Bluetooth Low Energy Expansion Board

Hardware Overview (3/5)

Key Product 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.

•M95640-RMC6TG 64-Kbit serial SPI bus EEPROM with high-speed clock interface

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.

X-NUCLEO-BNRG2A1

Important Hardware Additional Information

Hardware Overview (4/5)

BlueNRG-2 library does not work with the stock firmware that is loaded in the BLE

module of X-NUCLEO-BNRG2A1 expansion board.

For this reason:

•first of all, it is needed to solder on X-NUCLEO-BNRG2A1, if it is not soldered, a

0 Ohm resistor at R117.

•Then you can use a standard ST-Link V2-1 with 5 jumper wires female-female

together with STSW-BNRGFLASHER software tool (currently available only for

Windows PC) in order to update the firmware of the BLE module of X-NUCLEO-

BNRG2A1.

You need to connect the J12 pins of the X-NUCLEO-BNRG2A1 to the pins of the

ST-Link V2-1 as shown in the picture and follow the steps show in the next slide.

In particular we have the following connections:

J12 ST-Link V2-1

Pin 1 1

Pin 2 9

Pin 3 12

Pin 4 7

Pin 5 15

Important Hardware Additional Information

STM32 Nucleo with Expansion boards - Hardware Overview (5/5)

1. install the ST BlueNRG-1_2 Flasher Utility and open it,

then select the SWD tab

2. Erase the flash memory of the BlueNRG-2 chip

3. Download the Link Layer Only firmware for the BLE

module from the following link DTM_LLOnly.bin

4. Load the Link Layer Only firmware in the ST

BlueNRG-1_2 Flasher Utility and then press the

"Flash" button

5. If you need to restore the stock firmware of the BLE

module of X-NUCLEO-BNRG2A1, you can repeat the

procedure using this firmware image DTM_Full.bin

6. If you should find some issues during the update

process, you can try to repeat the procedure closing

the J15 jumper on the X-NUCLEO-BNRG2A1

expansion board.

FP-SNS-MOTENV1

Software Overview

Software Description

•FP-SNS-MOTENV1 is an STM32Cube function pack, which lets you connect your IoT node to a

smartphone via BLE and uses a suitable Android™ or iOS™ application, such as the ST BLE

Sensor app, to view real-time motion and environmental (such as temperature, relative humidity,

pressure) and sensor data.

•This package also enables advanced functions such as the sensor data fusion and accelerometer-

based real-time activity recognition, carry position, gesture recognition, motion intensity recognition

and real-time information about the number of steps and cadence which the user just performed

with the device, i.e. cell phone.

•Together with the suggested combination of STM32 and ST devices, it can be used to develop

specific wearable and environmental monitoring applications, or smart things applications in

general.

Key features

•Complete firmware to develop an IoT node with BLE connectivity, environmental and motion

sensors.

•Middleware libraries for sensor data fusion and acelerometer-based real-time activity recognition,

carry position, gesture recognition, motion intensity recognition and pedometer

•Compatible with ST BLE Sensor applications for Android/iOS, to perform sensor data reading,

motion algorithm features demo and firmware update (FOTA)

•Easy portability across different MCU families, thanks to the STM32Cube

•Free, user-friendly license terms Latest info available at www.st.com
