Is there any way to connect GKSession only through Bluetooth?

Can we force GKSession connection only through Bluetooth?..I know its is possible through GKPeerPickerController , but i am not interested in GKPeerPickerController interface..I need to connect my application in two device only in Bluetooth rechability zone..but what happened is if WiFi is enabled , the device will still keep connection beyond the limit of Bluetooth.and for some other reasons i cant switch off my WiFi in device..any idea about this will be app开发者_StackOverflow中文版reciated ..

There is no proper way for forcing GKSession to connect only through Bluetooth.the only way i found is keep server/client device WiFi off.So that it will connect via Bluetooth.Thank you,
