So I've been gone from the site for a while. Haven't flown the phantom for nearly a year. Got it out and charged it all up. Went to use the DJI GO app for the first time and the controller does not seem to be communicating at all with my iphone 6. Controller is GL300A. I've searched the web but haven't had any success in fixing it. DJI GO only says "how to connect". When I first tried it I had fill control of the P3P but no communication with the phone. I tried installing the firmware via USB flashdrive onto the controller but it doesn't seem to do anything although the light on the flash drive does light up when plugged in. Tried multiple cables and both my iphone 5 and iphone 6. I've wiped my phone and reinstalled the DJI GO app several times. No luck. I've tried to roll back the firmware of the controller via the app but when I go there it shows as not connected. I'm running iOS 9.3.4. the P3P is on 1.09.0060 and I have no way of seeing what's on the controller. Any ideas? It seems as though the USB plug on the controller may have failed but it worked fine when put away. Really wanted to use the P3P over the weekend.
