 hi all

 at first I am thinking about the SCO routing= problem, so run

[root@root sbin]$bccmd psset -s default 0x1ab 0
= [root@root sbin]$hciconfig hci0 revision
hci0:   Type: UART        BD Address: 00:06:6E:05:05:05 A= CL MTU: 310:10 SCO MTU: 64:8
        = Unified 21e
        Chip version: Blu= eCore4-ROM
        Max key size: 128 = bit
        SCO mapping:  HCI
 
here we can see the SCO is mapping to HCI, after this= , i try hstest

[root@root bin]$hstest play 1.wav 00:0D:3C:E8:1A:AC 2= &
Voice setting: 0x0060
RFCOMM channel connected
SCO audio ch= annel connected (handle 45, mtu 64)
AT+VGS=3D11

there is still no= sound output from headset, that's why?
who can help out , thanks in adv= ance!

Tony

 hi everyone

 I'= m experimenting with the i-tech BlueBAND headset with bluez, this headset s= upport HS,HF,A2DP and AVRCP profile, But for me, I only want to test the MO= NO for telephoning. it doesnt work well now.

toolchain: kernel 2.6.1= 0, bluez-libs/utils-3.12, CSR BC4 UART interface
(the version of the too= lchain is old, but I must work on that)

I will definitely test HeadS= et profile, so btsco/snd-bt-sco are not included. and I use the hstest in b= luez-utils. hcid,hciattach,sdpd are always work well.

when send audi= o to headset:

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

Here the headset bee= ps (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
