Hey Remi, I just want to reset the device, I've the STM32WB55 Nucleo Pack.

Because now when I'm using the cubeProgrammer in the "erasing and Programming" and I browse and after I start programming, the device is not working as before.

I coded just a blink light LED 1 and LED 3 on STDCubeIDE, and I built it. Before was working completely perfect! I tried to reset because I needed to start a new project with the device, I tryied to pair USB_STLINK and the USB Dongle. And now I can't pair neither make it blink as it was doing before.

Sorry, I'm just a beginner and a student.

Few questions:

Just to confirm, are you working on the Nucleo board or on the dongle?

If with Nucleo board (I suppose), do you want to communicate with the BLE dongle?

Can you download the option bytes to check whether something is wrong?

Does the issue happen with the same project just after reset or with a new project?
