- Install the ST BlueNRG-1_2 Flasher Utility and open it, then select the SWD tab.b
- Erase the flash memory of the BlueNRG-2 chip.
- Download the Link Layer Only firmware for the BLE module from the following link: DTM_LLOnly. binn
- Load the Link Layer Only firmware in the ST BlueNRG-1_2 Flasher Utility and then press the “Flash” button.
- 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
- 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.

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.
