Re: [Bluez-users] How to enable eSCO in linux 2.6.18?

["dong yan" <semiydsemiyd@gmail.com>]

Hi Sumeet VERMA:

   Thanks a lot!
   As a matter of fact , im using ST's bluetooth chip STLC2500. This
chip can't establish SCO connections under linux 2.6.18, so i had to
try eSCO connection.....that's why i want this esco patch.  i applied
your patch and eSCO seems to be connected. But still there's no sound
coming out of my bluetooth headset...
When i tried to disconnect the esco channel , hcid reports an
error..... Please refer to the details in this log:
(I use 'hstest' from bluez-utils to test the SCO/eSCO.)

 $ hstest play /tmp1/1.wav 00:0D:3C:EB:53:F0 1
Voice setting: 0x0060
hcid[173]: link_key_request (sba=00:80:E1:00:AB:BA, dba=00:0D:3C:EB:53:F0)
hcid[173]: link_key_request (sba=00:80:E1:00:AB:BA, dba=00:0D:3C:EB:53:F0)
RFCOMM channel connected
KERNEL:sco_connect(): type=2,eSCO

SCO audio channel connected (handle 8, mtu 60)
hcid[173]: link_key_request (sba=00:80:E1:00:AB:BA, dba=00:0D:3C:EB:53:F0)


/ $
/ $ hcid[173]: Disconnection failed: 0x0c

At the sametime , if i use another  USB bluetooth module instead of
STLC2500 , i can hear the music with my bluetooth headset after
established SCO connection.

Please, let me know if you have any other suggestions,thanks!!
