I have a project that I would like to use the Wiimote on however, I would like to use the Wiimote without a PC, using a microcontroller instead.

Has anyone tested the I2C port on the Wiimote to see if you can get the IR camera information directly? Or does anyone have any other ideas on how to interface the Wiimote with a microcontroller? I know you can directly interface the Nunchuck to a microcontroller, but I have not found anything that allows me to receive the IR camera data via I2C.

Clange: No dice. As far as I know, you can add an extension, but that extension can't get data, it can only have data read from it. If you the remote open and mess around with its innards in the right way, you might get it to happen, but I wouldn't advise this. Bluetooth is the best way to connect.

Thanks for the replies. Bummer! Big time...

Does anyone have experience with Bluetooth modules and microcontrollers?

Well ive looked into this but i cant seem to find a bluetooth module that lets you do l2cap connections (needed for wii remote) they all seem to do rfcomm which is useless for this, the only other thing i can think of is using a pda and let it do the processing.

Another way would be to use a usb bluetooth adapter which has a physical serial port on it and connect that to a microcontroller but you would need to write everything from the HCI level up!

I did find these two modules:
PearlBlue: emxys dot com
YBM-1200:

(I cannot post URL's yet!)

You have to register on emxys website to view the manual for the PearlBlue. However, There is a reference to L2CAP in the PearlBlue module's manual. It is a picture that shows the architecture of the module with an L2CAP layer. I am going to email the company to see if it indeed will support L2CAP.

What does everyone think about interfacing these modules to the Wiimote?

Yeh check and see, but looking at the PealBlue_Fact_Sheet.pdf it looks like it only support the serial port profile, alot of them seem to say we support l2cap because rfcomm is a profile on top of it.
