Master wireless embedded development with Zephyr on STM32WBx MCUs
STMicroelectronics & Avnet/Silica invites you to these 2 upcoming online workshops led by EMEA experts featuring wireless development based on Zephyr.
Matter
Supported by the STM32WB MCU, Matter is an application layer, which aims at making smart home devices interoperable.
An open-source standard, Matter ensures seamless interactions between connected devices across different IP technologies. It is available in the Matter GitHub.
In a Matter network, Bluetooth® LE is used to commission devices. It runs in a dynamic concurrent mode with the Thread protocol.
Multiple protocols running on the same MCU
The STM32WB multiprotocol MCUs can run Bluetooth® LE together with 802.15.4 wireless protocols, Zigbee, or OpenThread protocols in concurrent modes.
This enables more convenient device management during installation and configuration, and significantly improves overall user experience.
