Hello! I was running the debug in Keil to my STM32WB55 board, and suddenly the notebook turned off due to low charge. When I turned on the notebook and connected the board , the advertising led didn't blink anymore, that is, the board stopped advertising. I searched in the forum, found some answers and tried to reflash my coprocessor. It seemed to work but after a short time it went back to the same situation. When I turn on , It sometimes advertises but sometimes not. How can I solve it? One more info: when I was flashing using CMD interface(USB) I deleted the wireless stack and when I downloaded the new FUS it gave the error "firmware not authentic", but after this I checked the version of FUS on the board and I saw that it has uploaded even with that error.
