Hi @gilmaimon your library is great but somehow it is now broken with Arduino_esp32 version 3.0.0, it would be great if you could accept this PR and make a new release. This way we can continue to use your nice library directly and don't have to fork. thanks you for your work @mazgch

Hi @mazgch!

Thank you for tagging me and taking the time to open this PR

I really haven't done anything related to this Repo (or Arduino in general) in the past years.

I'll take the time to merge and release a new version with your changes. Thank you!

Thanks @gilmaimon it is working for me and compiling now in Arduino_esp32 v3.0.0, I still get one warning regarding the use of a deprecated function in esp32_tcp.hpp:50 which can be solved and worked around like this:

    TcpClient* accept() override {
      while(available()) {
#if (ESP_ARDUINO_VERSION >= ESP_ARDUINO_VERSION_VAL(3, 0, 0))
        auto client = server.accept();
#else
        auto client = server.available();
#endif
        if(client) {
          return new Esp32TcpClient{client};
        }
      }
      return new Esp32TcpClient;
    }

it is due to :

esp32/3.0.0/libraries/Network/src/NetworkServer.h:50:17: note: declared here
   50 |   NetworkClient available() __attribute__((deprecated("Renamed to accept().")));
