I am trying to use an external GPS (either connected directly to the Pixhawk, or via USB) to get surface position data (note, this is for a topside project, nothing underwater). I cant seem to get either method to work anymore (they used to), I’m using most recent ArduSub/companion and QGC. They appear to show position on the map, however there is no data reported to the gauges (lat/long etc) which is needed for video overlay. If I use the NMEA Router method, the same USB GPS works fine (so there is nothing wrong with the GPS).
Is this expected, or is there something wrong here?
I have tried numerous GPS units, baud rates, different com ports, GPS data rates, QGC GPS config settings, etc but can’t seem to solve the issue.
Thanks a lot
