hey guys I have lots of past experience dealing with bluetooth stuff and just recently started to heavily test some N900 programs that use bluetooth.

microsoft/broadcom bluetooth stack sucks for advanced compatability its really only good for super simple stuff.

Find a external bluetooth adapter that uses the toshiba stack or best yet bleusoleil for much better compatability.

Bluesoleil also works with many many other bluetooth devices even if its not the default stack. All of my laptops have used broadcom stuff stock but bluesoleil worked with them all.

Visit there site and download the trial to see if it works for you.
