I recently bought headphones that can use the so called "high quality audio profile" in bluetooth.
I noticed a lot of ppl are asking bluez developers to support it.
any news on that feature?

Did you try to use them?
Did you read http://bluetooth-alsa.sourceforge.net/ about A2DP?

I am not saying they will be working, but unless you try...

Sorry but I am still stuck with getting the headset to work.
I mean it did work, but now it just screems about can't getting a rfcomm channel. so, I posted to bluez list:
http://sourceforge.net/mailarchive/forum.php?forum_id=1883

as for using the headset with skype, I notice that running /usr/bin/skype is a script that tries to use Esound.
Now according to bluetooth-alsa.sourceforge.net one sould kill Esound to use the headset.

SO, we need to alter /usr/bin/skype to work with alsa-oss, this way:
1. make sure alsa-oss is installed in your pc
2. edit /usr/bin/skype to have this:
#!/bin/bash
#
# Wrapper script to run Skype with sound wrapper when possible
logfile="${HOME}/.Skype/skype.log"
progname="skype"
progpath="/opt/${progname}/"
progopts="--resources-path ${progpath}"
shellcheck1=` which artsshell 2> /dev/null `
shellcheck2=` which esd 2> /dev/null `
artsdcheck=` ps x | grep artsd | grep -v grep `
## We use ps ax for esd as esd can be used globaly for all users.
esdcheck=` ps ax | grep "esd ." | grep -v grep `
skypecmd="${progpath}${progname}.bin"
wrapsound="yes"

[ -d "$(dirname "${logfile}")" ] || mkdir "$(dirname "${logfile}")"

echo "===== " `date` " =====" > ${logfile}
#Going to "homedir"
cd ${progpath}
echo "${skypecmd} ${progopts}" >> ${logfile}
echo "=========================================="
${skypecmd} ${progopts} >> ${logfile} 2>> ${logfile}

if [[ $? -ne 0 ]] ; then
echo "Running wrapped Skype failed, trying not-wrapped mode..."
echo "=========================================="
skypecmd="aoss ${progpath}${progname}.bin"
${skypecmd} ${progopts} >> ${logfile} 2>&1
fi

exit $?

I basicly throw away the esd and arts part, then told skype to load by OSS , but use alsa-oss.
this way alsa would be used.

PostPosted: Fri Jan 13, 2006 2:32 am    Post subject: dbus needed for current hcid Reply with quote

after a day or two, I finally tracked down the reason nothing worked: dbus was not running.
therefor hcid didnt load
there for no bluetooth device was talking proparly

At /etc/init.d/bluetooth
I added the line: need dbus
before the line : after coldplug

I am very new, should I post a bug ?


1. I am using a bluetooth USB adaptor named: billionton V1.1 P/N USBBT02-B (has the CSR core 02) the barcode reads 6 45988 25000 1
2. I can hear music on my logitech mobile freedom V1.2 (also worked on a V1.1 in the past) via btsco.
3. I can hear music on my CC&C Technologies, Inc BT-MINI-HS (picture is here: http://www.geeks.com/details.asp?invtid=BT-MINI-HS ).
I also managed to hear high quality audio (A2DP) on them

I'm not quite sure if you should file a bug or not, weren't there extra startup scripts for that? well, i do suppose it'd be better to post one and have devs erase/ignore/deny it if you feel it's a bug.

either way, about throwing out esound/artsd:
it's likely that this isn't what you'd want to do. esound and artsd provide software mixing *on top of other drivers*. that means that esound and artsd will use alsa drivers to communicate with your sound card (or your bluetooth headset in this case). the problem is: unless your sound card can do hardware mixing and the driver knows how to do this (which i doubt is the case with those headsets) (yes, i know alsa can do software mixing too, but dmix never worked properly for me), you can't play more than one sound on the same device. this wouldn't normally be a problem in this case since you would probably play system sounds and music on your sound card through normal speakers while the only program using the bluetooth headset would be skype, but then again, wouldn't it be nice to be able to play music on your headset while skyping? after all, that's what you bought a headset with the high quality audio profile for, isn't it?

PostPosted: Mon Jan 16, 2006 4:01 pm    Post subject: Must use ALSA in kernel ? Reply with quote

Kalin: I am using net-wireless/bluetooth-alsa-utils-0.2_alpha20060104
Today I read that some thing concering oss emulation in alsa was fixed in the recent release.
So I followed the gentoo alsa guide and switched to use alsa-driver.
If I try to emerge the ebuild I get:

SND_HWDEP is not set! Plese select a config like SND_USB_AUDIO or
SND_EMU10K1; see under Drivers|Sound|ALSA, see inside PCI or US
B

I use usb-audio fine via the alsa-driver. ovcurse it doent appear in the kernel .config

How can we fix it?

OK I am certain now. bluetooth-alsa cant work when using alsa-driver. Even when SND_HWDEP is included.


I cant use BT-alsa when I compile alsa as modules in the kernel.

I dont understand the difference.

Is it to do with new alsa-driver ?

