mini pro has bluetooth problem after pairing?

[wormite]

I updated to the ICS and started to try on the bluetooth on my laptop and the car hands free board player. I didn't try it on GingerBread previously so I don't know if it is the ICS update that is causing this. When pairing with the laptop it prompts about the passcode on both the laptop and the phone, then right after the pairing the laptop sees the phone as offline. However the phone still sees the laptop as online and if I right click the bluetooth icon on the laptop and select receive files, then the phone can send a file to the laptop.

The question is, how come that the laptop keeps on seeing the phone as offline right after being paired up with it?

I'm not sure. Does is show status "online" during file transfers or other activity?

Perhaps it just shows as offline during inactivity. It could also have something to do with battery saving.

After "successful" pairing, the phone will be showing the computer as online while the computer is showing the phone offline. Then if I unpair the phone, and then try to pair the phone with the computer again, the computer shows it as online very shortly. The behavior in this case varies, sometimes the computer can start to install the phone driver, sometimes it reports an error of failing to recognize the driver and demands removing of the phone from the bluetooth list, sometimes it does install the driver and the phone goes back to offline again.

The send file via bluetooth using the windows bluetooth devices icon on the right bottom corner always fails, even if the phone sees the computer as online and authenticated. However, I have successfully sent file to the computer by using the bluetooth "receive a file" function from the right bottom icon.(Although phone is seeing the computer as not connected.)

My description of this can really just be, the phone bluetooth is failing the connection right after it is paired/authenticated somehow.

Hope it helps.
