OpenThread is an open-source implementation of the Thread networking protocol. 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.
The Thread specification defines an IPv6-based reliable, secure and low-power wireless device-to-device communication protocol for home applications. More information about Thread can be found on threadgroup.org.
OpenThread implements all Thread networking layers including IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, and Mesh Routing.
Nest, along with ARM, Atmel, a subsidiary of Microchip Technology, Dialog Semiconductor, Microsoft Corporation, Nordic Semiconductor, Qualcomm Technologies, Inc. (a subsidiary of Qualcomm Incorporated), and Texas Instruments Incorporated are contributing to the ongoing development of OpenThread.
The easiest way to get started is to run the CLI example in /examples/apps/cli. See the CLI example README for more details.
In the repo you'll find the following directories and files:
| File/Folder | Provides |
