P-NUCLEO-WB55 RF problem

[YSN]

I have P-NUCLEO-WB55 it worked initially well with BLE stack. Later I have ported Zigbee Stack but things were not working out. I went back and loaded the BLE stack now, but it is not even advertising with p2p sever application. I have tested the GPIO and UART functions works well. But only the RF is not seems getting activated.

1. I have tried erasing chip and loading the stack and app freshly from pre-built images (not working)
2. I have reinstalled the FUS through cubemx programmer but did not helped.
3. I tried loading transparent mode application, but it is not connecting to virtual COM port detected in STMCube RF monitor tool as well ?

The USB dongle came with kit works fine but the Nucleo board is not working. Is there any way to restore the board to factory default ?

If RF is not working means, some thing wrong with Hardware ?

Could you download all the option bytes?

are you able to read the FUS version with CubeProgrammer?

what is the version of Cubeprogrammer tool you are using?
