Is it possible to know if an iPhone is paired with the hands free system in a car using the CoreBluetooth or the EAAccessoryManager? If not, is there another way to do it?

If the iPhone considers the car an accessory you can get the connected accessories by calling:

[[EAAccessoryManager sharedAccessoryManager] connectedAccessories];

This will return an array of EAAccessory objects which you can then query to get certain information like the name: accessory.name.

I don't know for certain of this will work with cars having never tried it myself (I have used it with other accessories), so I would suggest that you create a test app that logs the connected accessories to the screen on demand and test it yourself.

Here's the documentation for EAAccessoryManager and EAAccessory.

  • Thanks for your answer. I already tested that and the car don't appear in the connected accessories. I think the EAAccessoryManager only shows accessories under the MFI program. Is there any way to detect accessories that don´t follow the MFI program? – user3849954 Nov 28 '14 at 17:00
  • As far as I'm aware the only objective-c frameworks for bluetooth are CoreBluetooth and ExternalAccessory. That's not to say there isn't a third party one that will work with non MFI accessories. Other than that you could take a look at the IOKit or some C libraries. You have to be careful as some of these frameworks are private and your app will be rejected by apple if you link them in your project. – Rob Sanders Nov 28 '14 at 17:41
