What's the internal USB port for? (the one behind the status LED)

    The status LED light (the one that blinks green if all good) has a white cover that can be snapped out to reveal the LEDs behind it. Right next to those LEDs, there's a micro USB port. We tried to mess around with it (it required a custom-made/wrecked micro USB male plug), but we can't really tell what it's actually for. Yes, of course it's for testing or maintenance by DJI, but we can't really tell how to interact with it at the moment. We suspect there's some custom tool or application used in DJI factory that communicates with it.

    The exact way to communicate with the external port was easy to figure out because we already have the DJI Assistant software and we can intercept the USB traffic, but with this one we don't have any information.

    Anybody has some concrete information about it? Would be much appreciated.

    Well I'm curious to what the port is for as well but I don't have my manual on me. It's gotta be in there.

    The P3 has an SSD slot for the camera on the gimbal board access photos+vids. It also has one for P3 Mainboard to accesses the 4Gig SD card that holds the raw flight data. It could be the same on the Mavic to access the raw flight data for analysis.
