I have a HTC Sensation phone, Google/Asus Nexus 7 tablet and an iPad.
iPad works fine. Sensation works fine.
Nexus 7 connects perfectly and I see the live stream coming from the cameras. However, on the Nexus I am unable to take off.
I have tried both the default FreeFlight app and the ARDrone Flight Pro app, and neither 'Launch' the drone. In FreeFlight I just get the 'Loading...' screen when I hit the Pilot button, in Flight Pro I get the camera feeds but there is no 'Launch' button so I cannot take off. I have tried with aeroplane mode both on and off and tweaked some other settings to no avail. Quite annoying.
This is version 2 of the drone - it is brand new.
