[Bluez-users] bluez 3.5 and link_key_request but no pin request and btsco failure

["fabrice régnier" <regnier.fab@free.fr>]

Hi all ;)

It seems i have a prob when pairing with my headset (that used to work). =

In syslog, i have only link_key_request but nothing about pin request.
If we say i'm connected without pin request, i still have a prob with =

btsco (see above).

I'm running debian etch on a 2.6.15

here is my hcid.conf:

FR-PORT:/etc/bluetooth# cat hcid.conf
options {
         autoinit yes;
         security auto;
         pairing multi;
         passkey "0000";
}
device {
         name "%h-%d";
         class 0x3e0100;
         iscan enable; pscan enable;
         lm accept;
         lp rswitch,hold,sniff,park;
}

here is my rfcomm.conf:

FR-PORT:/etc/bluetooth# cat rfcomm.conf
rfcomm0 {
         bind yes;
         device 00:03:89:AB:3D:76;
         channel 1;
         comment "Oreillette";
}


what i've done:

FR-PORT:/etc/bluetooth# /etc/init.d/bluetooth restart

I put my headset in pairing mode then...

at the end:

Does it mean that my headset is correctly connected ?
The worse is later:

Sorry for this long post but i start losing hope ;)

any advice ?
