[Bluez-users] pairing with headset

[Bluez-users] pairing with headset

[-- Attachment #1: Type: text/plain, Size: 2298 bytes --]

Hi all,

I am using a 2.6.8.1 kernel and successfully communicate with my
Nokia 6230. Today, I got a Jabra BT 250 headset, which also works
fine.

However, I cannot make bluez see it. What's more, if I pair phone
and headset (which also works), then `hcitool scan` does not find
the phone anymore. I have to delete the pairing between the headset
and the phone to be able to communicate with the phone again.

What's going on? Can the phone only pair with one other device? Or
is the problem elsewhere?

Also, I can't figure out how to pair the computer with the headset
(assuming that phone and headset are not paired). I set the voice
type to 0x0040 (not sure why, but I saw it on the Internet; it also
does not work with 0x0060, the default) and I added Audio and
Telephony to the dongle's classes; I even added the HF SDP service.
But when I execute `hcitool scan`, only the phone shows up.

Here is hciconfig -a hci:

Thanks for any tips. I am a complete bluetooth newbie.

[Bluez-users] suse9.1personal and bluetooth modprobe

[Massimiliano Cuccia]

Hi all,
I'm new to linux and to bluetooth
and I installed the suse 9.1 personal distro.

the command
modprobe -l | grep bluez
does not report nothing

so I think that there isn't any bluetooth support

but the command 
modprobe -l | grep bluetooth
report a lot of voices
and from the console (if I remember) I can start bt,
so my phone (a Nokia 6600) can see my pc

this mean that there is something ... but what?
if I try hciconfig or hciid or hciemu the system
doesn't recognize the command

have I to install the bluez rpm modules?
or I'm ready to use and develop with bt? (i think no)

thanks

With my Motorola v710 and an ericsson h60(?) headset, I have to *turn 
off* the headset before I can connect the computer to the headset. You 
don't have to go through the pain of "re" pairing that way. Even when 
the headset is on but not being used to talk, it seems to have some kind 
of 'weak' connection there.

we're experimenting with audio at 
http://sourceforge.net/projects/bluetooth-alsa/

i will update the cvs sources. currently, you'll have to stick with 
0x0060 (the default). currently, sound is jittery because it uses the 
headset connection to pace the output (it should be tied to a clock instead)

I have Jabra BT250 too.

When you want to pair your Jabra in Bluez, you must set PIN to 0000, which
is Jabras default.
You must hold headset button for about 7 seconds, when blue LED on Jabra goes
permanently ON. Now is headset in pairing mode, and you will see it in
hcitool scan. Jabra BT250 is visible only in pairing mode. Probably due to
security reasons.

This headset can be paired only with one device.
Do you have some other experience?

Other problem is, that I don't know if there are some working bluez sound 
driver. I doesn't test it.

Oh, okay; now I got it working.

> This headset can be paired only with one device.

That's really annoying.

No, but I will let you know.

It is being worked on.
