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 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 the Arduino connector a 0 Ohm resistor must be
soldiered on R117. Alternatively, the D7 pin and the pin #5 of the J12 on the X-NUCLEOBNRG2A1 expansion board must be bridged (as shown in the picture).

STM32 Open Development Environment
Fast, affordable Prototyping and Development
21
• The STM32 Open Development Environment (STM32 ODE) is an open, flexible, easy, and affordable way
to develop innovative devices and applications based on the STM32 32-bit microcontroller family combined
with other state-of-the-art ST components connected via expansion boards. It enables fast prototyping with
leading-edge components that can quickly be transformed into final designs
