IR Mode in WiiRemote lib stops working

[Anonymous]

Hello,

I am making use of the WiiRemote library within Xcode on a Mac (lion), I have managed to pair with the wii mote, however when I try to start the IR mode by calling , I get initial output in the debug log which looks promising and shows long output consistent with IR output (based on running the DarwiinRemote app in debug), but then after a while it stops outputting the long string and the only X and Y values I get are -100 and -100 respectively.

What am I doing wrong here?
