Hmm... Is there a way to make it 'discoverable'? Anything in user interface?

Sometimes devices use a special trick where device class bits can be used to 
provide information about services. This way remote device can learn about 
services without performing a full blown sdp discovery. So you might want to 
try and play with it.

Yes. Device can be set to non-discoverable mode.
