Port Configuration - northern-bites/nbites GitHub Wiki

At a venue, specific ports may be blocked/opened. If the standard UDP/TCP ports 4000-4010 are not working, you will need to change the robot's UDP ports to use different ones. Ask the venue organizer for what ports they want you to use, then set the global constants UDP_PORT, TCP_PORT, TOOL_PORT and STREAMING_PORT_BASE in CommDef.h to these new port numbers. Note that STREAMING_PORT_BASE makes the ~8 ports following it unusable, so set this port to the highest port number.

Remember to change them back when you get home.
