BLE functionality discrepancy on custom board with STM32WB55CE MCU

Hello ST Support Team,

I am currently facing an issue with the BLE functionality on my custom board utilizing the STM32WB55CE MCU. While the code works flawlessly on the STM32WB Nucleo EVK, the BLE feature doesn't seem to function as expected on my custom board.

Upon further investigation, I observed a disparity in the wireless firmware version and build values between the two boards. When running the code on the EVK, I received wireless firmware version 1.13.2 with a build value of 2. However, on my custom board, both values indicate 0. Meanwhile, both boards display the same FUS version value, which is 1.2.0.

I have also tried to re-flashing of BLE firmware but receive the error in flashing.
I used following link for reference and follow all steps. Also used "stm32wb5x_BLE_Stack_full_extended_fw.bin" file and address "0x08051000".

I tried to flash the BLE stack firmware multiple times but not worked in my case. It every time throw error message of erase/write operation failed.

It would be really helpful to me if any guidance or assistance you can provide to help me troubleshoot and rectify this issue with the BLE functionality on my custom board. Could you please advise on the necessary steps to verify and potentially resolve this discrepancy
I look forward to your valuable guidance to address this concern.

Thanks,
Sjain

Hello,

Can you try with the latest version of STM32CubeProgrammer tool (v2.15.0) and follow these steps? 

- Connect

- Start FUS

- Read FUS to check the version 

- If a stack version is displayed, perform the firmware upgrade without first install option checked 

Best Regards

Hello,

According to your second screenshot, you tried to flash the wireless stack at 0x0805A000 instead of 0x08051000 as mentioned in the release note. Can you retry with the right address?

Hi @Remy ISSALYS ,

I tried to flash the wireless stack at 0x08051000 as mentioned in the release note. Still receive the same error in flashing. Please suggest the steps to make BLE working on my board.

@Remy ISSALYS Thank you for the steps.
Now BLE working on my custom board after flashing the firmware.

Now only one issue I face that sometimes BLE advertisement not started.
when I debug the issue at that time I found that sometimes instead of WIRELESS_FW_RUNNING event I received FUS_FW_RUNNING event.
Can you please suggest method to receive the WIRELESS_FW_RUNNING state every time ?
Can we configured this states from application?
