Is there any current limitation that I am not aware of, for the do set servo command on channels from 9 and above? I only found a topic (See below) that might be related, from copter forum.
I know that mission planner not showing the status of these channels is a Mavlink1 limitation. However I am not talking about status, but actual control. However not mission command control, but control via mavlink.
If I use RC and send PWM on any of those channels in the s-bus stream and I can use them for control and even servo RC pass-through, Whatever I am controlling works from RC. However if I send command from mission planner or other Mavlink (DO_SET_SERVO) then nothing happens
No mater if I set servo function to 0 or to 1.
Can someone please kindly check if they all get the same results. Any channel from 9 and above. Then use command set servo on that channel. Does it register on the AP side? Can you control a servo on Ch9 with sending Do_Set_Servo and if moves the servo. Agian, I do not mean put command in mission, but to use servo control inside of MP (see picture) or other means of Mavlink message to do it.
In my case we are sending Mavlink command (buttons pressed on ground control station), over telemetry, so that is why it is not a mission command.
I am sure a lot of people do not use these channels, especially not for such functionality, so that could explain why it is not so obvious.
I found these on relating matter, I know copter gets all the love, so could be related:
Any help is appreciated.
