hi all, I have a Phantom 3 advanced and the RC Model GL300C will not connect to the phantom, and has NEVER connected to the phantom since i got it 3 days ago. I've spent 16 hours trying to get this to work and im absolutely at my wits end. The status LED on the RC is ALWAYS red (and doesnt flash). from the moment i turn it on. The drone is on version 1.8.8, i tried to update it to 1.9.6 but it failed(it says in the logs there are errors i can link them if it helps), and it has not made any difference. According to the manual, the ALWAYS red LED means the RC is functioning normally, but is not connected to the drone. Okay then, i understand i must connect the RC to the drone... The main problem seems to be, no matter what USB cable or device, the RC/DJI GO app will not detect that there is a device attached. I have tried 3 different micro USB cables and 2 lighning cables across the following devices, and the DJI GO app does not connect to the RC at all (following the instructions in the quick start guide). I've tried: Iphone 6s running latest iOS Ipad Air 1st gen running latest iOS Samsung Galaxy S7 Edge Running Marshmallow 6.01 Samsung Tab 2 running android 4.1 Samsung Note 4 running android 5.1 Samsung Galaxy S3 running kitkat 4.4.4 When I plug in a phone/tablet to the RC and turn on the RC, the phone beeps and begins to charge, so there is definitely connectivity of some sort between the RC and device. When i run the DJI GO app with the cable plugged in all i get is the "how to connect" button, and when i follow the instructions on that and return to the equipment page according to instruction 4, all i continue to get is the "how to connect" button. I've tried the hard reset technique (C1+C2+shutter button on, off and on again) and it hasnt worked. I understand that i cannot connect the RC to the drone with first being able to get to the "connect to camera" screen. In terms of android, on each device, i have enabled debugging and tried each method of USB connectivity (charging, MIDI, Media etc). which one should i be using? The drone itself seems completely fine. its status LED is on green once it has fully booted, and seems to be idling waiting for the RC to connect (once i get the app working, then press the connect button on the drone, but i cant get into the "connect to camera" part to be able to connect the RC- ARGH!) I really dont want to have to send this drone back, i just want it to work. I've had it 3 days and havent been able to fly it at all, and wasted almost all of my weekend trying to google a fix to no avail. as you can imagine, im quite annoyed that ive spent £700+ on a drone that i have not been able to fly, and that has eaten my weekend :/ You guys are my last hope before i send it back to amazon, but i would rather it just worked.
