Hello, I flashed into WB55 FUS 2.1 and Wireless Stack V1.23. Then flashed BLE_p2pServer_reference.hex for an evaluation. But nothing happened. The device is not discovered. What is the problem? Something happened with the option Bytes after the upgrade?

Hi,

Did you flashed the hex file at the right memory section?

Try to enter into FUS and then start the BLE stack:

The STM32 Cube Programmer is Ver2.20.0. It selects the memory address automatically. However, after activating FUS and Wireless Stack, everything fell into place and started working. You've helped. Thanks a lot!
