Hello,

Is it possible to have a rfcomm connection with a bluetooth headset on top of which to start/stop SCO connection ?

Usage scenario: a RFCOMM connection has to be maintained to a bluetooth headset to get button press events, but in the same time, SCO is activated to play/record sounds using the headset.

So far, I could make a RFCOMM connection to capture button press events, but I couldn't start SCO in any way. SCO seems connected to a system audio device which connects/disconnects the headset when needed. I couldn't find any method to control SCO from API.

How can I solve the problem in the above given scenario ?

Do I need to develop my own SCO layer over RFCOMM and create a new audio device driver ? Any pointers to do such a thing ? I've tried IOBluetoothAddSCOAudioDevice, but it's a deprecated function and the only thing it does, is to create the associated audio device, if such a device is not already present. My code is the following:

void* keys[1];

keys[0]=[[NSString alloc] initWithCString:"IOAudioControls"];

void* values[1];

id array=[[NSMutableArray alloc] init];

values[0]=array;

CFDictionaryRef dictionary=CFDictionaryCreate(NULL,keys,values,1, &kCFTypeDictionaryKeyCallBacks,&kCFTypeDictionaryValueCallBacks);

IOReturn res=IOBluetoothAddSCOAudioDevice(m_headset,dictionary);

The operation was successful in the case when the audio device didn't exist. In the case when the device existed (created using bluetooth interface in the OS), the function returned a general error.
