DeviceAdapter not raising some events -- HTC Tatoo Can't find any devices

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Referenced AndroidBluetoothAPI_0.3.jar in build paths as external
2.Checked if localBluetoothDevice.isEnabled()
3.Called localBluetoothDevice.scan();

What is the expected output? What do you see instead?
scanCompleted should return non-zero value; I have a moto headset that
works with the phone turned on next to it.
Only scanCompleted is called; scanStarted() is never called;

What version of the product are you using? On what operating system?
AndroidBluetoothAPI_0.3.jar HTC tatoo 1.6

Hi,

I have same problems and came to the conclusion that the Tattoo does not 
support bluetooth to such extend which can be used by the unofficial API or 
backport. I also tried the "Bluetooth File Transfer for Android!" from 
http://www.medieval.it which explicitely states when starting the App that the 
Tattoo does not work.
