What is OpenThread?

OpenThread released by Google is

• an open-source implementation of the Thread networking protocol.** Google Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home.

• OS and platform agnostic**, with a narrow platform abstraction layer and a small memory footprint, making it highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs.

• a Thread Certified Component**, implementing all features defined in the Thread 1.1.1 specification, including all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support.

More information about Thread can be found at threadgroup.org. Thread is a registered trademark of the Thread Group, Inc.
