Can I set a DeviceClass that is not pre-defined?

[thepurplepig]

I am using BluetoothDevvicePicker, but I want to filter out devices that aren't my device.
My device has a service class of 2900, I can't create a DeviceClass to add to the filter list as it does not correspond to any of the enumerated options.
Is there any way I can create a ClassOfDevice with the value 2900?
Thanks

Never mind, this seems to do it:
ClassOfDevice cod = new ClassOfDevice((DeviceClass)2900, (ServiceClass)(00));

The ClassOfDevice contains the DeviceClass in the bottom 12 bits and the top 4 bits are the ServiceClass. If your raw CoD is 0x2900 this equates to ServiceClass = LimitedDiscoveryMode and DeviceClass = Medical
