Got my Air day before yesterday......charged all batteries and awaited morning to start registration and all that stuff. Yesterday morning, connected using my Kindle 10 HD 2017, did all updates, and all went well. Got my bird all registered , let it set on my deck, going through a bunch of settings for flight and camera stuff.......all was good...no flying!! Later, in the afternoon, I received the Nexus 7 (2013) I ordered as a dedicated controller monitor for this setup. D/L GO4, connected immediately........all good, no fly, as too dark by now. This morning, Finally went flying!! Had great 1st flight, learning controls and camera settings, etc.........ran out of battery WAY to soon, was having great fun!! Shut down.........recharged batteries..........ready for round 2, right?.........Now can't get A/C and controller to connect.....tried everything I could think of.......different sequence power on/off of controller and drone, deleted and reinstalled GO4 ( though that shouldn't affect controller to A/C bonding), did all the GO4 app connection instructions....nada......cant get the controller to connect to drone....any ideas?
