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

Hi
Are you using a minikit? What is the version of STLC2500 chip you are using?
In case you are using minikit along with motherboard you have to enable the
codec. Otherwise you will not hear any sound.

Regards,
Sumeet

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!!
