Hello,
anyone tried to use Java to connect to Wiimote trying a JSR-82 implementation like avetanaBluetooth?

I'm facing some problems, not really sure what channel I should use in the URI ( "btl2cap://xxxxxxxxxxxx:?) to connect and send/read data. Any suggestions? I succesfully connect to channel 1, but nothing happens whe i send data.

My code looks something like:

I haven't tried the java bluetooth libs, they seemed too messy. Maybe you should look for a HID class?

Thanks for your answer. Have you got something in mind? I can't find anything usefull supprting BT HID in Java. That's why I tried to send the data directly via L2CAP, if only i could connect to right channel.

I am working on a Mac, i should add.

HID is pretty abstract whether the connection is via bluetooth or usb. just find a java api for sending and receiving HID reports.

OK, so there seems to be none. At least not a free and finished one.
The Problem is, for using BT in JAVA you need also already need a lib implementing the suggested API (JSR-82) and bridging this to the underlying system. For MACs the only one is avetana which is based on BlueZ.

A BT HID lib for Java now base relay on JSR-82. As far as I can see, there is no such thing, except some not ready HID2go API and a Linux based USB HID.

I had a quick look at the Python script here at wiili, and it looked like it is just opening 2 connections to Channel 0x11 and 0x13 and is sending byte arrays over those connections. I'm just wondering if there has to be some handshaking before, in order to open this connections, as i only can connect to channel 1.

Maybe the BT lib I'm using has a bug. Or maybe I am doing things completley wrong. Dunno.

But thanks for your help.

I have done this, exactly the way you planned to do it: using the avetana JSR-82 implementation.

I switched over to using Python instead, as only very few people seem to have a JSR-82 implementation on their J2SE system. But using Java definitely works, just the way you said: By opening two connections on channel 0x11 and 0x13 - one for sending, one for receiving data.

If you don't manage to figure it out yourself, I can post the code in a few days. I just reinstalled my OS on a new hard drive, and I currently can't copy my old files to the new hard drive as I only have one SATA cable so far.

Wow, that would be to awesome.
Maybe avetana is a little wobbly on the Mac?
Or I have some bug in my code.
Anyhow, if you had it running, that would
exclude all possibility of doubt if I
could test your code. Thanks.

Anyway, good luck with your system.
