Hello everyone. I have looked all over the web and can't seem to find a solution. My old controller happened to get broken so I bought one off ebay. I had a solid flashing red light and beeps constantly. I have tried connecting my phone to the controller but they won't talk so I can't pair the controller and the drone through the DJI go app. I tried manually doing it by pushing the c1 and c2 and record buttons at the same time but the beeping over rides it. If I hold the return to home button I will make the sounds like it wants to pair but the flashing red light on the drone never turns green. I don't know if you can even buy a used controller for a drone. If anyone has any suggestions on how to fix this please let me know. Again I have the phantom three professional. The controller I bought says model gl300A on the back.
