How exactly can I use MAV_CMD_DO_SET_SERVO command in QGC?

[minominium]

Hi all. I hope you had a nice summer.

I open this issue because I need to use servo motor in mission mode, but it doesn't work..

this is what I want to do, especially moving servo motor in waypoint mission.

I use SG90 servo motor with additional voltage regulator, and set signal pin to AUX OUT 1.

and in mission command, I set param1 : 1, param2 : 1300

The servo motor is working fine with controller in manual(or stabilized) mode, but I need mission mode.

So what I need to change or set? Any reply will help me :)

QGC : 3.3.2 in windows
PX4 : Latest stable
Frame : 450 sized custom quad

Hello!
Maybe this pull-request will help you?
And any your opinions on the question "What's the real use case for DO_SET_SERVO? Would we be better implementing a couple higher level commands? payload, gripper, etc" will be very useful.
Thanks!
