Shouldn't IOBluetoothHandsFreeDevice take care of this? Or I have to do some other things to get the audio from my iPhone to be heard on my Mac? This is probably a bug in 10.9 . You still need to add a persistent audio device driver (IOBluetoothAddSCOAudioDevice) before you try to establish an HFP connection. IOReturn result = IOBluetoothAddSCOAudioDevice([device getDeviceRef], (CFDictionaryRef)[NSDictionary dictionaryWithObject:@"YES" forKey:@"Autoconfig hidden"]); IOBluetoothAddSCOAudioDevice will become a No-op in future versions.

I know Apple Notification Centre Service takes care of this, but then my app can just be used with devices supporting ANCS. Most of the head units out there does not,. > When my phone is connected to my car stereo, and Im getting a text-message, this message is shown on my stereo. So, how can I use the same protocol for pushing my apps notifications the same way? iOS devices use the Bluetooth Message Access Profile (MAP) to allow Car Kits to display incoming SMS messages. http://support.apple.com/kb/ht3647 My own Phone Amego includes a Mac_OS_X MAP client similar to what might be implemented by a Car Kit. The MAP spec is easily found on-line and specifies two roles: Message Server Equipment (MSE), and Message Client Equipment (MCE). For an iOS App, you would need to interact with the existing MAP MSE and I’m not sure this is possible outside of sending (or simulating) an incoming SMS to the phone.

Re: Low Energy Devices & Serial Ports

There’s also a heart rate sample application that does all of the CoreBluetooth work for you (hopefully it works with the Polar device you have). https://developer.apple.com/library/mac/samplecode/HeartRateMonitor/Introdu… Low Energy stuff doesn’t use the serial port profile that classic does and trying to map it on top might be more trouble than directly accessing the data.

I remember there was also a way to setup such a master/slave pair programmatically but cannot remember how to do or google that.
