"Hi Jakub,
Finaly got some time to have a look at v0.5 and it would be nice to impelment your "continues rotation servo" routine there. I've forked arupilot https://github.com/SCUBA82/ardupilot.
We could work there if you want to. Adding a third…"

"Servo_test mode seems to be work fine on v0.5. Thanks Randy"

"Hi Jakub,
Did you fix your "oscillation issue" too?? Would be interested on what you've changed... so please scare me and show me your coude :-) Cause I've also some changes (Servo Test Buttons) in my code to merge."

"Hi Jakob,
You've modified your servos to "continues rotation" so the parameter "on/off servo" is correct.
I've also seen this kind of oscillation of my axis. In my case it's an issue of servo trim. I have to recalibrate the servos (little poti…"

"We are talking about "Antenna Tracker" where UART2 (telem2) is prepared for a second radio (also on APM2.X boards). Having bluetooth und telem2 and 3DR radio on telem1 works like a charme on my  APM 2.x. The problem is the other way around.
The idea…"

"Thanks for your replay but thats not the case.
The Telem1 provides the uart rx,tx connections as well as vcc and gnd. There are several tutorials on how to connect peripheral devices to telem1. I'm going to take a deeper look at this but I'm afraid…"

"So.... finaly had some time to switch my bluetooth module to TELEM1 port and my 3DR radio to TELEM2. Guess what: the bluetooth is not working on TELEM1. I've also tried connecting a FTDI adapter to TELEM1 but no connection with Mission Planner. Both…"

"Issue #799 "Antenna Tracker Extended Tuning: Remove Proxy Mode drop-down" seems to be fixed in current Mission Planner 1.3.20!"

"Another part to mention:
It seems that on/off servos are allways driven on their full speed. So it makes sense to set your servos "min / max" values lower than they could be. By this you get slower but smoother movings."

"Yep, as I said: the trim/test button part is the only thing that I've changed. What's up with your ch2_out value? Does it change?
Maybe I'm gonna try some "position" servos on my setup this weekend. Perhaps I can reproduce your Problem."

"At least you should be able to move your pitch servo with the "test slider"... (I hope so..)
I've seen you are using "normal" servos in your setup...
Have you taken a look at the status values "ch1_out" (yaw) and "ch2_out" (pitch)? They show you…"
