hi all... i noticed that information in the first post are very old... i wolud to know if i need bloetooth-alsa for using the bluetooth headset mic with bluez 3.24... if not... how can get my mic headset working with bluez3.24??? Speaker work very well with mplayer (not with amarok).


Since the bluetooth driver was removed from the kernel, using a bluetooth headset has become even more experimental. Bluez is using the new alsa API, but few applications are prepared to share information through that. I had a very limited success with mplayer some time ago, and documented it here. I haven't tried since, maybe it's better now. Please share your experience with us if you have any success. The Bluez trac is also an invaluable resource. Good luck! :wink:

i thought about sharing my experience... but also i would to have a completely working headset with mic :D... i finally got working speaker following the gentoo wiki... and usig the kdeblutooth progam set... not so hard... my bluetooth headset it's a g2comm (not very expensive headset ;) )... i think i will put this information on the wiki...
no one know if need to use the alsa-bluetooth libs for the mic?

Finding this statement really helped me:
Note: you will not need bluetooth-alsa, plugz, btsco or the like for audio to work. They are obsolete.

Hi everybody, I realized this is the right place for my post:

https://forums.gentoo.org/viewtopic-t-704681.html

Do you have any ideas?

PostPosted: Tue Jan 13, 2009 2:32 pm    Post subject: It is still possible to use a btsco even with recent kernel! Reply with quote

I have recently turned back to btsco for it is IMO much more reliable than new methods. Besides, I'm on amd64 — skype and ekiga don't work with newer methods (ekiga requires patched pwlib/ptlib and skype — binary alsa-bluetooth libs to be compiled e.g. from 32-bit chroot).
Thirdly, I haven't found a way to intercept headset key press without btsco and I use it to answer/drop calls in both skype and ekiga. If you want to use those scripts, see here: https://forums.gentoo.org/viewtopic-p-5385014.html#5385014

Here is a brief howto:
1. patch your kernel
you'll need following patch for 2.6.28:

btsco-2.6.28.patch

2. Configure your kernel to use old version of HCI USB driver. My config looks as follows:
Code:
cat .config | grep CONFIG_BT
CONFIG_BT=m
CONFIG_BT_L2CAP=m
CONFIG_BT_SCO=m
CONFIG_BT_RFCOMM=m
CONFIG_BT_RFCOMM_TTY=y
CONFIG_BT_BNEP=m
CONFIG_BT_BNEP_MC_FILTER=y
CONFIG_BT_BNEP_PROTO_FILTER=y
CONFIG_BT_HIDP=m
CONFIG_BT_HCIUSB=m
CONFIG_BT_HCIUSB_SCO=y
# CONFIG_BT_HCIBTUSB is not set
CONFIG_BT_HCIBTSDIO=m
CONFIG_BT_HCIUART=m
# CONFIG_BT_HCIUART_H4 is not set
# CONFIG_BT_HCIUART_BCSP is not set
# CONFIG_BT_HCIUART_LL is not set
CONFIG_BT_HCIBCM203X=m
CONFIG_BT_HCIBPA10X=m
CONFIG_BT_HCIBFUSB=m
CONFIG_BT_HCIVHCI=m

compile your kernel as usual.

3. Add ebuilds to local overlay, emerge them and start the whole running as shown here: http://www.gentoo-wiki.info/Bluetooth_headset#Obsolete_method_2

Hi erikderzweite!

your post makes me very happy in this moment, because I was just giving up my bluetooth headset after many unprofitable attempts to connect it to my amd64.
I'm trying to patch my kernel but I heve some little problem doing that.

These are the steps I've done:
I copied your patch into a file (such as /usr/src/snd_headset.patch);
Code:
cd /usr/src/linux
cat ../snd_headset.patch | patch -p1 --dry-run 


and this is the result:

Code:
can't find file to patch at input line 3
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|--- include/sound/core.h.orig   2008-12-16 23:31:29.000000000 +0100
|+++ include/sound/core.h   2008-12-17 00:04:50.000000000 +0100
--------------------------
File to patch:       


What's going on? I always patch kernel sources in that way, but now it seems to not find such a file that is present!

