You can not connect to audio service (handsfree in your case) with using simple RFCOMM connection. The device waiting for SCO connection and it's waiting for specified AT commands sequence. As soon as device does not receive AT command it drops connection. You should know, that this type of connection will establish only RFCOMM (control channel) link and will not allow you to send (and receive) any audio data. You have to establish SCO link to send audio data. Unfortunatly such feature was partialy implemented in BTF and is implemented in WCL (but is not available for public usage yet). Also you should know, that it is possible with using Toshiba, BlueSoleil or WidComm drivers (each one has own limitations). It is impossible with using MS bluetooth drivers.

OK

2 months ago, I got commands sequences to establish the connection with send AT commands

well, I can hold the comunication between hands free and bluetooth dongle

now How streaming audio or establish SCO connection???

Use BFBluetoothAudio and standard windows media functions.

[DragonDBA]

BFBluetoothAudio?

How do get it??? and any example?

  please help me

Bluetooth Framework included such component. Unfortunatly Bluetooth Framework is not supported now. All I can do is just recomend to upgrade to the latest version of WCL. WCL will include audio support in first three months of year 2010.

Mike,

has this been implemented in the library now? I too have a dependency on the audio channel (SCO) for hands free. Any news would be greatly appreciated. Thank you.

[Mike Petrichenko]

WCL does not include such component and there is no timeline for it.
