RE: LAN module problem
According to Arduino site ,the new Ethernet lib can work with the W5500 chip so no need the Ethernet2 lib.
Link: https://www.arduino.cc/en/Reference/EthernetI tested also with the Ethernet2 lib from the ESP32 and it works.
Thanks.

RE: LAN module problem
I work with the Arduino IDE.
The Error is: cannot declare variable 'server' to be of abstract type 'EthernetServer'
I found a by-pass that solve the problem by changing the "cores/esp32/Server.h" file .
it works but it makes a new problem for other programs that use WiFi.
Is there a real solution ? -

The LAN W5500 demo program for Arduino is not working.
Any solution ?
