Dear,
Thank a lot for this video but I need to disable a internal magnetometer (Revolution). When I select Mag usage : AuxOnly
The software send me a warming for a big difference between both magnetometer.

The onboard magnetometer is used as reference for Auxmag orientation setup.

If you select "AuxOnly", the only mag used for navigation/ins13 is external

Revolution don't exist, except for Chinese cloners.
CC3D and Revolution refers to two different boards.

OKay for this informations.
I need to modify firmware because I really need to use a external magnetometor in all mode.
Thank you
Best Regards

Why you want to modify ?
What do you mean with all modes ?

[StephaneCERVETTI]

I would like control the position of UAV. I have create my own gps. I think it's more accuary (somes centimeters) than the orignal gps. I use a same protocol that DJI GPS and compass.
My first goal is a create a simple flight with a flight stationary with my own "GPS".

No need to modify, the naza Gps is already supported with his magnetometer.

okay, then ihave a big problem because when i connect a real dji gps, the card don't use it. When i move the dji gps, yaw keep the same value and if i move a autopilot this value change.
I will start a new setup.

Do you set a fusion algorithm that works with Mag ? Ins13Indoor for example.
Move the mouse over "source invalid", if i remember there is a tooltip.

Look video i posted above, how are the two mag alarms in Attitude > Magnetometer tab ?
