You don't after the PIN transaction has completed successfully the
stacks handle the link generation. Links are stored under
/var/lib/bluetooth/<hci address>/linkkeys take into account that if you
switch from windows into linux, or if you plug your bluetooth dongle to
another pc, you will need to remove the linkkey from the file or it will
never work. It's like when RSA keys changes for a server.

Exactly.

rfcomm as a tool isn't supported any more, rfcomm as technology is and
is the base for most of the bluetooth services. The new way is using the
dbus serial service. Which will also generate the rfcomm node, in a more
simple way, but if your distro is not well configured, it can be a
headhacke to get it to work.

You WANT to get deep into bluez dbus api, not into the old hci lib api ;).

Where? I don't think this list can take attached files.
