1. Introduction

The STM32CubeWB MCU Package^[1] provides software components running on the STM32WB Series MCU.
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].

It contains the following Bluetooth® LE applications delivered as source code.

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.
