OpenThread
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 Certified component
OpenThread implements all features defined in the Thread 1.1.1 Specification. This specification defines an IPv6-based reliable, secure, and low-power wireless device-to-device communication protocol for home applications.
Features
OpenThread implements 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.
Application services
- IPv6 configuration and raw data interface
- UDP sockets
- CoAP client and server
- DHCPv6 client and server
- DNSv6 client
Enhanced Features
- Child Supervision
- Inform Previous Parent on Reattach
- Jam Detection
- Periodic Parent Search
Border Router
- Web UI for configuration and management
- Thread Border Agent to support an External Commissioner
- NAT64 for connecting to IPv4 networks
- Thread interface driver using wpantund
How will you use OpenThread?
If you're interested in contributing to the ongoing development of OpenThread, then the OpenThread GitHub repository is for you. There you will find all the code, including information on how to contribute, our style guide, code of conduct, licensing, and much more.

If you want to use OpenThread in your own products or for personal deployment, check the options below.
Deploy a Thread network
Determine the hardware and platform design you wish to use to build and deploy your own Thread network. Add a Border Router to connect your Thread network to other network layers, such as Wi-Fi or Ethernet.
Develop applications on top of a Thread network
Use the API Reference as a guide to all application development. IPv6, UDP, CoAP, DHCPv6, DNSv6...it's all there.
Port OpenThread to a new hardware platform
Check out our Porting Guide, which walks you through all the steps necessary to port OpenThread to a new hardware platform.
Get Thread Certification for your OpenThread product
OpenThread can be used for certification by the Thread Group. As a Thread reference stack, OpenThread makes certification easy.

Bringing the internet to low-power IoT devices
OpenThread was at Google I/O 2018! Check out the video to watch our session, which
gives a brief overview of Thread and how developers can quickly build IoT
solutions using OpenThread.
I/O guide to Nest and OpenThread
Take a look inside the Nest IoT Sandbox display at Google I/O 2018, where we
showcased a number of OpenThread-supported developer platforms, the Thread Ready
Nest Secure system, and
other Nest products such as
Nest Hello and the
