@Chad-Sweet I haven't tried. However, I manage to get it working by doing a factory reset configuration of the VOXL2. Don't know why it made a difference though.

Hi All,

I can't get QGroundControl to connect to the internal PX4. I ran voxl-vision-px4 to setup the mavlink connection. voxl inspect shows the following.

The voxl-vision-px4.conf shows:

and the IP is correct. Nothing shows up at the QGroundControl client side.

@Chad-Sweet I believe this is what I need. Thanks.

I am wondering if anyone have experience using a Futaba RC system instead of Spektrum with the VOXL2?

Hi ModalAI, I have not yet acquired a VOXL2 board, but we are in the process of planning our new avionics roadmap. In this context, I need to know how log files are retrieved if VOXL2 is running the PX4 on DSP.
