Pixhawk is not sending chanels into QGroundControl

Posted by Tom on May 23, 2018 at 5:22am

Hi,

I have a problem with new Pixhawk. When I connect it to QGroundControl via USB, pair it with transmitter and bind it, I get no channels at all, like in image: 3691368003?profile=originalIt is strange to see channels out of channel borders.Calibration is not working, position of sticks have no effect.

Parts - radio is working correctly (it works in PC quad simulator via USB). Receiver is binded and working (lights are in correct colors (:) and plugged into Pixhawk RC IN. Pixhawk should be fine, it can be calibrated into compass and accelerometers. I tried PX4 firmware too, no change.

I'm out of options, last resort will be reclamation - but i takes ages. Does anyone please have any suggestions how to fix this?

    You have the cable miss-wired.  The Yellow wire should be one slot over so that going  from right to left  you have Black, Red, Blank, Yellow, Blank..

    The spot where you have the Yellow wire is the INPUT for S.Port TELEMETRY from Pixhawk.3702428233?profile=original

    Sure the Pixhawk could be bad, but I have doubts about that which is why I'm focused on the receiver, how the receiver is setup, which firmware you are using on the radio and receiver, and especially how you have the receiver connected to the Pixhawk.

    I want to see pictures of how you have the receiver connected to Pixhawk.

    Pixhawk cannot be bad themselves?

    Pixhawk should be fine with either S.Bus or CPPM, so either you have the input cable 180 out, there is an open between the Signal wire and the Signal pin on the RCIN port, or the RX is just bad...
