Stratux external gps

[scubasteve4140]

Just put stratux on my Raspberry pi 4 that has a waveshare sim7600gh m.2 hat. Everything works fine when using a ublox usb for my gps receiver, however, I want to be able to use an external gps source. I am getting NMEA messages from my external gps antenna but Stratux isn’t recognizing/packaging it correctly for Foreflight to use it as a gps source. Is there something I can modify in ssh on Stratux for it to recognize external gps as its primary source? My gps information is coming across ttyUSB1.

Your NMEA stream needs to show up as /dev/serialin. A quick hack could be a symlink in rc.local or a more sophisticated way would be to create a new udev rule.

I ended up putting this at the end of the interface template before I seen your message.

NMEA Input Configuration

nmea:

• type: udp
  port: 49002
  address: 192.168.1.10

I will give this a shot in the morning and see what it does. If it doesn't work I'll make a change with your recommendations, thanks for the reply!

I created the symlink and it recognizes my external gps source but I can't get the file to stay saved after it reboots. Foreflight is still showing gps connected in devices but no data is getting through.

you need to enable persistent logging temporarily followed by a reboot to apply your changes:

then you may switch back
