Hi,

on a machine installed with Ubuntu 7.10 I could not pass the accelerator callibration in WRLImpl.java. I tried in on my machine wit Ubuntu 6.06 LTS and it works well with my BToes 2.0 EDR device.

Ubuntu 7.10 uses libbluetooth2 but 6.06 uses instead libbluetooth1. Maybe this could be a hint.

Anyone with Gutsy (Ubuntu 7.10) gotten WiiRemoteJ to work yet? I'll try using an older bluetooth library and see if that helps...

[Perry3D]

I have the same problem. I'm also using Gutsy.

I have compiled libbluetooth.so.1.0.24 (same version as in dapper) but it doesn't work. Maybe i'm doing something wrong.

Does anyone have a solution?

There is a bug in avetanaBT.

I was working on my on WiiRemoteJ version just to get my java skills up. And than i ran in to same problem and fix it.

I will share it so it will work for WiiRemotej.
Assuming you have the avetana source and know howto compile.
Here we go:

go to your avetana source directory,
in /de/avetana/bluetooth/stack/BlueZ.java
somewhere at line 317
change line

int receiveMTU=672, transmitMTU=672;

to

int receiveMTU=-1, transmitMTU=-1;

do a 'make clean'
make sure your envvariables are correct
do a './install'
copy the files to your WiiRemotej dir

and there you go GO GO...

=======

The problem with the avetana was that when you open a connection the LCAP protocol does some handshake things.

avetana : I request a config
wiimote : Ok set your MTU size on 185
avetana : I am ignorant so i'll use MTU size of 672
wiimote : See Yaa

after fix

avetana : I request a config
wiimote : Ok set your MTU size on 185
avetana : Ok setting MTU size on 185
wiimote : nice doing business
avetana : blabla
wiimote : blala
etc..etc...

and thats it.

Excellent. Good work finding the fix. I'll add it to the WiiRemoteJ tips sticky!

Hi,

This bug does not seem to be specific to avetanaBT. I am using an svn BlueCove and BlueCove GPL 2.03 snapshot and I get the same pause at the accelerator calibration. I am also using Ubuntu 7.10 system.

I had to apply a similar work around to get it to work, specifically, hard code the receive and transmit MTU values to 185 on lines 62 and 63 to BlueCoveBlueZ_L2CAP.c (located in src/main/c of bluecove-gpl svn trunk)

This is far from the ideal solution. I just started working on WiiRemoteJ the other day and I know nearly nothing about bluetooth so I haven't tested how this may affect other functions.

So is this an Ubuntu or BlueZ issue?
