I am struggling with my first ArduCopter hexa project and right now I feel a litte down-hearted about my progress (lack of).
I have been able to fly it decently in Stabilize mode, but it´s oscillating in roll axis so there is definitely some PID tuning to do. So this day was dedicated to PID tuning and I was starting out with good hope.
But I did not get far, since I am not able to alter even ONE single parameter! I just keep getting this error message box (and similars):
And it does the same for ANY parameter I try to adjust. Error comes a few seconds after I click the Write Params button. (Clicking the Refresh Params seems to work as supposed to.)
I currently use 2.0.49 and Mission Planner 1.0.84.
Some moments ago I did a "Reset APM Hardware to default", hoping for that to make a difference. It did not. I use the Planner to upload firmware and to do the setup. Communication in general seems to work great between Mission Planner and APM unit,
As I also pointed out (in another recent forum post) I am totally unable do enter calibration values in the Mission Planner/Configuration/Setup/Battery tab. I wonder if that problem is caused by the same root problem, what ever that might be.
I attached a copy of my current parameter file.
Any more of you guys have this problem?
So what is wrong and what is the remedy?