Thank you.

fbcyborg, try -p 0 instead of -p 1:
Code:
cd /usr/src/linux
 cat ../snd_headset.patch | patch -p0 --dry-run

Thank you very much,

it seems to work now!
Code:
# cat ../snd_headset.patch | patch -p0 --dry-run
patching file include/sound/core.h
Hunk #1 succeeded at 29 with fuzz 1.
Hunk #2 FAILED at 381.
1 out of 2 hunks FAILED -- saving rejects to file include/sound/core.h.rej
patching file include/sound/typedefs.h
patching file include/linux/pid.h
patching file kernel/pid.c
patching file include/linux/sched.h
Hunk #1 succeeded at 1833 (offset 4 lines).
patching file kernel/signal.c
Hunk #2 succeeded at 1940 with fuzz 1.

Only one question: I can read "Hunk #2 FAILED at 381.". Is it a problem??? I guess something didn't go in the right way.

What kernel do you use? The patch is for 2.6.28-gentoo (vanilla should work too though) 2.6.27 is a bit different:

btsco-2.6.27.patch

I have just tested the first patch on newly installed 2.6.28-tuxonice kernel
Code:

cd /usr/src/linux/
cat ../btsco-2.6.28.patch | patch -p0 --dry-run
patching file include/sound/core.h
patching file include/sound/typedefs.h
patching file include/linux/pid.h
patching file kernel/pid.c
patching file include/linux/sched.h
Hunk #1 succeeded at 1833 (offset 4 lines).
patching file kernel/signal.c

Offset is not a problem :)

IIRC, the patch provided at http://www.gentoo-wiki.info/Bluetooth_headset#Obsolete_method_2 forks for kernels up to 2.6.26

P.S. should perhabs add a wiki entry some day...
P.P.S is there a way to put longer code in a compact codebox with scrollbars?

Reply to P.P.S.: I don't think so.

Thank you. I use gentoo-sources-2.6.28.

there must be some formatting error then: I have made a clean install of gentoo-sources-2.6.28 and my patch works fine. If I copypaste the code from my topic, I get all kind of errors. Will try to figure that out.

EDIT: just apply -l or --ignore-whitespace to the patch command
Code:
# cat ../snd_headset.patch | patch -p0 --dry-run --ignore-whitespace

I that doesn't work, try remerging the kernel.

One more question.
I emerged btsco and btsco-kernel successfully.
What method do you use/prefer, to connect your bluetooth headset? I tried to use /etc/init.d/headset init script but it seems to not work.
I also tried to manually pair my headset using btsco, and it's OK even though I didn't a mplayer test to hear some sound.

Thank you for your support.

I use custom script which runs btsco -v BD:AD:DR:ES:SS and turns my bluetooth dongle off after I turn the headset off (I hate that blinking :) ).
Code:
#!/bin/bash
sudo hciconfig hci0 up
btsco -v XX:XX:XX:XX:XX:XX
#It might be not necessary to disconnect explicitly but it won't do any harm
sudo hcitool dc XX:XX:XX:XX:XX:XX
sudo hciconfig hci0 down

I launch the script in command watch plasmoid on kde4 (good to have some verbosity). Headset script didn't work for me too, but I don't really need it as I don't mind making two clicks to connect to my headset.

I have bluez-libs and bluez-utils 3.36. You have to use passkey-agent with these version though to manage your pins. Alternatively you can use some GUI to authenticate to your headset. Bluez-gnome 0.28 did the job for me once. kdebluetooth-1.0_beta8 should work too.

