[Plugin] OSC for UE4

As far as I can tell, your blueprints look good.

I think your issue is that your send address is , which mean “myself”.
So the Android is sending to itself, not the PC.

When a network communication does not work, try to break your problem into many sub problems with tools you know are reliable.
Example : use TouchOSC on Android to send messages, use an OSC monitor software on Windows to test the receiving part (there might be a firewall, a misconfiguration), etc.
