# X-CUBE-BLE2 Firmware Package

![latest tag](https://img.shields.io/github/v/tag/STMicroelectronics/x-cube-ble2.svg?color=brightgreen)

The X-CUBE-BLE2 is an expansion software package for STM32Cube. This software provides drivers running on STM32 for STM's BlueNRG-2 Bluetooth Low Energy device. This software package is built on top of STM32Cube software technology that ease portability across different STM32 microcontrollers.

**X-CUBE-BLE2 software features**:

- Complete middleware to build applications using BlueNRG-2 network processor.
- Easy portability across different MCU families thanks to STM32Cube.
- Sample applications that the developer can use to start experimenting with the code.
- References to free Android and iOS Apps that can be used along with the sample applications.
- Free, user-friendly license terms.
- Examples implementation available for X-NUCLEO-BNRG2A1 STM32 expansion board plugged on top of one NUCLEO-L476RG.

The figure below shows the overall architecture.

- At the bottom layer there are the HW components: the STM32 MCU and the BlueNRG-2 network processor.  
- The drivers abstract low level details of the hardware and allow the middleware software to provide Bluetooth LE features in a hardware independent fashion.
- The applications provide examples of how to use the code.
