Paging a Bluetooth Device

I'm interested in developing a Bluetooth proximity detector, similar
to the BluePhoneElite application, but I haven't been able to figure
out how to go about doing this.
As described in Apple's documentation, "Bluetooth Device Access
Guide: General Design Considerations"[1], I understand that devices
have two discovery modes: "inquiry" and "paging"--or as describes it,
"discoverable" and "connectable" modes.
I also understand, from Apple's documentation that the
IOBluetoothDeviceInquiry class should not be used unless the
application cannot use the IOBluetoothUI class.
So, I want to detect the proximity of a device using the paging, or
connectable mode, and as far as I can tell, using the IOBluetoothUI
class should be fine.
In all of Apple's documentation the only places that I can find
"paging" mentioned is in the document mentioned, and in the
IOBluetoothDevice (not IOBluetoothDeviceInquiry) class documentation.
I've also looked at the example application that came as part of the
XCode install, but it uses the IOBluetoothDeviceInquiry class (that I
understand should only be used with good reason), but still only
discovers devices, but does not page a specific device. Searching
Google has not produced any results either.
Could somebody point me to the class/methods that should be used, or
point me in the direction of the information that I am looking for?
Thanks,
Denver Timothy
