Hello,
I have an APM 2.0 that connects fine over USB. Radio calibration in the GUI doesn't. All bars show zero/gray activity. Movement on any of the channels will not produce anything. GUI calibration isn't picking up anything.
If I run radio calibration in the CLI it seems to show something normal.
Setup > Radio calibration gives me all channels with averaging very close to 1100 | 1950
If I run the Test > PWM it appears all channels are moving smoothly between 11,000 and 19,536
When I run the GUI calibration every channel is exactly 3000 | 0
If I go to the Flight modes area, the mode CH5 is unresponsive and stuck at 0.
Again inside the CLI, the modes test seems to work fine toggling between certain modes that I can assign different modes at certain ranges using the controls on the radio.
The main HUD is showing disarmed if that helps. No response. I recall before I did an update the HUD was working great even with nothing connected to input/output. It wasn't showing disarmed on startup and I could move the APM around and see it moving on the HUD. I've tried disconnecting everything like before but still nothing on the HUD.

I'm apparently having the same problem as well.
I have the following setup:
- Spektrum radio AR400, (I've also tried Spektrum AR8000)
- APMega 2.5+
- Arducopter 2.9 Quad
- Mission Planner 1.2.32 (I've tried 1.2.28)
When I first connect to the APM using MissionPlanner10, I see the "Connecting MAVlink" retrieval of values from the APM on my screen work just fine.
I am able to download code and use the CLI to interact with the APM and see that the printed results of the "setup" then "radio" radio calibration are:
1: 1091 | 1892
2: 1092 | 1892
3: 1091 | 1896
4: 1092 | 1891
5: 1551 | 1152
6: 1497 | 1498
7: 1497 | 1498
These values all seem reasonable given what I've read in the forums for a 4 channel receiver. The GUI radio calibration shows no happiness, an completes with the exercise with the defaults 3000: 0
I've put a servo on the various outputs of the radio and they individually work well, controlling the servo.
I've put a oscilloscope on the APM inputs with the receiver connected to the APM and the signals look the same as when just connected to the radio - the PWM signal changes with changes in the transmitter controls.
I have two problems as far as I can tell -
1) the Planner GUI won't calibrate the radio in the APM (just as the original poster describes: no green bars moving)
and
2) the APM outputs 1-4 (corresponding to the 4 inputs) all have a simple square wave signal out of 1ms "on" and 1ms "off" instead of a PWM signal.
Thanks for any help!
John, I'm having the exact same problem you described here. How did you fix this?? Thanks!
Does anyone think this should be in the APM software section?
It's difficult to tell if this is a software or hardware issue.