Thanks a lot erikderzweite. I appreciate your support very much.
I don't understand why, I'm not able to hear anything from my BT Headset even though it connects to my USB Bluetooth dongle without any complication.
KDEBluetooth allowed me to always authenticate the headset, as you told me in your last post.
Once it is connected, I can hear a low noise coming from the built in speaker when I go into the Skype Options->Sound Devices, but I'm not able to hear some sound using skype for calling.
I also tried to do as follows:
Code:
mplayer -ao alsa:device=hw=1.0 /usr/share/sounds/k3b_success1.wav

but nothing happens.

:(

- Check if you have snd-bt-sco module loaded.
- Secondly, check your /etc/bluetooth/hcid.conf. You'll need followings there (not a complete file, only relevant options):
Code:
autoinit yes;
security auto;
pairing multi;
passkey "0000";
# Default link mode
lm accept;

passkey is optional, I don't know if it is actually working but it does no harm (0000 is default pin for my headset)
Restart bluetooth if you needed to make some changes

start "btsco -v XX:XX:XX:XX:XX:XX" from console and tell me the output. In my case it looks like this:
Code:
$ btsco -v XX:XX:XX:XX:XX:XX
btsco v0.41
Device is 1:0
Voice setting: 0x0060
RFCOMM channel 2 connected

Change XX:XX:XX:XX:XX:XX to your headset's mac address, of course.

If you try to play sound then, you should see
Code:
i/o needed: connecting sco...
connected SCO channel
Done setting sco fd


Your mplayer code works for me. Check if Bluetooth SCO is registered as card №1 though:
Code:
$ cat /proc/asound/cards
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfc400000 irq 22
 1 [Headset        ]: Bluetooth SCO - BT Headset   
                      BT Headset 1

Many thanks erikderzweite,
here's my /etc/bluetooth/hcid.conf:
Code:
options {
        autoinit yes;
        security auto;
        pairing multi;
        pin_helper /usr/lib/kdebluetooth/kbluepin
}
device {
        name "BlueZ at %h";
        class 0x100100;
        iscan disable; pscan disable;
        lm accept;
        lp rswitch,hold,sniff,park;
        auth enable;
        encrypt enable;
}

I didn't set passkey because I use the pin_helper which requires me the pin (it happened only once, because I clicked on Always authorize).
Anyway, it associates without any problem.
Now, I switch on my headset.
I can hear a beep (it always happen when it associates to my cell phone) and the kbluemon icon becomes blue. So the headset has been associated, actually I can read the tool tip text saying Connected to Nokia BH-900.
I start btsco.
Code:
btsco -v XX:XX:XX:XX:XX:XX
btsco v0.41
Device is 1:0
Voice setting: 0x0060
                     <--- blank spaces for few seconds...
Can't connect RFCOMM channel: Operation now in progress

Now, once again:
Code:
btsco -v XX:XX:XX:XX:XX:XX
btsco v0.41
Device is 1:0
Voice setting: 0x0060
RFCOMM channel 2 connected

I wonder why, it doesn't work at the first time. :?
If i press some button on the headset...
Code:
recieved AT+CKPD=200
recieved AT+CKPD=200
recieved AT+CKPD=200

It seems all OK now.

Let's now play a sound. Opening another shell, this is what it happens:
Code:
mplayer -ao alsa:device=hw=1.0 /usr/share/sounds/k3b_success1.wav

Maybe the problem is here:

What versions of bluez-libs, bluez-utils and kdebluetooth do you use?

Just a wild guess in case you are using bluez 2: — disable kbluetooth and try making clean pairing — put your headset in pairing mode and issue followings:
Code:
rm /var/lib/bluetooth/ -r
/etc/init.d/bluetooth restart
hcitool cc XX:XX:XX:XX:XX && hcitool auth XX:XX:XX:XX:XX

Your headset should pair.
Then try btsco again (don't start kbluetooth).

I use 3.36 version of bluez, both libs and utils. Version 2.25 worked for me too, IIRC.

I use bluez and bluez-lib 3.36, and kdebluetooth-1.0_beta8.

