Generally, the problem is solved. All you need to do is initialize the PHY for ESP32 using the ETH.h library from the Espresiff package. Then it's a matter of eliminating the Wi-Fi initialization that is automatically started for ESP32. Interestingly, you can use two IP addresses at the same time, one from the PHY and the other from Wi-Fi - of course, Mysensors responds to both. If anyone is interested in the solution - I invite you to talk. I started Mysensors on the PHY of the Kicony KC868-A16 board and it works great.

Hi.
If i Try compile sketch with mysensors 2.3.0 - everything is ok. But after upgrade to 2.3.1 or 2.3.2 i have this error. Where is the problem ?
