I'm using the X-NUCLEO-IDW04A1. After a restart, the module no longer communicates via serial port (UART).
LED3 (Red - GPIO14) is On.
The 'MicroPython_mode' (pull_up GPIO8) at reboot work fine.
How can I restore the module?
You can restore the factory configuration by resetting the board with GPIO0 (J2 pin 4) pulled up.
Yes, thanks, but doesn't work. Still silent.
