I tried playing with privacy, but could not get it to work. But that
was some time ago, and I could have messed it up.

Ok, if bluetoothd does not know I've done this, that would kind of
explain the problem.

I'm trying to run gatt-server, so I'll need to get static address to
work somehow. What is the correct way to set static address, so that
bluetoothd has chance to know about it? Do I need to patch sources for
that?

Privacy does not do exactly what I need, but I'll try. 

Thanks a lot for help,
