Difference is that hdmi is a HD video, other input is SD only. Not sure if gimbal cable carries HD.
I have a problem on my air unit: my sbus (dbus) cable is broken, the pins comes out of plastic case.
Please check on your cable how is connected. I'm sure that the brown cable is on right pin...
I'm interested to understand the communication from lb and flight control. I use lb on a cablecam, and I have a cc3d board with my firmware for control. I wish send info from my board to ground by telemetry channel. Best is also change icon and name on ground system but this require a complete...
Dear friend, as you don't have hdmi cables (I have a lot...) I don't have the USB ttl adapter. I ordered one on eBay but I'm still waiting. So, I can't help you but after all take cate to have led Green!
Hi gaucho, on my air unit when I connect hdmi cable and switch on the camera the led from red became green. I don't have a go pro, but a gh4 but I'm sure that there are no difference.

About TTL, the adapter I'm waiting for have a jumper to switch from 3.3 to 5 volts.
Now the problem is to be sure if is your tablet the problem, or if something don't work in repaired unit.
My unit work, I tried today.
Have you a TV or monitor with hdmi in? Many times, a PC monitor with a digital input DVI and adapter is working.
The cable is a mini-HDMI to HDMI, or by adaper. I have all here, but my unit is working (just arrived back).
Later I will test and try to connect my phone and my tablet.
I assume that...
Strange combination, I received today my ex-fault LB unit. DJI sent me a NEW ground unit (I'm sure that is new because is in the box dedicated to the ground units alone), no repair. Tomorrow I test it, but now I know that if something happen there is the solution.
