Bluetooth: Unable to detect devices on Nokia Phones

Question

Hi
The following piece of code for bluetooth detection and connection works(able to detect and connect to other bluetooth devices) on my Sony Ericsson K750i Phone but not on a Nokia N81(unable to detect any bluetooth devices).
Can someone please help, i need this thing urgently.
Many thanks

I have K610i with satellite pro a300-1nt, after it came from service, i can connect to my desktop via bluetooth, but if i try to connect to k610i it says unable to detect remote device. ideas? it says that just on those devices which were registered before (ie, my, sisters phone)
(EDIT: i cant use cellphone as remote controll, i can only send files to computer.)
i've tried diagnostics, first passed 2nd failed. i use toshiba's bt stack v7.10.12(T).
thanx in andvance
