Primary compass not found, mag inconsistent ! Pixhawk 4


Hello everyone !
I am getting “primary compass not found or mag inconsistent error by QGC”. It gets solved after I do the compass calibration especially via USB. However every time I connect my battery and do some bench testing I have to perform this step. Please can someone guide me regarding this !
Thank you !


Which version are you using? Can you try if this still happens with latest master?


I use stable 1.8.1. Yes I will try with latest master


I bet I am not the only person curious about this. @Vrinda if you have the time, could you please post your experience moving from 1.8.1 and head of master? Do you find that this behavior improves?


Does it mean that if you do the calibration with the battery only, the issue remains after calibration?
Do you reboot the drone after mag calibration?


Yes with battery the issue remains. Yes I do reboot !


@langrind , I will keep you posted :slight_smile:


Update: So currently, once I started flying the drone, it does not give me the error. Thus am sticking to stable 1.8.1
