[Bluez-devel] How 'respond' in BlueZ to a PIN request ?

Hi to all,
if i set my usb dongle in authentication mode
(hciconfig hci0 auth) and connect to my bluetooth phone, 
(hcitool cc BTADDR) the phone ask me for the pin of my pc, 
and after i ve entered correctly, the connection i created.

My question is: how can i control the same thing on my
bluez pc ? If i do the same (hcitool cc BTADDR) to connect
another pc instead of my phone no PIN is requested and
create connection fails! 

I need to know this beacause i need to write a simple program
that listen for l2cap connection on a socket, GIVE THE PIN, and
allows the connection to be estabilished.

Thanks a lot!

Andrea

if you talk about L2CAP then you don't use security mode 3, which is
activated after "hciconfig hci0 auth". You should only do this when you
really know what you are doing. The same applies to "hcitool cc ...",
because this is a testing and should not be used at all.

The L2CAP has options to require authentication and encryption. You
should look at the l2test code for an example.

Marcel
