Matter

Standardized application layer foundation for connected things

About Matter

Matter, which began as Project CHIP (Connected Home over IP) was started in December 2019 by Amazon, Apple, Google, and others including Nordic Semiconductor. The goal is to agree on a unified application layer standard for connected things at home. Matter aims to make it easier for manufacturers to create secure and reliable solutions that are interoperable with the major smart home ecosystems like Apple’s Siri, Google’s Assistant, and Amazon’s Alexa.

Nordic is actively involved and heavily contributing to Matter. We are also a main contributor to the OpenThread stack. This combined with our knowledge and experience in Bluetooth Low Energy makes us the ideal partner to start developing your applications. 

Why is Matter needed?

The smart home market is relatively new and has an enormous potential. It has been growing slower than expected for the last years. A plethora of proprietary solutions using different protocols and application layers exist. This led to frustration with developers and consumers.

Matter steps in and provides a shared foundation on which to build an application. The goal is to have interoperability between devices and ecosystems. As the former project name suggests, it is based on the Internet Protocol (IP). The IP is the most common network layer used in homes and offices. This makes it ideal for delivering on interoperability and security to devices and services.

Matter provides a standard application layer that is used with a set of wireless technologies. The focus is on Bluetooth LE, Thread and Wi-Fi. This will be followed by other IP-supporting protocols such as Ethernet and cellular.

We enable your Matter projects

Our nRF Connect SDK has Matter support fully integrated and our solution is ready for prototyping. We will continue to implement the newest updates with every release.

We have sample programs for light bulbs, light switches, and door locks included in our nRF Connect SDK.
