Sample implementations are available for:
1. STM32 Nucleo with expansion boards
•NUCLEO-F401RE (or NUCLEO-L476RG) + X-NUCLEO-BNRG2A1 + X-NUCLEO-53L3A2

Bluetooth Low Energy Expansion Board
Hardware Overview (1/4)
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.

VL53L3CX Nucleo expansion board (X-NUCLEO-53L3A2)
Hardware Overview (2/4)
Key Product on board
•VL53L3CX Time-of-Flight (ToF) ranging sensor with multi target detection
•0.25, 0.5 and 1mm spacers to simulate air gaps, with the cover glass
•Cover window (made by Hornix) sample with low cross-talk ready to use / clipable on
VL53L3CX
•Two VL53L3CX breakout boards
X-NUCLEO-53L1A2 Hardware Description
•The X-NUCLEO-53L3A2 is a ranging sensor with multi target detection
evaluation and development board designed around the VL53L3CX
sensor based on ST FlightSense™Time-of-Flight technology.
•The VL53L3CX communicates with the STM32 Nucleo developer board
host microcontroller through an I2C link available on the Arduino UNO R3
connector.

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

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.
