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].
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.
