Has anyone been able to configure a Pixhawk to work with a lightbridge HD link?
I'm able to get the Lightbridge control signals to the pixhawk but I've yet to figure out how to set the FailSafe. When I turn off the RC controller, the lightbridge air module continues to output the same S.Bus channel signal levels.
From talking to others I've found out that Lightbridge outputs the fail-safe "flag" in the header or footer (I'm not sure which) of the S.Bus signal (not the normal PPM channels like the pixhawk is expecting). Can anyone confirm this is true and if so, how can I map the DJI Lightbridge failsafe signal to the Pixhawk's failsafe.
I would also like to figure out how to rig a lightbridge like system onto a non-dji UAV.
We've been using dji exclusively so far, and are hoping for some more flexibility than diu can offer. Now that we've used lightbridge though, don't know if we can go back. It's pretty sweet, especially for our applications (looking at baby trees close-up, from far away).
Teradek Clip and similar is much better, with lower latency.
but of course I do understand that you would save some money, unfortunately I don't have a "lightbridge" to reverse engineer it.
Have you tried Solo with SoloLink? Now 2,500ft with HD video
I wish those things would be available as a standalone addon for operations where Solo is just far too small.
Absolutely +1 Andre.
Yes, I fly a Pixhawk Skywalker and a Dropix tricopter for about half a year with a DJI Lightbridge. Works really well and RC link is at least as good as a standart 2.4ghz transmitter.
You set the failsave in the DIJ Lightbridge app to your values. To test them you have to arm Ardupilot first (secure the props...!).
+1 for the standalone module.
But it seems 3dr`s investors are not that keen on diy products so we have to wait until there is finally a working raspberry pi style implementation.
What about the Connex from Amimon ? http://connex.amimon.com/
Any experience or opinions ?
Having remote control and HD video in one all-in-one link is certainly nice. It concerns me though that lightbridge and especially sololink is essentially normal wifi, which probably cannot compete with the robustness of frequency hopping 2.4GHz RC remote controls. I would be more at ease with using a robust 2.4GHz FHSS remote control and having HD video and telemetry over a wifi link.
Hi Chris, are you using Lightbridge 1 or 2?
Thanks for the response!
I've figured out that I need to use the Android App, The Iphone app is different and wont' let you do this (at least on the LightBridge 1). I'm planning on getting an Andriod device soon so I can try this (I only have an Iphone at the moment).
In the DJI Lightbridge App, does it let you configure which channel the FailSafe is sent out on? How does the Pixhawk get/interpret the light-bridge's Failsafe signal?
