Hello, I many years used ST-Link to download my framework to STM32, so I am not new in this.
But now - I used all available settings in - ST-LINK software (under reset, hot, normal, with different frequency). I pushed reset in the boards, I connected boom0 to 3.3V to GRN. I used many jumpers in the Nucleo board.
How it is happened!
Initially this boards worked. I created simple code - for turn on LED.
After that I decided to test the wireless connection and uploaded the .hex file from here - P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_HeartRate\Binary
it was not successful attempt, BUT after that I could not establish connection with boards, please the images.
How I can fix it?
