AS over BT
Delete your pc from bonded devices on your xda II if you have it bonded
Here is how I got my bluetooth to activesync with pc. Go into ActiveSync on pc and select File-> connection settings.
Make sure that "Allow serial cable or infrared...." is checked and you have put the COM port as the BT serial port.
On your xda, turn off Bluetooth and then turn it back on.
Go to Settings->System and select Bluetooth settings
Click on the start button to start BT Activesync. You will get a message that you need to set up a device that supports BT AS, XDA will search for devices and find your pc. After bonding pc, you will get a message stating that ActiveSync BT is now setup.
Open AS and select Tools -> Connect via BT (or something), and your pc will prompt you for authorisation.
*If it all works like mine then it will connect ok but the connection will drop out as soon as you try to do anything worth while like surfing the internet over BT or syncing AvantGo* :cry:
