OpenThread overview

OpenThread is a portable and flexible open-source implementation of the Thread networking protocol. It has been created by Google in active collaboration with Nordic Semiconductor, to accelerate the development of products for the connected home.

The Thread implementation in nRF Connect SDK is based on the OpenThread stack, which is integrated into Zephyr. You can find the OpenThread stack in ncs/modules/lib/openthread.

Among others, OpenThread has the following main advantages:

  • A narrow platform abstraction layer that makes the OpenThread platform-agnostic

  • Small memory footprint

  • Support for system-on-chip (SoC), network co-processor (NCP), and radio co-processor (RCP) designs

  • Official Thread certification
