Hexo plus copter Pixahawk problem,

HI, I have a Hexo plus hexacopter that always starts with this error message although the parameters and connection seems fine. It always sats PreArmCheck: HEX FFFFEOOO.

Does anyone know if this value indicates anything or if a part has failed?

Any help massively appreciated.


Moved to COPTER. What version of FW is this?

Its the HEXO PLUS 4.4 FW FROM SQUADRONE. I think they have customised and rebranded the Pixahawk device? Not sure what the Ardupilot/ pixahawk FW is tho.

I also get a constant “unconnected” message in the “control” plugin even though MAVLINK is connected and shows current parameters etc. What has to be connected to rectify this please?
