P-NUCLEO-WB55 BLE stack and FUS programming problems

Andrea_Mutti · ‎2025-09-24

Hi all,

i'm working on a project involving BLE and I wanted to use the P-NUCLEO-WB55 board as a BLE sniffer as described here: https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32_Sniffer_for_BLE_Setup_guide#Hardware

I managed to find a P-NUCLEO-WB55 board used by a colleague for old projects and I was trying to follow the guide at previous link to set-up the board but I cannot download the BLE stack, nor update the FUS.

I am using STM32CubeProgrammer 2.20.0, and by reading FUS infos I get the following reply:

The option bytes are set as listed in the attached file.

I tried also to follow the procedure shown in this video (How to program a STM32WB55 with STM32CubeProgrammer ) having the following result:

Is it possible to restore the stack on this board?

Kind regards,

Andrea

Hello @Andrea_Mutti and welcome to the ST Community

Could you please try to:

Open the STM32CubeProgrammer V2.20.0.
Go to the FUS tab, select the path of the stm32wb5x_FUS_fw_for_fus_0_5_3.bin from the STM32CubeWB V1.23.0(make sure to use the last STM32CubeWB version), make sure to select the Start address automatic determination option and click on the Firmware Upgrade button.
If this works fine, do the same as step 2 with the stm32wb5x_FUS_fw.bin.
After that, go and upload the Stack you want (same process as .bin files of the FUSs).
Read FUS infos to check if it is well installed and use the Start wireless Stack to be able to use your board without issues on a Wireless application.

Best Regards.
