[Bluez-users] Pairing problems(?)

[Riku Voipio]

Hi,

I'm having problems pairin and hci_usb device and siemens s55 mobile
phone..  Everything seems to work fine, the mobile asks for pin, but
the actual connections time out.

 nchip@wombat:~$ hcitool scan
 Scanning ...
	00:01:E3:xx:xx:xx       Satu87

 nchip@wombat:~$ sdptool search --bdaddr 00:01:E3:xx:xx:xx DUN
 Failed to connect to SDP server on 00:01:E3:xx:xx:xx: Connection timed out

Thats when the phone asks for pin, and I enter the same one as in the
givepin script I wrote.

After the connection ends, the phone asks if it should add womba-0 to
known devices. even atfer adding to known devices, connections fail.
Trying to connect or send stuff from phone to bluez causes just an
internal bluetooth error.

I tried with and without auth/encrypt. Can anyone hint with me what I am
doing wrong?

rfcomm fails too:

  $ rfcomm
  rfcomm0: 00:01:E3:xx:xx:xx channel 1 clean
  $ rfcomm connect 0
  Can't connect RFCOMM socket: Resource temporarily unavailable

hcid.conf:

options {
        autoinit yes;
        security auto;
        pairing multi;
        pin_helper /etc/bluetooth/givepin;
}
device {
        name "%h-%d";
        class 0x100;
        iscan enable; pscan enable;
        lm accept;
        lp hold,sniff,park;
        auth enable;
        encrypt enable;
}

givepin:

#!/bin/sh
echo "PIN:1234"

this is security mode 3. Don't do it unless you really want it and knows
what this implies.

Regards

Marcel
