SPWF04SA no longer communicates

Posted on July 03, 2017 at 17:35

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.
