Hey,


i bought last week the DJI smart controller for my drones and first of all it is a amazing controller. After the configuration and updating process i was checking the FPV cabebilitys of the smart controller. My first test was a standard DJI Air Unit in my 5 inch fpv drone and it works fine.


I switch to my diatone cine whoop with a Caddx Vista system and it doesn't work.



My troubleshooting:
  • tested with various USB-C cables
  • use the lower nativ USB-C port
  • switch on and off the smart controller and the googles and connected in different sequence
  • arm the drone and hover

... but nothing works. After a while, i get very randomly a single frame. If the caddx vista is connected to the googles, i get a message in the googles ''low-power mode. Unable to record videos''. This happens also without connecting the smart controller.


Is this ''low-power mode'' cause my problems and is it possible to disable?
Have any one connect the googles with the vista to the smart controller without problems?


thx Jeff

Hey, same issue here. Smart Controller video output works on my 5" setup with regular DJI air unit. However I can't get a picture out of my little whoop with a Caddx Vista unit.
Is this a known bug, DJI?

Hey,
i have figure out a solution/workaround:
  • Switch the smart controller and the googles on
  • Arm the drone with the caddx vista system
  • Connect the smart controller and the googles via usb-c

If the drone is armed, the system isn't in the low power mode. I think the lower power mode is definitely the proplem.
In my opinion, it is only a workaround for this issue.

Can you fly the Air Unit or the Vista with your Smart Controller?

The smart controller is only for hdmi output from the dji fpv goggles. You can't fly fpv drones with the smart controller.

Low power mode is usually triggered by the air unit (DJI or Vista) being too hot. This triggers eventually on all of them if you do not have the motors running. The Vista heats up quicker, but this should not be a problem once you arm.

Thanks for your quieck response!
Have you tried binding it though?
Wish i could avoid the regular controller and go straight to the smart controller to safe cost.

thx for this information, but with this setup i get the video feed from the goggles, not directly from the caddx unit. In the goggles i get a solid video feed and this video feed goes normally (with the dji air unit) through the USB-C cable to the smart controller. In my opinion, this doesn't affect neither the air unit nor the caddx vista. If i land my drone and swap the batterys, i will need to disconnect all and start with my workaround… its a pain.
Also, it‘s not safe to arm a drone if you‘re not immediately ready to fly (play with your smart controller and a long cable near your normal controller ).

i doesn't tested this, but the gimbals from the smart controller are different to a regular "fpv controller". The neutral throttle stick position on the smart controller  is in the middle position. The neutral throttle stick position on a normal fpv controller is on the bottom and not spring loaded (except you will fly in 3d mode).
The FPV Live App is only a broadcast app and i don't think that the DJI Go 4 is compatible with the DJI FPV System.

That makes sense. The Throttle resolution would be a lot lower. Or the quad would be at 50% throttle. Which would be a very bad day.
Maybe its possible to hardware mod the controller to remove the spring and use full range. But cant be sure if it even binds at the moment.

Issues with goggles not recording isnusually osd not enabled in betaflight. Uart 1 2 3 one of them needs osd enabked depending on the system

Do you have any other two way osd working?

Osd is on screen display and its a two way connection when enabled with the msp tab.

The specific setting is msp in your uart section. It is a radio button. Uart 1 2 or 3 should have it enabled. It allows data to flow from the fc to the air unit. Without it your goggles dont receive the armed aignal.
