Just not having luck with DJI stuff this year, old stuff that worked fine last season, new stuff I'm just setting up, I can't get anything working with out a hitch and a lot of hassle, I'm pretty stumped on a few of the issues. I feel like I'm getting out of my league, eventhough I've flown DJI sinve the phatom 3 in 2015. Had 11 DJI aircraft in all and never has any issues until now.

Trying to set up the o3 air utnit with a Pavo 20, goggle integra and FPV controller 2
everything is bound green lights all around, but I can't start the motors.

Uplug cool down, try again, same.

So I hook it up to betaflight and no action on the transmitter sticks and switches,  it says vtx Table not set up, which is one of the same problems I am having with my controller 1 airunit o1 goggles v2 set up.

what is worng??? with the VTX?

There is no VTX table set up in betaflight, same for my older air units, the new firmware updates or updating betaflight must have done something because they all worked last year.

How do I know what which one is the appropriate VTX file for my country and my VTX model is?

The VTX panel is for analog VTX. Forget about it.
Do you see the OSD in your Goggles?
Have you selected the SBUS receiver in the Receiver panel?
And if you move the sticks, could you see the bars move in that panel?
