Hello
I've tried to use this with an ESP32 (I modified some defines for the architecture, to make it compatible). In MyHwESP32.h I've changed
#define MY_SERIALDEVICE Serial
to
#ifndef MY_SERIALDEVICE
#define MY_SERIALDEVICE Serial
#endif
I think this why it doesn't work for you @ricorico94 with version 2.3 of MySensors.
It worked sometimes, but usually Putty responds "Network error: Connection refused"
Any ideas?
