please take no offense, but this kind of notes are not very helpful. 
this is what i call "linux howto-style" documentation. all it (usually) 
does is provides list of some commands to execute without giving any 
background information. it may work for some users, however, when 
someone's environment is not exactly the same it does not work and 
leaves no clue to what might be going wrong and how to fix it.

personally, i've seen quite a few wiki's/howto's/etc. related to freebsd 
and bluetooth, however none of them gives all the information.

so, it would be very nice if someone wrote a document describing 
bluetooth basics, i.e.

- concept of baseband (physical/radio) link

- concept of logical links, i.e. l2cap and rfcomm

- concept of l2cap psm and rfcomm channel

- what is pairing, how it works exactly and why one needs it

- concept of bluetooth services/profiles

- concept of bluetooth service discovery

thanks,
max
