I'm having the same issue. Haven't even flown it yet. Bought mine used, with an older ipad. First challenge was getting the dji go simulator to work. After I found the empty box in the corner and clicked it the simulator worked fine. Did some bench testing with the props off and everything was ready to go. Later that night I decided to get some more simulator time. Turned on the Go app, turned on the TX, and before I could even turn the drone o. The red light started blinking and the beeping alarm went off. Tried several times to get it to work and nada. This morning I tried again, everything worked fine. Took it out for the maiden flight- bad compass. Had to drive a mile from where I was to get the compass to calibrate. Everything looking good, I switched on the sim to show my dad how it worked. Then I closed the sim and selected camera in the GO app. Wouldn't connect, said something about how the sim had already run? Props wouldn't start. So I cycled everything off/on. Transmitter error again. Tried restarting several times with no success.
For such an expensive piece of technology I'm pretty far from impressed.
If I have to try and download new .bin files I will try. Not much of a computer guy over here.
