How to setup external magnetometer (TinyRTK has none)


is it necessary to reset all params before using a new external magnetometer?

i have following problem. i use the drotek tinyrtk module which has no compass. the pixhawk’s magnetometer is influenced by the PDB on which it is placed.
i have connected an old neo 8 gps module to telem2 and the compass to i2c. Does the px4 recognize the new compass automatically? because qgroundcontrol doesnt show any new compass. or do i need to do the calibration again and then it will be shown?


If you add an external mag you need to redo the mag calibration.

yep. thanks!

i thought it would appear in parameter list after boot. but how you said. the parameters appear after calib.
