Bluetooth Low Energy expansion board
Hardware Overview
X-NUCLEO-BNRG2A1 Hardware Description
•The X-NUCLEO-BNRG2A1 is a Bluetooth Low Energy (BLE) evaluation and
development board system, designed around ST’s BLUENRG-M2SP Bluetooth
Low Energy module based on BlueNRG-2.
•The BlueNRG-2 processor hosted in the BLUENRG-M2SP module communicates
with the STM32 microcontroller, hosted on the Nucleo development board,
through an SPI link available on the Arduino UNO R3 connector.
Key Products on board
BLUENRG-M2SP
Bluetooth Low Energy, FCC and IC certified (FCC ID: S9NBNRGM2SP, IC:
B976C-BNRGM2SP), module based on Bluetooth® Low Energy wireless network
processor BlueNRG-2, BLE v5.0 compliant.
BLUENRG-M2SP integrates a BALF-NRG-02D3 balun and a PCB antenna. It
embeds 32 MHz crystal oscillator for the BlueNRG-2.

X-CUBE-BLE2
Software Overview
5
X-CUBE-BLE2 Software Description
•The X-CUBE-BLE2 is a software package which provides STM32 drivers running
for the BlueNRG-2 Bluetooth Low Energy device. It is an STM32Cube expansion
software package that eases portability across different STM32 MCU families
•Implementation examples are available for the STM32 Nucleo Bluetooth Low
Energy expansion board (X-NUCLEO-BNRG2A1) plugged on top of an STM32
Nucleo board (NUCLEO-L476RG)
Key features
•Complete middleware to build applications using the BlueNRG-2 network
processor
•Easy portability across different MCU families thanks to the STM32Cube
•Sample applications that the developer can use to start experimenting with the
code
•References to free Android and iOS app that can be used along with the sample
applications
•Free, user-friendly license terms

Setup & Application Examples
HW limitation
•Warning Even if not strictly required for the correct working of the BlueNRG-2 module, to correctly
set the BlueNRG-2 RESET pin on pin D7 of theArduino connector a 0 Ohm resistor must be
soldiered on R117. Alternatively, the D7 pin and the pin #5 of the J12 on the X-NUCLEO-
BNRG2A1 expansion board must be bridged (as shown in the picture).
