Matter 1.0 in the nRF Connect SDK

Latest Nordic version of nRF Connect SDK offers developers support for all features of Matter over Thread version 1.0

Nordic Semiconductor announces that the release of the latest version of its SDK (Software Development Kit) nRF Connect brings developers support for all the features of version 1.0 of Matter over Thread. This support is tied to the formal adoption of the Matter specification version 1.0 by the Connectivity Standard Alliance (“the Alliance”). Matter is emerging as a breakthrough standard for smart home device interoperability.

“Nordic has played a major role in the Matter initiative from the very beginning, so we’re excited to introduce the nRF Connect SDK with full support for Matter over Thread, says Krzysztof Loska, technical product manager at Nordic. “This support is ready for Matter 1.0 adoption and enables developers to immediately jump into Matter over Thread development using Nordic’s nRF52840 and nRF5340 SoCs.

nRF Connect Software Development Kit

The nRF Connect Software Development Kit is Nordic’s scalable and unified development tool for building products based on the company’s nRF52 and nRF53 series system-on-chip (SoC), the system-in-package (SiP) of the nRF91 series as well as the all-new nRF7002 Wi-CI Fi 6 companion. nRF Connect SDK 2.1.0 includes the full Matter over Thread and adds experimental Matter over Wi-Fi support for the nRF5340 SoC in combination with the nRF7002 Companion integrated circuit.

The incorporation of Matter over Thread comes after Nordic was the first company to earn a Thread 1.3 certification badge for the nRF Connect SDK earlier this year. Thread 1.3 is a prerequisite for Matter over Thread and the certification can easily be inherited by enterprise customers for their own products.
Although nRF Connect SDK 2.1.0 is complete, it is marked as “experimental” because it was released before Matter 1.0 was officially adopted. Nordic will soon release an nRF Connect 2.1.X SDK to provide necessary bugfixes and small improvements in Matter over Thread and to remove experimental status. Customers can continue to use nRF Connect SDK 2.1.0 to comply with the Matter 1.0 specification after some minor manual updates. Matter over Wi-Fi will transition from experimental to full support when the nRF7002 enters volume production.

Matter is a connectivity standard that forms a common language to bring together disparate ecosystems and enables smart devices from different manufacturers to work in harmony. The standard uses a common application layer and data model that provides interoperability between devices allowing them to communicate with each other, regardless of the underlying network protocol or ecosystem. It is based on proven technologies on the market using Internet Protocol (IP). Matter works on the Wi-Fi, Thread and Ethernet network layers and uses Bluetooth LE for commissioning.

Today, Nordic customers are actively developing Matter-compliant devices using the company’s nRF52840 and nRF5340 systems-on-chip (SoCs), which support Thread and Bluetooth LE. The Wi-Fi 6 Companion nRF7002 IC also supports Matter. Recent examples, including Nordic customer products using the nRF52840 and nRF5340 SoCs, and Nordic using its Thingy:53 prototyping platform to run the Matter Weather Station app, have passed Matter test events and product validation events. Alliance Matter (SVE) specifications. This success proves the maturity and full compliance of Nordic products with the Matter 1.0 specification.

Nordic was recently elevated to the Alliance Board of Directors and added as a Promoter Member, the highest level of membership. These changes allow Nordic to further influence the development of Alliance standards, including Matter.
