Issues with M9N GPS and Ardupilot
-
Hi,
I am currently using a voxl 2 (SDK 1.4.0) running ardupilot version 4.7.0-4803bc14. I have attached a Holybro M9N GPS micro via the J19 connector. When using px4, I am seeing the GPS reading on the map for QGC, and the commandvoxl-inspect-gpsgives out the expected readings. We are trying to use ardupilot, and for some reason when disabling px4 and enabling ardupilot, I lose the ability to see the GPS in QGC and runningvoxl-inspect-gpsshows nothing - however the voxl still connects to QGC. In the documentation, most of the GPS information is linked to when using px4, can GPS be used with ardupilot? If so, how? -
@cguzikowski Yes, we have tested Ardupilot with GPS and have customers using Ardupilot with GPS. However, I don't know that anyone has ever tried with an M9N unit so perhaps there is some issue with that. Can you try with one of these: https://store.3dr.com/mini-gps-ublox-max-m10s/?

@Eric-Katzfey Thank you for the response, we don't have that GPS and would like to try to get the M9N to work if possible. Is there any troubleshooting we can try before purchasing a new unit? PX4 has a .conf file in
/etc/modalai, I don't see one for Ardupilot, could this be an issue? I have also tried to tweak the parameters in the file/data/APM/defaults.parmand also through QGC, but have had no luck. -
@cguzikowski No, there is no Ardupilot configuration file needed in
/etc/modalai
