pixhawk refusing to arm after ESC calibration

Posted by Tommy Chheng on February 22, 2014 at 10:03pm

I'm swapping my 3dr quadcopter's APM 2.5 to a pixhawk.


I'm able to get through all the setup, and even the ESC calibration.

As the last step of the ESC calibration(http://copter.ardupilot.com/wiki/initial-setup/esc-motor/), i'm able to use my Spektrum dx6i transmitter to 

  1. If the long tone indicating successful calibration was heard, the ESCs are “live” now and if you raise the throttle a bit they should spin. Test that the motors spin by raising the throttle a bit and then lowering it again.

Then I set the throttle to min. and disconnect the battery. I wait 30 secs, plug the battery back in. I pull my throttle to the lower right for 5 secs and the main light turns green, so I pull the throttle back to the center min position.

Now, nothing happens if i raise the throttle at all. 

After a few more seconds, the main light turns back to a flashing blue.  I can pull the throttle back to lower right and the main light will turn green again, but nothing happens.

Any ideas what's wrong?

    Got the same problem with my PIXHAWK firs time setting it up with EMAX 25A 4in1 ESC.

    Were you able to figure it out?

      Sorry I have not been able to determine what to do after the arming stage...

      Anton, have you been able to get help from 3d robotics?

        Never raised a support ticket with it. falling back on spare single ESCs as i need a functional drone ASAP. Tested EMAx with MWC autopilot, works like a charm. also tried dropping the refresh rate on ESC signal, no difference.. can't justify putting more time into it.

    Any ideas if i'm missing a step? I emailed 3d robotics support last week but I got zero response so far.
