[Bluez-users] SCO Connection

[sjok1 <sjok1@student.cs.ucc.ie>]

Hi,

I'm writing an application that emulates a BT Headset and I'm using a Siemens 
S55 and a Sitecom USB BT Adapter.  What I'm doing is the following:
Send a dial command to the phone to dial a number
Send an AT+CKPD=200 to the phone to request an audio link
Create a socket to listen for the SCO conncetion
Accept the connection when it arrives.

My problem is that after I accept the SCO connection no data is transmitted 
along the connection.  The phone recognises that a "headset" is in use, but if 
I try to read from the connection I just get -1 returned as the num of bytes 
read.

I checked my hciconfig revision and it shows that the SCO mapping is set to 
HCI.

Do I need to acknowledge the connection after I accept it?  Is the phone 
waiting for some "ready to receive" message or something?


Thanks.

Steven
