Hi,

I´m new to the list, my names nick and I´m from Bielefeld, Germany.

I´m still experimenting with my usb-dongle from acer

lsusb: Bus 003 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd
Bluetooth Dongle

and try to get it work with my logitech bluetooth headset via btsco
and the snd-bt-sco module.

Versions:

kernel: 2.6.9-gentoo-r6
bluez-framework: gentoo-unstable
btsco: btsco-cvs 28.11

everything works fine, bluetooth started alsasound started /dev/dsp1
is there, i can connect to my headset via btsco and it gives me
something likes this:

Device is 1:0
Voice setting: 0x0060
RFCOMM channel 1 connected
recieved AT+CKPD=200
opened hwdep
connected SCO channel
Setting sco fd
Done setting sco fd
recieved AT+VGS=11
Sending up speaker change 11
recieved AT+VGS=12
Sending up speaker change 12
recieved AT+VGS=13
Sending up speaker change 13

so, i can change the volume with the buttons on the headset, also i
hear some "noise" after connecting to the SCO channel with the
,multifunktional button on the headset.

my problem is:

i can´t get sound over the device. something dirty like:

cat foobar.file > /dev/dsp1

does nothing, until i cancel it with ctrl+c, also xmms (when
configured for hw:1 alsa with BT) just waits and does nothing.

my normal soundcard is a:

0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB AC'97
Audio (rev 03) snd-i8x0

any suggestions?

~ ,nick

PS: obex file transfer and push to my t68i works, so the sdp-server is
running.

check with "hciconfig hci0 revision" (as root) for the setting of the
SCO routing. I think it is set to PCM.

you were right:

(0:1)root@Muramasa:~$ hciconfig hci0 revision
hci0:   Type: USB
~        BD Address: 00:60:57:02:95:FE ACL MTU: 192:8  SCO MTU: 64:8
~        HCI 12.7
~        Chip version: BlueCore01b
~        SCO mapping:  PCM

so, is that the way it should be?

to use your dongle with a headset it must be set to HCI. This value is
stored in the PS keys and it is changeable, but there exists no free
tool for this job.

Marcel

well there is one tool:
get the csr reset utility, it contains source code to also alter the hci=20
mapping (which I used on my vaio):

excellent it works. that was easy. i think i´ll take a look at the
source code, to know what the tool is doing. ;)

is this a vaio specific thing, got a vaio v505cp myself.

no,
these extensions are csr-specific (but they are well documented) -- they=20
use extended
hci commands to access the configuration registers of the bt dongle.
