BlueNRG-2 library does not work with the stock firmware that is loaded in the BLE module of the X-NUCLEO-BNRG2A1 expansion board.
Nechikonzero ichi:

• 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 the TSW-BNRGFLASHER software tool (currently available only for Windows PC) to update the firmware of the BLE module of X-NUCLEO-BNRG2A1.

In particular, we have the following connections:

	J12	ST-Link V2-1
Pin	1	1

1. Install the ST BlueNRG-1_2 Flasher Utility and open it, then select the SWD tab.b
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. binn
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.bi.n
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 application, there is inside the package one folder called “Binary”

Rine:

• YeNUCLEO-F401RE uye NUCLEO-L476RG:
  • pre-compiled FP-SNS-FLIGHT1 FW that could be flashed to a supported STM32 Nucleo for X-NUCLEO-53L3A2 using the STM32CubeProgrammer 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 for X-NUCLEO-53L3A2 using the STM32CubeProgrammer or by doing “Drag & Drop”
  • Important Note: This pre-compiled binary is not compatible with the FOTA update procedure
  • pre-compiled FP-SNS-FLIGHT1 FW that could be directly flashed to a supported STM32 Nucleo for VL53L3CX-SATEL using the STM32CubeProgrammer or by doing “Drag & Drop”
• YeNUCLEO-U575ZI-Q:
  • pre-compiled FP-SNS-FLIGHT1 could be directly flashed to a supported STM32 Nucleo (for X-NUCLEO-53L3A2 and for VL53L3CX-SATEL) using the STM32CubeProgrammer or by doing “Drag & Drop”.
  • Important Note: For the first installation, after the full flash erase (suggested procedure), use the STM32CubeProgrammer to set the STM32 MCU user byte settings to use bank 1 for flashing the firmware and start the application

How to install the code after compiling the project for NUCLEO-F401RE and NUCLEO-L476RG:

• Compile the project with your preferred IDE

In the folder Utilities, there is a script *.sh that performs the following operations:

• 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:Thiss additional pre-compiled binary is not compatible with the FOTA update procedure

Before executing the *.sh script, it is necessary to edit it to set the installation path for STM32CubeProgrammer.
BootLoaderPath and BinaryPath as input are required when executing the .sh script.
