Hi,

there is a some driver for SCO using ALSA. Does anything exists for good old 
OSS too?

the complete SCO/eSCO stuff needs to be reworked, but I don't see any
future for an OSS driver. ALSA is the choosen architecture for 2.6 and
onwords.

Well, so implementation from:
http://www.dcs.gla.ac.uk/~jp/snd-bluez-sco/

will never be included and you want write your own implementation?

I don't want to do this, but we have to, because of Bluetooth 1.2 and
eSCO etc. The other point is, that the snd-bluez-sco driver should be
integrated directly into the SCO module and not running as a kernel
thread, because there is no need for it. However I actually don't know
how this all should look like and work together with the Headset and
Cordless Telephony profiles. And what about A2DP which carries audio
streams over an ACL link?

Regards

Marcel

[Bluez-users] Bluez and headset

[Daniele Primon]

[-- Attachment #1.1: Type: text/plain, Size: 1259 bytes --]

Hello list. I'm moving first steps with bluez to pair a Nokia BH-100 Cell
phone to use it with VoIP application such as Skype. I'm a Debian user but
at the moment I'm configuring it on Ubuntu Gutsy. Kernel version is
2.6.20-16-generic which include standard bluez support and also has
snd-bt-sco module. The distro comes witch bluez-btsco package at version
0.50 and bluez-utils, at version 3.19. Following the wiki instructions  (
http://wiki.bluez.org/wiki/HOWTO/AudioDevices) pertaining to my utils
version lead me to pair the device. I've tested with aplay -dbluetooth
somefile.wav as indicated but heared only noise. Moreover, wengophone nor
alsamixer detects the device leaving my stuck at it.
Do I have miseed something?
So I tried with the 'old' way, by loading snd-bt-sco module and using the
btsco app, i've been able to have aplay and wengophone work as expected  but
yet still missing mixing. That way would be sufficient to me but I realized
that the btsco has to be restarted if the handset device becomes
unavailable. I think that it should be quite easy to have it started
automatically upon need (and maybe the kernel module reloaded too) - i.e.
when the handset becomes available again. Where should I look for this?
Thanks,
 Daniele Primon

[Bluez-users] BlueZ and Headset

[Mahtab Hossain]

[-- Attachment #1.1: Type: text/plain, Size: 2464 bytes --]

Hi,

I have a Nokia HDW-3 which has been used with btsco successfully before in Fedora 4. Now, it seems I can't somehow pair it.

Here is my hcid.conf file look like:
options {
        # Automatically initialize new devices
        autoinit yes;

        security user;

        pairing multi;

        # Default PIN code for incoming connections
        passkey "BlueZ";
}

hcitool scan or inq can find the headset. And I also have successfully paired with my Motorola Mobile Phone (entering PIN at both Phone and Laptop side) - so I think pairing can be done with the current state of my bluez stack.

The hcidump -X -V always gives me the following results whenever I try to connect with my headset or run some command like, hcitool info <bt-addr of headset> or send direct command like CreateBonding through dbus or even when I switch-on my headset (I wonder why my dongle wants to connect with the headset since I have not saved any information of my headset in the Laptop).

These are my current bluetooth packages:

It would be really helpful if somebody can point me somewhere why the pairing isn't happening.

Thanks

Re: [Bluez-users] BlueZ and Headset

[Mahtab Hossain]

[-- Attachment #1.1: Type: text/plain, Size: 5017 bytes --]

Dear users,

The problem of headset not pairing was there because my Nokia headset had reached its upper limit on the number of pairings. :)
By going through the headset's manual, I could delete all the stored pairings there in the headset and now it can be paired alright with my Laptop.

But still I am not successful in making it work. Whenever I turn-on the headset, it is automatically paired with the Laptop and I see an ACL connection being established like this:
 > ACL 00:03:89:B0:58:91 handle 42 state 1 lm MASTER AUTH ENCRYPT SECURE

When I try to play song using mplayer, it stops right before "playing" for a long time and I see lots of SCO packets flying (saw it through hcidump) like below:

> SCO data: handle 45 flags 0x00 dlen 48
    0000: 6b 00 6e 00 35 01 7e 01  03 01 cc 00 65 00 71 00  k.n.5.~.....e.q.
    0010: f9 00 51 01 6e 01 17 01  48 01 0e 01 37 00 b8 00  ..Q.n...H...7...
    0020: b0 00 63 00 a1 00 55 00  d5 00 aa 00 3e 00 d8 00  ..c...U.....>...

After sometime, mplayer fails to play with this error:
[AO_ALSA] alsa-lib: pcm_bluetooth.c:1179:(bluetooth_cfg) Error 22 while configuring device
[AO_ALSA] Playback open error: Invalid argument
Could not open/initialize audio device -> no sound.

But I see the SCO packets moving still in hcidump window. I see two connections at this time:

< eSCO 00:03:89:B0:58:91 handle 0 state 8 lm SLAVE 
 > ACL 00:03:89:B0:58:91 handle 42 state 1 lm MASTER AUTH ENCRYPT SECURE

The SCO packets goes flying until I turn off my headset or disconnect. Even if I turn off my headset, I still find this connection with "hcitool con" command:

Connections:
< eSCO 00:03:89:B0:58:91 handle 0 state 9 lm SLAVE 

Would really be helpful if someone explains to me about what is actually going on here.

My .asoundrc file looks like this:
pcm.bluetooth {
        type bluetooth
        device 00:03:89:B0:58:91
        profile "auto"
}

I finally could make Nokia HDW-3 work with Fedora 8 by applying the patch listed in this mailing list.

At least everything is fine at the moment though I get the following error while playing (it still plays fine) -

[AO_ALSA] alsa-lib: pcm_bluetooth.c:417:(bluetooth_hsp_hw_params) Protocol not available (92)
