Today I received a Sensor Error message!  I had no problems with the flight. Do I have to worry!

Hello and good day trepacho. I am sorry for the trouble this has caused and thank you for reaching out. With regard to this matter. Please try to update the firmware of your DJI Mavic Mini to the latest version and please calibrate the IMU and Compass of the said drone as well to isolate the issue. Please keep us posted for further assistance. Thank you and have a safe flight always.

As far as I observed, the "Sensor error" appears when the GPS signal gets too weak during the flight. I'm not sure whether it is a correct interpretation, but this is what I connected the warning to when flying.

Thanks for the replies!  I'm with the last firm (0.4)!  Compass and IMU calibrations have also been made!

I love my mavic cuz if this error be careful

I'm almost sure this is because of poor GPS reception.

hiya,

i see 11 satellites and 5 bar for reception, so guess that Sensor Error is not for any GPS fault.

Upload your flightlog, mayby that gives the explanation.

cheers

Yes,

May i advice to do some after take off checks.....

The start of this flight was 100% up and 100% forward, if any serious error ( i.e. compass)  is at take off you will no notice that or too late.

cheers
