I have done exactly the same, it just was not intuitive and differs from 
NetBSD as I understood it. It was probably the first time when I needed 
to know my adapter BDADDR.

It does not happens when connection is alive, only when connection 
establishes. So may be there some kind of timeout can be tuned, or 
device can be forcefully woken up in some other way?

One more minor fact. Unlike rfcomm_pppd I haven't found an option to run 
btpand in foreground to track connection status.
