EthernetServer ethServer(502) will not compile

[jbr007]

Hi,

I am using ESP32-S3 and have some issue trying to setup the server.

#include <Arduino.h>
#include <SPI.h>
#include <Ethernet.h>

#include <ArduinoRS485.h> // ArduinoModbus depends on the ArduinoRS485 library
#include <ArduinoModbus.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

EthernetServer ethServer(502);

will give error message:

cannot declare variable 'ethServer' to be of abstract type 'EthernetServer'"

Any solution?

It works on ethernet2.h

you use old version of the esp32 platform. espressif/arduino-esp32#10274
#241

Closing as duplicate of #88, which has been resolved by espressif/arduino-esp32#9447

@jbr007 you can fix the problem by updating to version 3.0.0 or newer of the "esp32" boards platform. Instructions here:
