STM32CubeWB Bluetooth® LE MCU Package


Click here for Bluetooth® Low Energy Overview

1. Introduction

The STM32CubeWB MCU Package[1] provides software components running on STM32WB Series MCUs.
For all examples provided with the package, the following integrated development environments are supported:

  • STMicroelectronics integrated development environment for STM32 products (STM32CubeIDE)
  • IAR Systems® IAR Embedded Workbench® for Arm® (EWARM)
  • Keil® Microcontroller Development Kit (MDK-ARM)

The Firmware Package for the STM32WB series is also available on STM32CubeWB github[2].

2. STM32WB Bluetooth® LE software architecture

The STM32WB Bluetooth® low energy architecture separates the Bluetooth® Low Energy Profile and application, running on the application Cortex®-M4, from the Bluetooth® low energy real-time aspects residing in the Bluetooth® Low Energy Peripheral.

The Bluetooth® Low Energy peripheral incorporates a Cortex®-M0+ processor containing the Bluetooth® Low Energy STACK handling the link layer up to the generic attribute profile and generic access profile layers.
