So if I understood you correctly, you connected both the aircraft and controller, but only recognizes the aircraft?i do not have the cable provided by dji but i do have other usb to micro usb leads which i am trying none of them seem to be doing anything .I am plugging the micro usb into the handset and the usb end into the laptop as i did with the drone
it sits there for a few min and then the handset starts to beep but nothing happens in the assistant app to show it is connecting .
Edit: I beleive that the board with the usb plugs is either damaged or not connected correctly. This is why you are able to fly your drone, but can't see anything in the screen.
