Eduardo Velloso has implemented a beta driver for the Bluetooth module.  The driver makes the Bluetooth module discoverable from Windows Devices & Printers and other Bluetooth devices.  The source code can be found at https://gadgeteerbluetooth.codeplex.com/ .  The solution includes the driver implementation code and a test project using .NET Gadgeteer.  For more information, see Eduardo Velloso.

Eduardo has also created a test scenario that demonstrates communication between two Bluetooth devices built on .NET Gadgeteer.  For details, see http://eduardovelloso.com/2012/04/03/bluetooth-communication-with-net-gadgeteer/ .
