Hello guys,

I am new to Pix4 and QGroundControl, right now I am facing a problem that the channel signal is not stable. Jump between its desired level and 0.

I used analyze window and found out this situation:

But it didn’t happen at first time, and once after I reassign channel on the transitter, problem shift from channel 3 to channel 6, so I dno’t think it’s a hardware issue.

I also tried rebind and reset all parametters. Not working.

Any ideas would be appreciate.

Thanks.

What PX4 software version are you using? What hardware are you using? What receiver are you using? How is it connected to PX4? Have you checked the wiring? What have you changed since it was working?
