Can’t connect O3 air unit with dji googles V2

[Roberto88us]

Can you be more specific about what problem you're having? It sounds like you're saying the O3 powers on when you plug in a USB, but it's not powering on when you power on your quad. Is that correct?

Correct! it doesn't power on when battery's on.

Correct, the 03 module only powers on when the usb-c its plugged. On battery only wont work

Check the red and black wires on the cable between the O3 Air Unit and your Flight controller. If that's good, use a volt meter and verify you have power.

I recently had an issue where my GPS unit wouldn't work in the quad. Worked perfect when I hooked it up externally. When I removed the cable, I found the issue. Either the TX or RX pin wasn't locked in place and pushed out when I plugged it in.

how should i set the multimeter?

Set the meter to VDC. You should read between 9Vdc to 24 Vdc depending on your flight controller and battery. Be careful not to short your meter leads together.

The easiest way would be to disconnect the cable and measure on the side that plugs into the O3 and a ground anywhere on the flight controller or on the back side of the connector on the flight controller where the O3 cable plugs in. Both are tricky spots and not really for beginners. You're losing power to the O3 and it's either not coming out the FC or the cable is open.
