Description

I'm using a w5500 with the esp32 and I need to get both wifi and ethernet working, as a client and as a TCP server. I have not found any examples. If I try to use the Arduino's "Ethernet.h" library, it works as a TCP client but not as a TCP server. When compiling I get the error "virtual void Server::begin(uint16_t)" How can I do? thank you all

Sketch

#include <WiFi.h>
EthernetServer serverTcpEth(portServerTCP);

Debug Message

error: cannot declare variable 'serverTcpEth' to be of abstract type 'EthernetServer'
note:   because the following virtual functions are pure within 'EthernetServer':
 class EthernetServer : public Server {
       ^~~~~~~~~~~~~~
note: 	'virtual void Server::begin(uint16_t)'
     virtual void begin(uint16_t port=0) =0;
                  ^~~~~

Hi Felix,
Thanks for the reply. I've read, but I haven't found any solutions.
In my specific case, I need an ethernet TCP server and it doesn't compile either.

Hello @Impavido85

it looks like it is in the works. See this PR.

Thanks

Yes, this is something which will be investigated.

@Impavido85 I saw somewhere else to change the server.h line from

virtual void begin(uint16_t port=0) =0;

to

void begin() {};

You can give it a try and see if it works.

Yes, this is something which will be investigated.

This is an external library that will be made obsolete with 3.0.0 and the ETH updates we have ready there

Are there news? Thanks
