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.

Software Description
•The FP-SNS-FLIGHT1 is an STM32Cube function pack which let your IoT node
connect to a smartphone via BLE and uses a suitable Android™or iOS™application
like the STBLESensor app to view real-time environmental time-of-flight sensor data.
•This package, together with the suggested combination of the STM32 and ST
devices, can be used to develop wearable applications, or smart things applications
in general.
Key features
•Complete firmware to develop an IoT node with BLE connectivity and time-of-flight
sensors
•Sample implementation available X-NUCLEO-53L3A2 and X-NUCLEO-BNRG2A1
connected to a NUCLEO-F401RE or NUCLEO-L476RG
•Compatible with STBLESensor application for Android/iOS, to perform sensors data
reading, audio and motion algorithms features demo, and firmware update (FOTA).
•Easy portability across different MCU families, thanks to STM32Cube.
•Free, user-friendly
