iPhone and iPad can't find each other via bluetooth

I have an iPhone 4s and an iPad 2 which should be able to establish a connection via bluetooth. Bluetooth is activated on both devices, and both are scanning for other devices, but none of them shows up on the other one.

If i turn on the personal hotspot on the iPhone, both devices find each other.

Sadly, this is not a solution for me, because I´m writing an app which should establish the connection (using GameKit), so the user must not be forced to activate the personal hotspot before using the app.

So my question is: Is there anything I am missing, to make both iOS devices see each other without using the personal hotspot function?

Any help is appreciated!

Don't know, what are you trying now? – borrrden
the goal is to make the devices visible to each other in iOS, because then it will also work for GameKit (as far as I could test it for now). – a.barth
Only devices that can be paired and are supported show up in the Settings.app, if you use GKSession they will be able to find and connect automatically without having to be paired by the user... – jjv360
@jjv360 strangely, that wasn´t the case. Now everything works fine, but i´ll have to test if the problem reoccurs, as soon as two devices, that didn´t know each other before, try to connect. – a.barth

iPad 2 is NOT supporting BLE 4.0 and it has different hardware module for bluetooth. Maybe that's the main problem.

Make sure the session id in both is the same, or they will not find each other.

- (GKSession *)peerPickerController:(GKPeerPickerController *)picker sessionForConnectionType:    (GKPeerPickerConnectionType)type{
GKSession* session = [[GKSession alloc] initWithSessionID:@"com.cilk.id" displayName:nil sessionMode:GKSessionModePeer];
return [session autorelease];

}
