[Bluez-users] Thinkpad X31 @ fedora core 2, trying to connect to Nokia 6380i

[David Wuertele]

I boot my thinkpad, and the bluetooth chip is recognized.  My phone
has bluetooth turned on.  I see my phone when I scan, but I can't seem
to connect with it:

Is there something else I should be doing?

Seems that your PIN exchange doesn't work. What is your "security"
setting in hcid.conf? Does appear a pin windows on the mobile display?

 security auto;

Nicholas> Does appear a pin windows on the mobile display?

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.
