Using a custom GPS over NMEA


I’m trying to send NMEA data to a PixRacer via a NMEA connection. Is there a specific sentence that arudcopter requires? I’m not getting any 3D fix but have tested the GPS PicoScope and received the NMEA sentence:


Baud rate: 115200
Data rate: 5Hz

Mission planner settings have been correctly set up for GPS type of NMEA etc

Does Arducopter also need a RMC message or is GGA and VTG enough?
