Raspberry pi setup?

It sure looks like the Vesper is in /dev/ttyUSB0. Is there any way you can verify that it is pushing out NMEA data? Does it have it;s own WiFi connection that you can connect to.

So far you have kplex running but not spitting out any data, Vesper attached, perhaps not putting out any data for kplex to retransmit (?).
