Cannot connect QGroundControl to internal PX4 (VOXL2)

[mlarsen]

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.

Can you ping 192.168.1.214 from the computer that you are running QGC to make sure there is proper network connectivity between the two?

@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.
