security auto;

No, there was no change on my 6310i display.
But on my laptop display I got a dialog asking for the PIN.
Where do I get this mysterious PIN?
I tried making one up. Then it worked!

Is this PIN stored somewhere? I see a file

/etc/bluetooth/pin

but it doesn't contain the PIN that I typed into the laptop dialog and
the phone dialog.

No, the PIN is only needed for Pairing bluetooth devices. The
/etc/bluetooth/pin specifies a lasting key you take for every
connection. It is taken instead of the key you insert in the dialog-box
for incoming connections.
The PIN you insert is stored nowhere, but the devices generate a link-key
from the pin and other data, this stored in the /etc/bluetooth/link_key.
