Hi Tamas, this video is how to get the voxl2 running with HITL: https://www.youtube.com/watch?v=ysvpJdXFWaM&ab_channel=AscendEngineering

Also - unless you are running the voxl-dev branch, then you will not be able to do a SERIAL connection from the voxl2 to QGC, you can only leverage a UDP connection. If you are running the voxl-dev branch and flashed the board, then you can leverage the voxl-px4-hitl executable and connect to QGC. However, you cannot have gazebo open simultaneously because the serial connection will then be interrupted.

If you wish to run HITL while running QGC, then run this using an FTDI cable and then turn on the required services (voxl-vision-px4, voxl-mavlink-server) and then connect to gazebo serially, and QGC via UDP signal.

Let me know if this makes sense.

Hi @Tamas-Pal-0 - looks like you are correct in that the voxl-px4-hitl has not been pulled into voxl-master. I would recommend for now switching over to the voxl-dev branch and running with the steps through there. Once it has been pulled into voxl-master, then you can recompile, reflash, and run through it on that branch. Other options as well is you can copy the file voxl-px4-hitl from the voxl-dev branch into your current working voxl-master, recompile, and reflash the voxl2 with the newer firmware containing the correct executable.
