In the moment I rewrite my Arduino eOS library, which allows using TCP.When I send data it works, in the Diagnostics tab I see the data arrives.In Wireshark I see only feedback of the UDP port, but the diagnostics says there is also outputting TCP:Is the TCP feedback switched off? Or did I something wrong. Also what ist the meaning of "OSC TCP Server Ports"?
Ok, I have to investigate with the Arduino Ethernet. TCP reply works with TouchOSC 1.06b
