As you can see in the video below I'm not able to arm ESC with the switch :
I don't understand why because the green flashing led and the white flashing led are supposed to indicate that are ok to armed ESC ...
And the following message appears on QGC :
Which is impossible as when I press the switch button it doesn't work ...
I have the pixhawk 2 and the last version of QGC.
My RC was turn on.
Anybody able to help me?
