates installed in their certificate store in order to prevent connectivity issues.
Devices with only the Baltimore public certificate installed will lose the ability to connect to Azure IoT hub and Device Provisioning Service in October 2022.
To prepare for this change, make sure your device's certificate store has both of these public certificates installed.
For a more in depth explanation as to why the IoT services are doing this, please see this article.
Components
The Azure IoT Node.js SDK enables developers to create IoT solutions written in Node.js for the Azure IoT platform. It is composed of the following client libraries:
- Device Client Library: to connect devices and IoT Edge modules to Azure IoT Hub. API Reference | README | Configuration Options
- Note: IoT Edge for Node.js is scoped to Linux containers & devices only. Learn more about using Linux containers for IoT edge on Windows devices.
- Provisioning Device Client Library: to connect devices to the Azure IoT Provisioning Service. API Reference
