Connecting Pixhawk Mini 4 to Spektrum Receiver

Hello,

I have a Holybro QAV250 with a Pixhawk Mini 4 controller, and I’m trying to pair it with my Spektrum receiver. According to the Pixhawk wiring guide online, all Spektrum DSM/DSMX signals should go through the RC IN port on the Pixhawk. There are 2 cables provided for DSMX receivers (shown in the image)

Previously I had a FlySky receiver. I only needed to plug in the servo male plug to Channel 1 of my receiver and the PPM port on my Pixhawk Mini 4 without any encoder, and I could easily perform radio calibration through QGroundControl.

However, it doesn’t work for my Spektrum receiver even though I used the cable with the servo male plug to the RC IN port on my Pixhawk Mini 4.



Do I need to plug it into XBUS or SRXL2 ? To make it even more confusing, theres another SRXL2 port that is the same as the bind port (accepts the standard servo male plug). I’d appreciate any help

Hi Jian,

did you find a solution? I face the same problem now.
