My application (Phone Amego) connects with a Bluetooth phone using the
Handsfree Profile for the purpose of CallerID and dialing. I've
noticed some phones establish an audio connection with the Mac by
default such that the speaker and microphone on the phone itself is
disabled.
I'm trying to figure out how to disable this audio connection.
Can anyone point me in the right direction?
Thanks,
- Peter
P.S. I've spent a little time searching, but so far am finding dead
ends.
- The Official Handsfree Profile spec does a nice hand wave by saying
some external or user initiated event causes the audio connection to
release.
- The Headset Profile spec shows a picture of sending "AT+CKPD" to
establish an SCO connection or release it, but there are no other
details.
- Other documents hint at advertising an audio gateway profile and
accepting an SCO connection. I found IOBluetoothRemoveSCOAudioDevice
(), but this function has been deprecated and is no longer available
as of 10.6 .
