Preflight Fail: Compass Sensor 0 missing
-
@Nitin-Varma-Vegesna In
/etc/modalai/voxl-px4.confset GPS to NONE. Then set the PX4 parameters SYS_HAS_GPS, and SYS_HAS_MAG to 0. Set EKF2_MAG_TYPE to 5. Set EKF2_GPS_CTRL to 0. Then reboot and see if the preflight error is cleared.@Eric-Katzfey Ok, also is there a way to buy the GPS chip since I did not see it on the available products?

@Nitin-Varma-Vegesna I think it's this one: https://store.3dr.com/mini-gps-ublox-max-m10s/

@Eric-Katzfey Ok, thank you!
-
@Eric-Katzfey Now, it arms successfully, even though it says Preflight Fail: heading estimate not stable and Preflight Fail: Yaw estimate error. Is this an issue?

@Nitin-Varma-Vegesna If you are just flying in manual or altitude hold modes then those shouldn't be an issue.

@Eric-Katzfey What about autonomous control indoors, and how could that be fixed if it's an issue? This is with a new GPS as well. Do I have to configure anything? Also, for the EKF2_GPS_CTRL, I reset to default: 7

Here is an image of when I start autonomous exploration (not flying yet) but moving it with hand, I am getting these preflight errors that I used to not get.
This is with SYS_HAS_GPS, and SYS_HAS_MAG to 1, EKF2_MAG_TYPE = Automatic, EKF2_GPS_CTRL = 7
Also, voxl-inspect-gps is saying NO GPS for fix type:
dt(ms) |fix type|Sats|Latitude(deg)|Longitude(deg)| Alt(m) |Vel(m/s)|HorErr(m)|AltErr(m)|
129.5 | NO GPS | 0 | 0.0000000 | 0.0000000 | -17.0 | 0.00 | 4294967.295 | 4092465.408 |^C -

@Eric-Katzfey I would rather not delete everything outside of /data/, is there a way to reset the params of px4 another way? This issue only happens when I start exploration, and I move the drone up with my hand slightly, but why do I get FCU: Vision Failure.

@Nitin-Varma-Vegesna You can set parameters via
voxl-configure-px4-params. -
@Nitin-Varma-Vegesna You can set parameters via
voxl-configure-px4-params.@Eric-Katzfey That is what I did to reset the params prior to this happening.

@Nitin-Varma-Vegesna Well, that's why I asked you to do the full SDK installation. If you install the SDK and set it up as we do from the factory then it should be working like when you first got it. If it doesn't then that potentially points to some damage caused by the crash and not some configuration change you have made since then.
