Android

 
Used with a Google Nexus 7 pad.  Bluetooth Device mode=Mouse, Keyboard, Combo or Gamepad, Authentication Mode= 1, Connection Mode=Pair. 
 
The Quadstick can also be used with a USB OTG cable and get power from the Android host instead of using Bluetooth and being powered by another source.  The catch is, the Android device will not accept external power while in this mode (unless Rooted and running special software), so both the Android device and the QuadStick will get their power from the device's battery.  It's useful for portable situations, but for a more permanent setup, powering both and connecting via Bluetooth works better.
