This video is part of TechXchange: Why Matter Matters
Designed for smart homes and smart buildings, the Matter IoT ensures seamless interactions between connected devices across different IP platforms. Matter is an application layer that addresses many applications in an open-source delivery and certification infrastructure.
Connected devices using Matter run based on Wi-Fi or Thread technologies, and each device has a specific role within the Matter network. These devices support a connectivity technology within Wi-Fi, Ethernet, or Thread as network communication protocol. Such devices also need to support Bluetooth LE (BLE) technology.
STMicroelectronics' STM32WB can run BLE and Thread in concurrent modes, which is necessary for device commissioning, with 1 MB of flash and 256 kB of RAM to support application layer and connectivity stacks. The Quad-SPI peripheral extends the memory size externally with execution in place, and can implement over-the-air firmware updates.
The STM32WB MCU comes with the NUCLEO-WB55RG and the discovery board STM32WB5MM-DK, which brings a wide feature set, including sensors, external flash, screen, and touch sensors for applications running on Matter.
