ST X-NUCLEO-BNRG2A1 Getting Started

Getting started with the X-NUCLEO-BNRG2A1 BLE expansion board based on
Introduction
The X-NUCLEO-BNRG2A1 expansion board provides Bluetooth low energy connectivity for developer applications and can be
plugged onto an STM32 Nucleo
through its Arduino UNO R3 connectors.
The expansion board features the Bluetooth
based on the ST BlueNRG-2
Cortex-M0 core and programmable Flash, which can accommodate custom applications developed using the SDK. The
BlueNRG-M2SP module supports master and slave modes, increased transfer rates with data length extension (DLE), and
AES-128 security encryption.
The X-NUCLEO-BNRG2A1 interfaces with the
which can be configured by the hardware.
