Matter

Matter (formerly Project Connected Home over IP or Project CHIP) is an open-source application layer that aims at creating a unified communication standard across smart home devices, mobile applications, and cloud services. It supports a wide range of existing technologies, including Wi-Fi®, Thread, and Bluetooth® LE, and uses IPv6-based transport protocols like TCP and UDP to ensure connectivity between different kinds of networks.

To learn more about the solution, see the Matter Add-on documentation. For source code, refer to the ncs-matter add-on repository.

In nRF Connect SDK v3.4.0 and earlier, Matter support is integrated in the SDK. In later nRF Connect SDK releases, Matter 1.6 support and Matter samples are available through the Matter Add-on.

See Migrating Matter projects from sdk-nrf to Matter add-on for migration instructions.
