I can't get more than 1 remote to sense IR at the same time. My code looks something like this:

for (int i=0; i<2; i++) {
WiiRemote remote = WiiRemoteJ.findRemote();
remote.addWiiRemoteListener(this);
remote.enableContinuous();
remote.setIRSensorEnabled(true, WRIREvent.BASIC);
remote.setAccelerometerEnabled(true);
remote.setLEDIlluminated(i, true);
remote.vibrateFor(100);
}

The problem may have somethign to do with the exception that gets thrown when the 2nd remote connects:

21-Dec-2007 3:53:04 PM wiiremotej.WiiRemoteExtensionFactory registerWiiRemoteExtension
WARNING: Error registering extension.
java.lang.IllegalArgumentException: Code already registered!

at wiiremotej.WiiRemoteJ.findRemote(WiiRemoteJ.java:225)
at wiiremotej.WiiRemoteJ.findRemote(WiiRemoteJ.java:185)

Has anybody else run into this. Is there a solution?

Thanks,
Garth

Thanks for the pointer, but that code isn't working well. I am getting the same Exception, which I suspect is causing my problems. I turned on logging and got what is copied below. One thing I see that is interesting is the statement "FINE: is already connected." when I connect the 2nd remote. Is it somehow getting confused, thinking the 2nd Wiimote is the 1st Wiimote? This is all a guess, of course, as we don't have access to the source.

I realize now that the "is already connected" output is probably occuring when it notices the same 1st Wiimote a 2nd time. After that it does in fact find a new 2nd Wiimote.

The fact remains that the IR input is not working for multiple Wiimotes, and that one exception that keeps popping up is suspicious.

Thanks,
Garth

sorry for wrong point.
i have met the same exception
http://www.wiili.org/forum/2-or-more-wiiremotes-connection-t2483.html

with ignoring this warning message, two acceleration from each remote were well distinguished, but no try for IRSensor.

i think the IRdata can be distinguished too.

Thanks for the tips. I do get an instance of the Wiimote object by ignoring the exception. Unfortunately after doing so it seems enabling IR sensing has no effect. it seems either there is something strange with my setup, or IR sensing from multiple Wiimotes doesn't work with this library.

It _sure_ would be nice if we had the code available to us. It seems like development may have stopped, so I may have to move to some other project if we can't get the code.

Thanks,
Garth

Ack! I thought I had already put out an update correcting that. Blech. Sorry for my forgetfulness. The fix for that has been sitting on my computer for ages.

Anyway, I'll put out an update later tonight. Sorry for the inconvenience!

EDIT: Uploaded! You can obtain WiiRemoteJ v1.1 here. Standalone docs (which are included with the release) are here.
Note that I haven't had time to test, so please report any problems by starting a new thread (or posting to an existing one if it's an old bug). Thanks!
