[Bluez-users] pairing plantronics M3000 with my laptop

[Bluez-users] pairing plantronics M3000 with my laptop

[Laurent Lesage]

Hi all,

I finally got a plantronics M3000 and a bluetooth dongle trendnet TBW-102UB.
I'm using Debian Sarge, up to date, with bluez-utils 2.15, hcidump 1.17, 
kernel 2.6.8.2, debian patch for 2.6 kernel of 28th of march 2005.
First trial, dongle seems OK.
laptop:/etc/bluetooth# hciconfig -a
hci0:   Type: USB
        BD Address: 00:E0:98:FD:9A:BD ACL MTU: 192:8 SCO MTU: 64:8

        Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3
        Link policy: RSWITCH HOLD SNIFF PARK
        Link mode: SLAVE ACCEPT
        Name: 'laptop-0'
        Class: 0x3e0100

        HCI Ver: 1.1 (0x1) HCI Rev: 0x20d LMP Ver: 1.1 (0x1) LMP Subver: 
0x20d
        Manufacturer: Cambridge Silicon Radio (10)

for the M3000, I tried :
laptop:/etc/bluetooth# hcitool scan
Scanning ...
        00:03:89:4C:2D:C7       M3000 by Plantronics

And one of the very first times, I got info from the M3000 with hcitool 
info. "bluez-pin" asked me for the pin (0000) and got the info. After 
that, I used the headset under windows XP, with skype : it worked great 
as headset : clear sound, mic OK. Then back to Linux, and no way to get 
'hcitool info' again.

laptop:/etc/bluetooth# hcitool cc 00:03:89:4C:2D:C7
Can't create connection: Input/output error

I tried in pairing mode but always the same error. this is hcidump 
during "info", headset  in pairing mode or not :

laptop:/home/lesage# hcidump
HCI sniffer - Bluetooth packet analyzer ver 1.17
device: hci0 snap_len: 1028 filter: 0xffffffff
< HCI Command: Create Connection (0x01|0x0005) plen 13

< HCI Command: Link Key Request Reply (0x01|0x000b) plen 22
 > HCI Event: Command Complete (0x0e) plen 10
 > HCI Event: Connect Complete (0x03) plen 11

Finally, I don't understand why it worked the first time, and no more 
now. When it worked, I didn't have to give the PIN once given, to get 
the 'info" again. I suppose this is because the pairing was succesful?? 
How can I verify?

before I go further with 'blue-alsa' and so on, I suppose I have to be 
able to pair the device?

thanks for any link or information,

Laurent Lesage

I would try removing /etc/bluetooth/link_key so the pairing will be reset.

Now, I tried the commands in "hcitool" to create connection and get=20
parameters for the link and the headset. My question : is there a link=20
where you can find more explanation about the result of the commands=20
(what do the values of rssi, lq -link quality-, ... mean? I see the=20
values changing on my screen when I move the headset but I don't know=20
their meaning)

Another question : does the class of the device (you define in=20
/etc/bluetooth/hcid.conf) mean exactly? Does it mean that the dongle is=20
not able to use other device that the one you define with that value or=20
does it mean you *don't want* to use other devices than the ones you=20
define with that value?

thanks for your attention

Hi again...

well, now it seems to work, but I have no sound : it is like the voice=20
packet are not sent to the headset.

1) info about the headset

Using Debian Sarge, with a patch for bluez from march 2005. Got btsco=20
form cvs. Compiled without error. Seems running ok. When using XMMS, I=20
see a second audio device "bluetooth headset", I see it with alsa and=20
with OSS output plugin. If I try to play a song with XMMS, I hear a=20
"beep" indicating the activation of the SCO channel. I can see it with=20
"btsco -v", verbose mode. I also can adjust the volume of my headset :=20
it's echoed on the output of btsco. On the other side, if I use the oss=20
mixer, I hear a small beep in the headset and see that the volume is=20
changed accordingly to the mixer on the computer. Same for microphone.

So (I'm BT newbie...), the "signalling" seems to work perfect *BUT* no=20
voice packet are sent. HCIdump shows the "signalling packets" but after=20
that, no other packet. with XMMS, if I "play", the song remains still=20
(time stops). Just the beep in my ear to say that the channel is opened=20
(I hear the same under WinXP when I accept to "connect" the headset,=20
pushing on the "answer" button of the headset), and another beep when I=20
stop the song and thus, "disconnect" the SCO channel (again, I see all=20
that with btsco -v and hcidump).

When I will get it , I will resume the whole thing for configs like=20
mine. Help me get the sound work :-(

thanks

Laurent

Re: [Bluez-users] pairing plantronics M3000 with my laptop

[Brad Midgley]

Hi

I suspect a volume problem (try using a soft mixer on your computer and 
try volume controls on the headset)

or sco routing; as root run
  hciconfig hci0 revision
and see if sco is routed to hci as it should be

It's possible that Marcel's new pskey program can reroute sco but I 
haven't tried that.

Re: [Bluez-users] pairing plantronics M3000 with my laptop SOLVED

[Laurent Lesage]

Hi Brad,

In fact, it works.... something to do with reboot... A service to=20
restart??? I just restarted the computer, after a small reboot with XP=20
to use the headset for Skype :-(. Just "modeprobed" snd_bt_sco and=20
emu10k1 and ... the sound was here! I just use /dev/dsp1. XMMS works=20
fine (in mono). just a small (half a second you said?) delay when I use=20
the volume control on xmms. I also used my IAX client, to record=20
parameters for voicemail box : no problem (in fact, that's the only=20
recorder I used on Linux). Used with skype : first "echotest" trial gave=20
horrible recording. Second trial ok (??). After that, ok.

So, I will redo all the trip on another computer and try to describe all=20
the steps for a config like mine. Finally, as often, the job made  by=20
the Debian team is really great. Every tool is easily installed and,=20
thank to the job of  bluez, blue-alsa, it works well.

I don't see if alsa is necessary, because I installed alsa afterwards=20
and continue using OSS in the sound applications. But I don't know if it=20
is integrated in the kernel. As the debian packages are available=20
separately, I suppose it is not, but I'm not sure.

I will try later the project with bluetooth channel and asterisk.

see you soon

Re: [Bluez-users] pairing plantronics M3000 with my laptop SOLVED (bis)

[Laurent Lesage]

Well, just to add that sometime, the sound disappear when using skype or=20
IAX client. I must stop the call and redo it to get the sound back.=20
Maybe another application picked up the route? (grip and XMMS where=20
present at the same time).
