I put an ethernet shield on an arduino uno. also no connection with my node.js socket.io server, I used also your app.js and the older socket implementation.
is there a way to debug the conncetion on the arduino?
I can send udp, read http with the ethernet shield. any ideas? would be realy great to get help.
regards
