OpenThread released by Nest is an open-source implementation of Thread®. Nest has released OpenThread to make the networking technology used in Nest products more broadly available to developers, in order to accelerate the development of products for the connected home.
With a narrow platform abstraction layer and a small memory footprint, OpenThread is highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs.
Thread® is an IPv6-based networking protocol designed for low-power Internet of Things devices in an IEEE 802.15.4-2006 wireless mesh network, commonly called a Wireless Personal Area Network (WPAN). Thread is independent of other 802.15.4 mesh networking protocols, such a ZigBee, Z-Wave, and Bluetooth LE.
