sf::Packet class of SFML-network be ported over to arduino for use with the Ethernet library or would it be too big? I'm working on a client-program where an arduino is a server and a regular computer is the client making a request. I'm using the SFML-network library to make networking easier on myself and would prefer to use the built in features of SFML to make networking easier. If it is not feasible would I be better off using fixed width data to communicate with the arduino
Without knowing how it all works, my guess is that you would have to port the whole of SFML, which would be HUGE. So, "No!" is the answer.
You could, of course, write a library of your own that had an SFML-like interface, but the Arduino networking libraries are already pretty simplistic and easy to use, so what's the point?
