Herelink SBUS not being recognised by non-arducopter FC

(Chris Jackson) #1

As an experiment tried plugging in a Herelink to another flight controller, SBUS and Mavlink. Standard Mavlink messages are working, however the SBUS is being very odd.

SBUS channels 3/7/8/9/10/11/12 are being recognised, but the others are not.

If a Futaba Rx is plugged in on FC boot up, all channels are recognised from the Futaba, if its then removed and the Herelink SBUS hot swapped, all channels work.

I realise there is no support for non-cube installs, but there appears to be something a little non-standard with the herelinks SBUS output. Any ideas on what it could be?

Got a scope?

Interesting that only 1, 2, 4, 5, 6 are not working.

PX4 accepts it as well as ardupilot, and we know quite a few gimbals accept it fine.

#3

Is the other FC running Ardupilot or PX4?

Which fc?

Gremsey has no issues with HereLink normally. How is your setup done?
