Strange result in Dynamic calibration

Postby Dju » Fri Jul 11, 2014 2:43 pm

Hi guys,

I did with success the static calibration of my board.
After that, I did the dynamic calibration but somethning is strange, the MAE still begin at 4.2 more or less and after several loops, the numbers of the columns grow up really really quickly. I did the Calibso dance on a football stadium, without any metal button, or phone ... and I did it each time in more or less 6min.
I try to use the a low variance but it's always the same thing.

I attache the aq-log file and this is screenshoot of my curbes..

0.488458 0.255353 2.781065 0.000000 0.000000 = 3.524876

did you try using the variance option? i had trouble with my calibration MAE going up and down until i tried the adjusting the variance. from there I was able to get a good MAE and finish up the calcs.

post your logs
Are you using aimu or dimu ?

If this is AIMU, I recommend running the calibrations with a copy of QGC 1.3. The later calibration utilities seems to have issues with AIMU MAG (eg. my logs which worked before, now don't). I can't promise that's the issue, but it's worth a shot.

Yes, can confirm, that the latest cal & sim is not working with AIMU MAG.

Hello again.

I made dynamic calibration few times, but in all cases when I did 4b stage I received error:

It is mean that I need to made Calibso again?
