How to connect to bluetoothbee device using j2me? - java-me

Question

I developed a simple bluetooth connection application in j2me.
I try it on emulator, both server and client can found each other, but when I deploy the application to blackberry mobile phone and connect to a bluetoothbee device it says service search no records.
What could it be possibly wrong? is it j2me can not find a service in bluetoothbee?
The j2me itself succeed to found the bluetoothbee device, but why it can not find the service?
My code is below. What I don't understand is the UUID? how to set UUID for unknown source? since I didn't know the UUID for the bluetoothbee device.
