Issue 94 in bluecove: retrieveDevices of DiscovereyAgent always returns null

New issue 94 by evoid.de: retrieveDevices of DiscovereyAgent always returns
null
http://code.google.com/p/bluecove/issues/detail?id=94

To reproduce the problem, use exactly the following code on Ubuntu Linux
9.10 while having at least one bluetooth device paired with the system the
code is running on:

public class Test
{
public static void main( String[] args ) throws IOException
{
RemoteDevices[] devices =
LocalDevice.getLocalDevice().getDiscoveryAgent().retrieveDevices(
DiscoveryAgent.PREKNOWN );
System.our.println( devices );
}
}

The expected output will be a list that contains your paired devices. But
what I get is always 'null', no metter whether the paired devices are
running (have bluetooth turned on) or not.

I'm using the latest BlueCove release, namely version 2.1.0, including the
bluecove-gpl module. I don't know where to look up the build number this
tool is requesting me for. I'm not sure but I think it's all 32 bit here.

Thanks in advance

How is this supposed to help me? I think you did not understand what my
problem is. I
don't want to perform an inquiry for new devices, I just want to get a list
of all
the devices that are already paired with my system. Or do you want to say
that I must
perform an inquiry first anyway?
