Please, witch protocol uses stm32w device if nBOOT is selected (and serial-link-bootloader is selected) ? Is it USART protocol used in the STM32™ bootloader (AN3155) ? Because, my stm32w device in bootloader mode responds to any character, also 0x7F - start sequence with NACK (0x1F).

Thank you for answer.
