 hi everyone

 I'm experimenting with the i-tech BlueBAND= headset with bluez, this headset support HS,HF,A2DP and AVRCP profile, But= for me, I only want to test the MONO for telephoning. it doesnt work well = now.

toolchain: kernel 2.6.10, bluez-libs/utils-3.12, CSR BC4 UART i= nterface
(the version of the toolchain is old, but I must work on that)<= br>
I will definitely test HeadSet profile, so btsco/snd-bt-sco are not = included. and I use the hstest in bluez-utils. hcid,hciattach,sdpd are alwa= ys work well.

when send audio to headset:

[root@root bin]$hst= est play 1.wav 00:0D:3C:E8:1A:AC 2 &
Voice setting: 0x0060
RFCOMM= channel connected
SCO audio channel connected (handle 45, mtu 64)
AT= +VGS=3D11
AT+CKPD=3D200
AT+CKPD=3D200
AT+CKPD=3D200
AT+VGS=3D1= 2
AT+VGS=3D11
AT+VGS=3D10
AT+VGS=3D11
AT+VGS=3D12
AT+CKPD=3D= 200

Here the headset beeps (it does that everytime a connection = is initiated) =20 and I can hear only some noise through it. By pressing one of= the buttons on the headset I even see the AT-comands which are submitt= eted via the rfcomm =20 channel. But no audio. A hcidump during the connection procedure s= hows just a normal looking =20 bunch of hci and acl commands and events, but no sco packets = whatsoever.

here the SCO is connected
[root@root bin]$hcitool con=
Connections:
        < SCO 00:= 0D:3C:E8:1A:AC handle 45 state 1 lm SLAVE
     = ;   < ACL 00:0D:3C:E8:1A:AC handle 43 state 1 lm MASTER ENCRYP= T 

Am I doing something wrong or missing=
 a step? 


Thanks for your help and=
 best regards
Tony
