Detected 0 Channels. To operate PX4 you need at least 5 channels

Contributor I

So, I bought the KIT-HGDRONEK66 recently.
Following the different steps, everything goes fine until the 'radio' section configuration in QGroundControl.

The software doesn't seem to detect any channels. I double-checked the setup, tried S-bus and I-bus configs, and made sure the RX is bound too.

This is for a project with a tight schedule so any help would be appreciated.

thanks for your time

To operate PX4 you need at least 5 channels" PPM receivers that have an individual wire for each channel must connect to the RCIN channel via a PPM encoder like this one (PPM-Sum receivers use a single signal wire for all channels)

I had the same problem. I went into the Aux. Channels tab in settings on the transmitter and made sure to assign all of the channels. eg. Channel 5 - SwA  Channel6- SwB. I also made sure that the output mode was PPM, the serial was S.BUS, and the controller had the newest software version. (Found in GitBook) 

Hope it helps.

For what is is worth, I am having the same SBUS related issue, but it is working with PPM.  I am not using the radio system in the HoverGames kit, but the system I am using has the ability to configure outputs as SBUS, PPM, etc.  I cannot get the FMUK66 to recognize the SBUS signal, but it works just fine with PPM.
