Matter is an open-source standard, ensuring interoperability and hosted by the Connectivity Standards Alliance (CSA).

Matter ensures seamless interaction between connected smart homes and smart building devices across different IP technologies. The standard ensures that multiple brands can interact smoothly and securely ensuring data privacy.

The Matter application layer allows wide adoption by addressing many applications in an open-source delivery and certification infrastructure.

“Smart home devices should be secure, reliable, and seamless to use.

And with Matter, they are.”

The roles of connected devices in a Matter network

In smart homes, connected devices run based on Wi-Fi, Thread or Ethernet technologies, and each device has a specific role within the Matter network.
Such devices also need to support commissioning, the process of adding a new device to an existing Matter network. Device commissioning can be done via Bluetooth^® Low Energy with the help of near field communication (NFC).

End devices are connected objects serving a final application like lights or door locks.
Router/Bridges objects such as gateways route data from an end device, transferring it from one protocol to another (Wi-Fi to Thread for example).
Controllers are devices such as smartphones or tablets used to add an end device to a Matter network. Device commissioning is done over Bluetooth^® Low Energy. This can be initiated by entering a passcode manually, scanning a QR code, or using NFC with a simple tap from a smartphone.

Matter bridge use-case

Why use NFC for device commissioning?

As a widespread technology already integrated into most smartphones, NFC is an intuitive and reliable solution for onboarding, which streamlines the commissioning experience. Since NFC can be completely integrated into devices, it is both robust and discreet.

In addition to device commissioning, NFC can be used to change device parameter settings, enable customer re-engagement tactics, and more.

Why use a Secure Element to attest that devices belong to the Matter ecosystem?

Ensure that a Matter device is genuine and interoperable with a Secure Element that provides manufacturers’ certificates and manages Matter device attestation. STSAFE secure microcontrollers are personalized with the device manufacturer’s credentials and pre-configured with the cryptographic protocol for Matter device attestation. Device manufacturers that use STSAFE can prevent Matter object cloning and Matter object overproduction without having to implement cost-prohibitive or complex security processes during object configuration.

Matter software samples for STM32

ST provides example projects showing the usage of Matter with our STM32 MCUs for two use cases.

One demonstrates a Matter device over Thread and a gateway in RCP mode implemented on our STM32WB series of 2.4GHz wireless microcontrollers, while the other showcases how to create a Matter to no-Matter technology bridge based on our STM32H7 high performance series.
