Re: External MAVLink Connection using VOXL 2 through ttyHS1

Hi,

I am in need of integrating a mavlink gimbal and a parachute with the voxl2 autopilot. Mavlink is becoming a common protocol to communicate with a number of external peripherals like gimbal, parachute, engines etc. As such, there is a growing need to have voxl-mavlink-server be able to start a bi-directional mavlink stream on app UARTs like that on the USB3/UART Add on board (/dev/ttyHS1).

Is this something on the roadmap? Or any work arounds at the moment?

Thanks.

@h3robotics This is the first request we've had for such a feature. It shouldn't be too hard to add that feature into voxl-mavlink-server. All of the fundamental pieces are there. It is open source and we accept PRs. If you would like to add that feature yourself and submit a PR for it that would be great!

@Eric-Katzfey I would love to contribute!

I tried setting up voxl-cross. The pre-build version of voxl-cross is v2.7 on the downloads page. But I see that the voxl-cross in the repository has reached even v4. So I wanted to build voxl-cross myself. Unfortunately, the instructions say to download these files from the modalai downloads:

ubun1.0_1.8.04-M0054-14.1a-perf-20250421-rootfs.tar.tar
ubun2.0_2.0.0-perf-20250421-rootfs.tar.tar

And I can't seem to find these files. Without that, I am unable to compile. Any suggestions on how to compile the latest voxl-cross? Or should I just use v2.7?

Thanks.

@h3robotics I'd just try with v2.7

@h3robotics I've been using v2.5 on my development machine and it works fine so v2.7 should also be fine. (Dang, I need to update )
