Here is what I use in BuddyPop :
IOBluetoothSDPServiceRecord *dialupServiceRecord;
BluetoothRFCOMMChannelID rfcommChannelID;
dialupServiceRecord = [device getServiceRecordForUUID: [
IOBluetoothSDPUUID uuid16:
kBluetoothSDPUUID16ServiceClassDialupNetworking] ];
[dialupServiceRecord getRFCOMMChannelID:&rfcommChannelID];
status = [ device openRFCOMMChannelAsync:&mRFCOMMChannel
withChannelID:rfcommChannelID delegate: self ];
I use kBluetoothSDPUUID16ServiceClassDialupNetworking because I see
AddressBook use this channel (for the phones I tested). Since this is
the same channel as AB, I gracefully free the connection when AB is
launched, and re-establish it when it is quit.
I think this is the better way for application providing the same
features as AB in a different way, like BuddyPop or your product. There
would be conflicts if people install both your product and BuddyPop,
but that's life !
