I have been through thte forum and attempted every fix for the controller, including the c1 c2 buttpn reset, conecting via usb and micro usb niether will recognise on any phone i own and will not recognise on pc to do firmware update, it will charge no problem but that is the only wired conection it will recognise, is this common issue where the controller just all of a sudden stops connecting  drone can still be flown via wifi and what is the last resort fix or do i bin it and buy a new controller
