Matter, which began as Project CHIP (Connected Home over IP) started in December 2019. The starting companies were 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 easy for manufacturers to create secure and reliable solutions. These solutions will be interoperable with the major smart home ecosystems like Apple’s Siri, Google’s Assistant, and Amazon’s Alexa.
Matter is using Thread, Wi-Fi, and Ethernet for transport and Bluetooth LE for commissioning. All Matter devices based on Thread are required to feature Bluetooth LE concurrently to enable adding new devices to a network. Wi-Fi can be used for low and high bandwidth applications. It can be used for devices in range of the local Wi-Fi. Thread is an IPv6-based mesh protocol that targets low bandwidth applications. It is the go-to option for battery-powered devices that require the best energy efficiency and for simple actuators like smart plugs or light bulbs. Most mains-connected Thread devices work as a Thread router and will expand the network's range. Thread is a self-healing low-power mesh that can adapt to new devices or to devices being removed from the network.
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.
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 ,Wi-Fi and Ethernet. This will be followed by other IP-supporting protocols such as cellular.
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. To learn more, have a look at our user guide about Matter
These examples show the usage of Matter with our nRF connect SDK. The weather station example lets you remotely gather different kinds of data. It collects temperature, air pressure, and relative humidity, using the device sensors. The resulting device works as a Matter accessory device. It can pair and be remotely controlled over a Matter network built on top of a low-power, 802.15.4 Thread network. Use these samples as references to create your own devices
