Bug#418221: wmgui: fail to autodetect my wii handset, "Error opening control channel"
I don't think it'll make any difference, but try the latest SVN version. Got a reply from the BlueZ folks, I think we may have found the problem, although fixing it may be another matter.

Aha - progress!
I actually commented 2 parts, now lets uncomment one of them and see what
happens.

Bug#418221: wmgui: fail to autodetect my wii handset, "Error opening control channel"
Hthis is a tricky one.
One other idea to try (attached). Make sure you have no other bluetooth
devices around.
I've posted the question to the BlueZ-devel mailing list, hopefully someone
has come across something similar.

Try this one. I added an error message if the device socket doesn't close,
and added a pause before the connect. I'm thinking perhaps the device
hasn't closed and cleaned up by the time wiimote_connect tries to connect to
it.
The addresses print out the same, so I'm thinking it might be the bluetooth
device state.

I'm fine with staying here. I need an explicit CC in addition to the

Bug#418221: wmgui: fail to autodetect my wii handset, "Error opening control channel"
First thing I want to see is the bluetooth address that it finds: in
cwiid/wiimote/connect.c (assuming 0.5.02), declare a char bd_str[18] in
wiimote_connect, then after line 85, add:
ba2str(&bdaddr, bd_str);
printf("found wiimote at %s\n", bd_str);
The output should match the address you get from hci_tool and lswm. I
suspect it won't.
Apologies for any errors, I can verify code and create actual patches when I
get home tonight (I'm on US EDT).
Do you want to continue discussion on this forum, or move to
http://abstrakraft.org/cwiid? Whatever is more convenient for you. If we
stay here, should I reply to you guys explicitly, or just the list?

Bug#418221: wmgui: fail to autodetect my wii handset, "Error opening control channel"
Package: wmgui Version: 0.5.02-1 Severity: important I ran into a problem with wmgui and wminput with the package I rebuilt for Debian/etch. It fail to detect the Wii handset. I have to give the handset ID on the command line to get it to detect it. With wmgui, I select File->Connect, press <1> and <2> on the handset and on the dialog, and then after a while, a popup dialog reports [ "Error opening control channel" - ]. I select , and a nother dialog pop up with [ "Unable to connect" - ]. If I start the handset from the command line like 'wmgui ', it work. With wminput, I get the same messages: [EMAIL PROTECTED]:~/src/cerebrum$ wminput Put Wiimote in discoverable mode now (press 1+2)... Error opening control channel unable to connect [EMAIL PROTECTED]:~/src/cerebrum$ I found the suggestion to add the handset ID on the command line in http://abstrakraft.org/cwiid/discussion/1/2/34>, discussing this exact problem. -- System Information: Debian Release: 4.0 APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18-4-686 Locale: LANG=nb_NO.UTF-8, LC_CTYPE=nb_NO.UTF-8 (charmap=UTF-8) Versions of packages wmgui depends on: ii libatk1.0-0 1.12.4-3 The ATK accessibility toolkit ii libbluetooth2 3.7-1Library to use the BlueZ Linux Blu ii libc6 2.3.6.ds1-13 GNU C Library: Shared libraries ii libcairo2 1.2.4-4 The Cairo 2D vector graphics libra ii libfontconfig1 2.4.2-1.2generic font configuration library ii libglib2.0-02.12.4-2 The GLib library of C routines ii libgtk2.0-0 2.8.20-7 The GTK+ graphical user interface ii libpango1.0-0 1.14.8-5 Layout and rendering of internatio ii libwiimote0 0.5.02-2 library to interface with the wiim ii libx11-62:1.0.3-7X11 client-side library ii libxcursor1 1.1.7-4 X cursor management library ii libxext61:1.0.1-2X11 miscellaneous extension librar ii libxfixes3 1:4.0.1-5X11 miscellaneous 'fixes' extensio ii libxi6 1:1.0.1-4X11 Input extension library ii libxinerama11:1.0.1-4.1 X11 Xinerama extension library ii libxrandr2 2:1.1.0.2-5 X11 RandR extension library ii libxrender1 1:0.9.1-3X Rendering Extension client libra wmgui recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
