[Bluez-users] Bluez build problem

[Voni Hakau]

Hi all,

I'm cross compiling bluez-util to my platform, so I use something like
--prefix=/path/to/my/platform/root/filesystem/usr. Everything builds
and installs perfectly.

But, in my platform, bluez now thinks that all the files are located
in the path /path/to/my/platform/root/filesystem/usr (it is hard coded
in the binaries), which doesn't really exists on the platform - it was
just on my host, where I built my root fs for the platform. I need to
install everything on my host to that path, but on the platform I need
bluez to ignore it...

Any suggestions ? I can always use --prefix=/usr and then manually
copy all the files to /path/to/my/platform/root/filesystem/usr but
that is too hard... there must be a better way..

Thank you!
Voni

Hi Voni.

Try to create a package instead. Use --prefix=/usr when you configure, 
but use DESTDIR=/tmp/buildplace when you install.

That should install the files to /tmp/buildplace. Use tar(1) to create a 
tarball of the files in /tmp/buildplace, or even better, use a packager 
for your preferred platform.

During configuration, your command line might look like this:

make --prefix=/usr

When you "install" the package, you'll use this command:

make install DESTDIR=/tmp/buildplace

Obviously, the files won't be installed to the right place. No problem, 
use tar(1).

cd /tmp/buildplace
tar czf /tmp/bluez-x.xx-i386.tar.gz *

Now you have a tarball that you can install wherever you wish, including 
the correct place for your platform, 
/path/to/my/platform/root/filesystem/usr.

Good luck.

[Bluez-users] Error encounter when connecting A2DP following wiki instruction ! How to connect A2DP ?

[colorant]

Hi

    I try to connect earphone with A2DP on arm board .
    I follow the instruction from 
http://wiki.bluez.org/wiki/HOWTO/AudioDevices

    I encounter error while doing connect saying connect method does not 
exist !

    This is what I did :


~ # ps
  PID  Uid        VSZ Stat Command
  .....
  271 root       1576 SW< /sbin/udevd --daemon
  445 root       1884 SW  /bin/sh /etc/init.d/rc 2

   string ":1.1"

~ # dbus-send --system --type=method_call --print-reply --dest=org.bluez 
/org/bluez org.bluez.Manager.ActivateService string:audio
method return sender=:1.0 -> dest=:1.9

~ # dbus-send --system --type=method_call --print-reply --dest=":1.1"

Error org.freedesktop.DBus.Error.UnknownMethod: Method "Connect" with 
signature "" on interface "org.bluez.audio.Sink" doesn't exist


So I have following questions :

1 . Anyone can help to point out what might be wrong in the above operation 
?

2. Actually I also try the method of modify the /etc/asound.conf to add the 
bluetooth and use aplay directly to play the music, that way also not 
working!

~ # cat /etc/asound.conf
pcm.bluetooth{
        type bluetooth
        device "00:02:5b:00:c1:a0"
        profile "auto"
}
~ # aplay -D bluetooth sample.wav
Segmentation fault
~ #

What might be the reason ? I can do aplay sample.wav to speaker. So alsa 
utils should be ok.

3. I notice that , on this howto, it do not mentioned the process of 
pairing, Shouldn't that be done in some other place ? How can I done that ? 
actually I have put in hcid.conf something like :

# HCId options
options {
    ....
        security auto;
        pairing multi;
        passkey "1234";
    ....
}

But this one do not work for dbus-send method , right ?

Thanks.

Raymond

Hi

    I am try to connect A2DP with Bluez

        passkey "1234"; // I use my pc with usb dongle to provide the a2dp 
service, so this is set to1234 not 0000 or 8888 etc.
