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
454 root 1964 SW /bin/sh
554 root SW< [krfcommd]
563 messagebus 1944 SW /usr/bin/dbus-daemon --system --fork
566 root 1416 SW hciattach -s 921600 /dev/ttyS1 bcsp 921600
573 root 1564 SW ./sdpd

~ # dbus-send --system --print-reply --dest=org.bluez /org/bluez

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"
/org/bluez/audio org.bluez.audio.Manager.CreateDevice
string:00:02:5B:00:C1:A0
method return sender=:1.1 -> dest=:1.10
string "/org/bluez/audio/device3"
~ #
~ # dbus-send --system --type=method_call --print-reply --dest=":1.1"
"/org/bluez/audio/device3" org.bluez.audio.Sink.Connect
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
