Hi,
I'm trying to connect to my Lego Mindstorms NXT using bluez-libs and
bluez-utils 3.7.
I've tried various programs to connect, but I basically just need a
/dev/rfcomm0, but no program seems to be able to use it.
I get the following message even when I have the passkey-agent from utils,
or the gnome bluetooth-applet.
I've heard I should be able to find out if the passkey-agent is registered
by reading the syslog. I use Fedora Core 5, but I don't know where that is -
do I need to set a config file somewhere to tell bluez where to log to?
Thanks,
Jonny

I managed to fix it by removing the entry in
/var/bluetooth/[address]/linkkeys.
Thanks to both of you,
Jonny

actually that is wrong. There will be no request for a new PIN code.
Once a link key has been created, this link key can be used to create a
new link key. However to use this key, you need a successful established
and authenticated connection. This is not the case here.
And this is a security mode 3 connection. Make sure that your own device
in not in security mode 3, because this messes things up no matter what.
My simple guess would be that the link key is no longer valid and the
remote device needs to be put into pairing mode. So you can either do
that or remove the link with RemoveBonding D-Bus method.

Marcel

Hi Jonny!
It seems that your computer have paired with the device before and
stored the link key. So there is no need to call the passkey-agent to
get a new PIN code from the user. You can use
hcitool key device_addr
to change the link key, and this will ask you for a new PIN code.
