I was able to get the cable to work.
All of the create functions in the app are working and the record/shutter works too.
It sucks to take the camera off the gimbal and remove the cable and then have to put it all back together for gimbal use so I'm hoping for the usb cable in the future.
Pauxier, we apologize for the inconvenience caused, our engineers are working on developing the USB shutter control, please pay attention to our website about the future release, thank you.
