Matter development model and compatible ecosystems

The Matter stack is developed on the official Matter GitHub repository and is open-sourced.

The Matter stack implementation contains separation between platform-agnostic and platform-dependent functionality. The open-source implementation offers ports for several resource-constrained, embedded SoCs as well as POSIX-based platforms.

Matter strives for reusing technologies from market-proven solutions, such as Apple HomeKit or Google Weave. Wi-Fi and Thread are its main wireless connectivity protocols that offer seamless integration with other IPv6-based networks and are application-layer agnostic. Bluetooth® LE can be used for commissioning of the Matter accessories, and QR codes and NFC tags can be used to initiate the commissioning.

Matter in the nRF Connect SDK

The nRF Connect SDK provides full toolchain for Linux, macOS, and Windows, and is built on top of the Zephyr RTOS. It includes west for managing repositories, toolchain manager for managing toolchain, Kconfig for feature configuration, and Devicetree for board description. Finally, it integrates the OpenThread and Wi-Fi stacks, both of which can work in a multiprotocol scenario with the integrated Bluetooth® LE stack.

Nordic Semiconductor integrates the Matter stack in the nRF Connect SDK using a dedicated Matter fork. The official Matter repository is fetched into the fork and the fork is included in the nRF Connect SDK as a Zephyr module, including files deployed in the Matter documentation tab. The fork is maintained and verified as a part of the nRF Connect SDK release process as an OSS repository.

Compatibility with commercial ecosystems

One of the key features of the Matter protocol is the interoperability of different ecosystems it provides. Implementing support for Matter enables the Matter multiple fabrics feature and allows different vendor products to co-exist within the same Matter network.

The Matter stack in the nRF Connect SDK will work with any commercial Matter ecosystem as long as these ecosystems are compatible with the official Matter implementation (for example Apple Home, Google Home, Samsung SmartThings, or Amazon Alexa).

For an example of interoperability of some commercial ecosystems, see Testing with commercial Matter ecosystems.
