GPS Troubleshooting

[Stefan Amundarain]

We recently connected a Matek M10Q GNSS/Compass to the J19 port of our voxl2. we have a green light on the GPS, and when in the window a blinking Green to indicate GPS fix. We are able to calibrate the compass in PX4, but no GPS data is being recieved. We have the GPS wired correctly. based in the docs.modalai voxl2 onboard sensor user guide. what other steps can we take to troubleshoot? I have also checked voxl-px4.conf and GPS= AUTODETECT

@Stefan-Amundarain First GPS lock takes a lot longer than subsequent locks. I'd recommend taking the GPS outside for 15 minutes or so for initial lock.

@tom just spent about 20 minutes outside with it, no luck. We will try a different GNSS module and see if its the equipment or the setup.

@Stefan-Amundarain What version of VOXL SDK are you running? Can you provide the output of voxl-version?

[rdjarvis]

@Eric-Katzfey we were on 1.3.2, flashed 1.3.5 and had success!

[Eric Katzfey]

@rdjarvis Okay, great! Instead of starting voxl-px4 with systemctl start voxl-px4 can you start it as a foreground process using voxl-px4 -d and then capture the output and paste as a response? I'd like to see if there are any error messages printed that could help determine why it isn't seeing your GPS unit.
