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

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.

1. How to install the pre-compiled binary:
•For each applications, there is inside the package one folder called “Binary”
•It contains:
•pre-compiled FP-SNS-FLIGHT1 FW that could be flashed to a supported STM32 Nucleo Board using the ST-Link at the right
position (0x08004000)
•Important Note: this pre-compiled binary is compatible with the FOTA update procedure
•pre-compiled FP-SNS-FLIGHT1 + BootLoader FW that could be directly flashed to a supported STM32 Nucleo Board using the
ST-Link or by doing “Drag &Drop” (the latter only for STM32 Nucleo boards)
•Important Note: this pre-compiled binary is not compatible with the FOTA update procedure

Setup Overview

2. How Install the code after compiling the project:
•Compile the project with your preferred IDE
•On Windows: for each IDE and for each platform there is one batch script:
•IAR toolchain Embedded Workbench V9.20.1:
•CleanFLIGHT1_IAR_53L3A2_F401.bat
•CleanFLIGHT1_IAR_ 53L3A2_ L476.bat
•Keil µVision 5 toolchain - MDK-ARM Professional Version: 5.37.0:
•CleanFLIGHT1_MDK_ARM_ 53L3A2_ F401.bat
•CleanFLIGHT1_MDK_ARM_ 53L3A2_ L476.bat
•Integrated Development Environment for STM32 - STM32CubeIDE Version 1.110:
•CleanFLIGHT1_STM32CubeIDE_ 53L3A2_ F401.bat
•CleanFLIGHT1_STM32CubeIDE_ 53L3A2_ L476.bat
•For Linux/iOS: only for STM32CubeIDE and for each platform there is one for STM32CubeProgrammer:
•CleanFLIGHT1_STM32CubeIDE_ 53L3A2_ F401.sh
•CleanFLIGHT1_STM32CubeIDE_ 53L3A2_ L476.sh
•It’s necessary to edit this file for setting the right installation of the STM32CubeProgrammer
•These scripts perform the following steps:
•Full Flash Erase
•Flash the right BootLoader at the right position (0x08000000)
•Flash the FLIGHT1 firmware at the right position (0x08004000)
➢This is the firmware that was compiled with the IDE
➢This firmware is compatible with the FOTA update procedure
•Save a complete Binary FW that includes both FLIGHT1 and the BootLoader
➢This binary can be directly flashed to a supported STM32 board using the ST-Link or by doing “Drag & Drop”
➢Important Note: this additional pre-compiled binary is not compatible with the FOTA update procedure