I tried to do the same steps described before, closing kbluemon but nothing new.

No, it's not the problem, I see the same when I play the wav.

Not an actual problem either, don't know why, but when it connects, it does it properly.

Code:
i/o needed: connecting sco...
 Can't connect SCO audio channel
 : Connection timed out

That is the problem. I fail to see why it is happening though. Had similar behavior in the past when the dongle didn't get proper authorization...

Let us try followings (you'll need 3 terminals) and my /etc/bluetooth/hcid.conf
Code:
options {
        autoinit yes;
        security auto;
        pairing multi;
        passkey "0000";
}
device {
        name "BlueZ (%d)";
        class 0x000100;
        iscan enable; pscan enable;
        lm accept;
        lp rswitch,hold,sniff,park;
}


- Be sure to exit kbluetooth, kbluemon and similar.
- Unplug your dongle
- terminal 1: #rm /var/lib/bluetooth/ -r
- put your headset in pairing mode
- plug the dongle back
- terminal 1: #passkey-agent --default 0000
- terminal 2: $btsco -v 00:0B:2E:70:51:BE
(expected output: terminal1: "Passkey request for device 00:0B:2E:70:51:BE", dongle pairs successfully, terminal2 show normal connection log)
- terminal 3: $mplayer -ao alsa:device=hw=1.0 /usr/share/sounds/k3b_success1.wav
(expected result: you should hear it now)

If that doesn't help, provide the output of hciconfig -a, maybe the dongle doesn't support audio in the first place :)

All went as you wrote. Furthermore, at this time, I could connect at the first attempt using btsco.
All seems ok up to the last but one step.

When I try to listen for a wav or mp3 file, I can't hear anything. Only a low noise can be listened.

This is the output of the hciconfig -a:

You still can't connect to SCO audio channel?

Code:
hci0:   Type: USB
        BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 120:20 SCO MTU: 0:0

Not good: SCO MTU should be more like 64:8... Try setting hciconfig hci0 scomtu 64:8 ACL MTU is 310:10 in my case, can be set with aclmtu option, but unlikely to matter.

Code:
Name: ''

The name is empty? Shouldn't be a problem though as you can pair the dongle

Code:
Manufacturer: Silicon Wave (11)

Cambridge Silicon Radio (10) is known to work particulary well. I haven't seen a Silicon Wave dongle before...

If setting scomtu doesn't solve the problem, you maybe should consider buying a new dongle, sorry :( I use Hama Nano Bluetooth USB Adapter.

It seems to be not possible. After few seconds I get:
Code:
i/o needed: connecting sco...
Can't connect SCO audio channel
: Connection timed out

But once I got the following messages:
Code:
speaker volume: 0 mic volume: 0
i/o needed: connecting sco...
connected SCO channel
Done setting sco fd

Nothing happened. I couldn't be able to listen any audio file.

I tried to set up all necessary and here is the output of hciconfig -a hci0:

I don't know how to set that values persistent. I don't want to manually set up values as it follows:
Code:
hciconfig hci0 aclmtu 310:10
hciconfig hci0 scomtu 64:8
hciconfig hci0 name USB-BT

Me too! That dongle is a gift.

No problem!

Maybe I will buy one as soon as possible! :)

Thanks a lot.

In addition to proposed solution to use btsco as described here: https://forums.gentoo.org/viewtopic-p-5384984.html#5384984
It is possible to use btsco with newer kernels and new HCI USB driver. You just have to edit ebuild accordingly:
Code:
--- btsco-kernel-0.41.ebuild    2008-07-18 02:23:43.000000000 +0200                 
+++ btsco-kernel-0.41-r1.ebuild 2009-01-23 12:36:35.463663192 +0100

That way you will be able to use btsco with new HCI USB in-kernel driver. Just tested it on linux-2.6.28-tunonice-r1, works fine.

Is it still necessary to use the kernel patch in this case?
