Bluetooth Connection with Hands Free

[temp123]

I wrote tiny bluetooth Audio gateway for audio transfer to the BT hads free device.

Proble I am facing is in receiving AT commands.

After making BT radio ON when my AG try to connect with BTHF and gets connected and negotiated with proper At commends and responses successfully but after that my AG didn't receive any AT commands for call operating like ATA,CHUP or BLDN and none. When my AG sends AT commands like RING it operates correctly and play ring but my AG didn't receive any At commands from HF.


This problem happens only when I break active connection by making BT radio OFF. It doesn't create any problem if I break active connection by making BTHF OFF. Why my AG didn't get any AT commands from BTHF?????

Is there anything to say to BT stack or BTHF???

Any registry to cahnge?
When I make BTHF off and try to make connection after makinf ON, it works fine but not working when BT radio is made OFF and then ON, it gets negotiated correctly but after that not responding well and At commands are not received.

It would help if you would post your AG code for debug.
