STM32 Wireless supports Bluetooth 5.3 standard as well as the 802.15.4 wireless protocols to fulfil the requirements of a wide range of applications looking for best‑in‑class radio performances.

The STM32WB series is a dualcore, multi-protocol and ultra-low-power 2.4 GHz MCU system-on-chip. Based on ST’s best-in-class,ultra-low-power STM32L4 MCU, the STM32WB series reduces development time and BOM cost, extends application battery life and inspires innovation thanks to its rich and flexible peripheral set.

The STM32WB55 Nucleo pack, STM32WB Nucleo boards and STM32WB Discovery board combined with the STM32Cube Ecosystem form a consistent set of hardware and software development tools to quickly and easily start developing your application.

Additional dedicated development tool for connectivity (STM32CubeMonRF) is also available for radio tuning, to speed up the time-to-market.
