CC2564MODAEM: CC2564MODEAEM (HFPAG example): problem with the connection establishment to a headset

Part Number: CC2564MODAEM
Other Parts Discussed in Thread: CC2564

Hello TI team,

I have a similar problem as described in

I also use a CC2564MODEAEM with the HFPAG example.

I have two headsets from different suppliers.

The connection to one of them works fine.

The connection to the other one will closed at the same point.

And I do not understand why.  

I use a STM32F4 microcontroller with the CC2564 bluetooth module.

I try to log the HCI interface as you describe in the swpa234.pdf “CapturingBluetoothHostControllerInterface(HCI)Logs”.

For my opinion the connection starts and I can get the "HFRE Call Waiting Notification Activation Indication, ID: 0x0001, Enabled: TRUE." message but after a few seconds the headset close the port.

And I get the message "HFRE Close Port Indication, ID: 0x0001, Status: 0x0001."

Do you have any idea if there is something missing in the communication on the audio gateway side?

I have a command and a HCI log file from the connection establishment.

You can find them in the zip file below.
