Hey guys, I have a phantom 2 vision plus and I'm currently in Italy. The first couple of days it flew no problem. Now it barely flies. I get solid flashing green lights on the bottom and when I go to start it it flashes red fast. On my dji iPhone app it says the drone is at -8.5 feet in height when it's literally 4 feet below me. I assume the drone needs to be plugged in and re calibrated but I don't have my computer available. I'm using someone else's computer and I downloaded the assistant and PC assistant and for some reason the drone won't connect. anyone have any idea on what I can do for a quick fix?
