Ubiq_01 points out this vid demonstrating the use of a wiimote over iPhone’s bluetooth connections –

The video first shows the iPhone’s AirPlane mode activated before starting an OpenGL-ES Demo. In the demo, the orientation of the virtual WiiMote is controlled by a physical WiiMote over a Bluetooth connection. For this demo, the portable Bluetooth Stack from the BTstack project was used.

The OpenGL-ES code was based on the excellent tutorial by Simon Maurice. Thanks, this is my first OpenGL program.
