Pixhawk Mini - sensors problem

Hi all.
I have been working with the pixhawk1 for quite a long time, everything worked weel.
Now I was trying to achieve the same results on the pixhawk Mini, but I am having many problems:

  • cannot calibrate compass
  • cannot calibrate level horizon


  • I’m using Qgroungcontrol (tried both windows and ubuntu)
  • tried different firmware versions: v2_defalut, v3_default, developer stack, v1.7_stable_release

nothing seems to fix the problem
any help ?
