I tried the echoserver example from this https://os.mbed.com/users/mbed_official/code/TCPEchoServer/
and everything worked fine for me. I need now to upgrade the lwip library to lwip 2.0.3. when I did that I faced a lot of issue. I know that I have to make a lot of changes after upgrading the library but I’m not expert with the tcp communication. Could you please provide any simole example using the lwip 2.0.3?
