iPhone - detect nearby bluetooth devices

Is it possible to find bluetooth-enabled devices near my iphone from an app? I am able to do it using the GameKit framework, but that开发者_开发百科 has a limitation that both devices must have my app installed and running.

Is there a way to detect iPhone devices nearby using bluetooth even if they are not running the same app?

Thanks.

Not really. Apple doesn't give the iPhone much Bluetooth interactivity, except for the wireless headphones and what you can do with GK.