If you have problems, please report:
Code:

uname -a
equery l alsa
gzcat /proc/config.gz |grep SND_|grep =

Some of that may not work with your environment (`emerge gentoolkit` is needed for equery), but try to provide info on your kernel .config

Giys, plese be more specific when you report problems anywhere, not jsut here:

0. What did you want/try to achieve?
1. What did you do?
2. What happened?
3. Any additional thoughts, configs, info.

PostPosted: Mon Jan 23, 2006 2:38 am    Post subject: Logitech Mobile Freedom HS02-v07 on ISSC USB Dongle works :) Reply with quote

After two nights I got my headset to work :)

btsco gave me all kinds of erros "Permission denied", "Function not implemented", "Connection timed out" etc. (btw, btsco <MAC ADDRESS> -v -i hci0 works for me, btsco2 <MAC ADDRESS> does not !!!)

Removing the content of /var/lib/bluetooth and setting up /etc/modules.d/alsa properly helped a lot. I already thought of buying a new dongle because I read some posts that the ISSC chipset is not well supported and the output of hciconfig hci0 revision was not very promising:
Code:

I can recommend the Logitech Mobile Freedom for Linux Users. It works like a charm now and the quality is far better than in Windows (tried it there first with the shipped and the widcomm bluetooth stack)

Also got skype running without problems (like the postings above already say: don't use any sound daemon and enter the right dsp device (/dev/dsp1 for me))

Here's my /etc/modules.d/alsa to make my posting complete:

Code:

I'm trying to get a Nokia HS-11W to work with skype. But having some problems with the xmms test.

Code:
dan@chrono ~ $  btsco2 00:08:C6:60:51:30
Device is 2:0
Voice setting: 0x0060
RFCOMM channel 1 connected
recieved AT+CKPD=200
opened hwdep
Can't connect SCO audio channel: Protocol not supported


Then if i press the volume buttons I get
Code:
recieved AT+VGS=7
Sending up speaker change 7


But when I set xmms to play to the bt headset, the track doesn't play it stays paused on zero.

Any ideas guys?

i'd suppose your dongle isn't supported... what's the output of

Hello.

I am having problems setting up this Plantronics M2500 headset with a Belkin Bluetooth Version 2.0 dongle in Linux.
My output running btsco2 is:
./btsco2 00:03:89:77:6C:E0

Device is 1:0
Voice setting: 0x0060
RFCOMM channel 1 connected

Then after pushing the headset button:
recieved AT+CKPD=200
opened hwdep
connected SCO channel
Setting sco fd
Done setting sco fd
recieved AT+VGS=15
Sending up speaker change 15

Then I run Skype for example and when I try to make a call for the /dev/dsp1 device I dont hear any sound and I have the following error message from Skype:
write error, written = 256
write error, written = -1

When I do hciconfig hci0 I get:
hci0: Type: USB
BD Address: 00:00:3A:68:C0:C7 ACL MTU: 1017:8 SCO MTU: 64:0

TX bytes:1618 acl:62 sco:0 commands:33 errors:0


Can anyone give me any idea?

Thank you very much.

Regards, Antonio.

well, i've got a sitecom with 100 metres range, that seems to work fairly well, but i can't remember the version of the thing :(

madureira: the good news is, i know the headset *can* work, the bad news is, i'm clueless as to your problem :)

Just to tell that i've got it working. :D
I've been testing with bmp and when the musics end btsco complains with:
Quote:
Can't connect SCO audio channel
: Software caused connection abort

I tested it with alsa and oss. A funny thing is that i can't hear online radios... weird, i guess...

It's not a big problem for me, as i only want to use my headset Logitech HS02-V07 with skype. Just hope that Gaim-vv gets stable soon ... :D

@madureira:

What does

hciconfig hci0 version

tell you?

I also found this post https://forums.gentoo.org/viewtopic-p-1821952.html#1821952. Quoting elduderino
Quote:

you should try a different usb-dongle. your SCO Mtu is 64:0 it must be 64:<0 like 64:8 or something to work.


You can set the SCO MTU manually or by modifying your kernel. I found something on that on one of the bluez mailing lists, but didn't work for me, so I forgot the link. It may work for you. On the other hand, if your dongle is Broadcom-based, you better get a new one. I have a Broadcom-based thingy, working fine in Windows (after changing to Widcomm-stack), but no good in Linux.

Marcell wrote on the BlueZ ML that he is to look into the broadcomm compatibility issue.

However boardcomm are common in BT V.1.2 dongles , and now that V.2 is out - I belive it makes more sense developing in that direction.
After all , BT dongles are so cheap today, one may find a dongle that works fine in linux for 15$.


Did any1 actually managed to run beep media player with A2DP ( a2play ) ?
I tried to follow the advise , and een posted in the BMP ML , but it doesnt work.

Hello.

Thank you for your replies.

I didnt manage to put it working yet. I have seen a patch to change the sco_mtu in the alsa project webpage to be applied in a hci_event.c file. I have bluez libs 2.25 installed in my PC but I dont have this file. Where should I apply the patch then ?

I am needing this dongle for a research project, so I need it working surely and quickly. Can anyone tell me which dongle works for sure with a Plantronics 2500 headset ?

I also need to develop an application to automatically connect to the headset. btsco2 does this but it seems to stop if the user tries to disconnect the headset (stop the RFCOMM). So my idea is rebooting everything when the user closes an SCO link and starting again btsco2 as soon as the headset is in range again. Which steps are needed to reset the headset connection (killall btsco, hcitool dc, ... ) ?

Thank you very much.
