PX4 Params Lost

[SMRazaRizvi]

Hi, I recently flashed my Sentinel drone, and apparently, the files under /data/px4/params are missing.

How can I recover the following factory default params files for the Sentinel drone:

parameters_gyro.cal
parameters_acc.cal
parameters_mag.cal
parameters_level.cal

I have tried calibrating the Compass using QGC, but it doesn't perform accurate calibration, and unless this issue is resolved, I cannot fly up the drone.

Please help.

@SMRazaRizvi What do you mean that compass calibration is not accurate?

[SMRazaRizvi]

@Eric-Katzfey

I mean, even after calibration, my drone constantly drifts toward the back. Any clue?

[Eric Katzfey]

@SMRazaRizvi The compass provides heading information. Having a poor calibration on the compass wouldn't cause the drone to drift.

@Eric-Katzfey
I see. What can be the reason then?

@SMRazaRizvi Do you have any trim settings on your controller? The level calibration could also affect

[SMRazaRizvi]

@Moderator How can I check the trim settings?

[Moderator]

have you posted your PX4 logs to logs.px4.io for analysis?

[SMRazaRizvi]

@Moderator Yes I did.

@SMRazaRizvi Can you please share so we can try to help you? The logs should help diagnose why it is drifting
