Unhappy Samsung SGH-D840 won't Bluetooth pair to server?

I'm quite new to using bluetooth in Linux and need some help.

My problem is, I can send image files to my old phones (Sony, Nokia) using ussp-push from the CLI without being prompted for a pin, but not my Samsung SGH-D840. It wants to pair with a pin before the copy can take place. I'm not able to pair even after following all the advice of others with a similar problem. Because I'm scripting this, I want to be able to do this from the CLI rather than from an X desktop.

I've had a good look around the phone config and it seems its not possible to turn this pairing request off. It does have a 'secure mode' option, but it doesn't actually change anything if its off or not, even after a phone power cycle.

OK, so this is what I've doing...

# sdptool search --bdaddr 00:11:12:13:14:15 OPUSH
Searching for OPUSH on 00:11:12:13:14:15 ...
Service Name: OPP
Service RecHandle: 0x10007
Service Class ID List:
"OBEX Object Push" (0x1105)
Protocol Descriptor List:
"L2CAP" (0x0100)
"RFCOMM" (0x0003)
Channel: 3
"OBEX" (0x0008)
Profile Descriptor List:
"OBEX Object Push" (0x1105)
Version: 0x0100

So the Samsung's OBEX channel is 3.

I run the following ussp-push command to push the file, shortly after running it the Samsung asks for a pin to pair with the PC. I enter 0000 and nothing else happens apart from the phone returning 'Invalid pin. Unable to connect'.

# ussp-push -dev 0 --debug 00:11:12:13:14:15@3 image.gif image.gif

pushing file ../data/test1.gif

__obex_connect: error=-2

As you can see from the /var/log/messages file below, I don't get past the 'pin_code_request'.

My bluez config is this:-

I'm using CentOS 5 with BlueZ:-


# hciconfig hci0 revision
hci0: Type: USB
BD Address: 00:16:15:14:13:12 ACL MTU: 384:8 SCO MTU: 64:8
HCI 19.2
Chip version: BlueCore4-ROM
Max key size: 128 bit
SCO mapping: HCI


options {
autoinit yes;
security auto;
pairing multi;
passkey "0000";

device {
name "Test";
class 0x120104;
iscan enable; pscan enable;
lm accecpt;
lp rswitch,hold,sniff,park;

I have also created /etc/bluetooth/passkeys/default which contains only 0000

I've seen others mention passkey-agent, but I don't have this with my version of bluez-utils.

I've also seen people in the past adding pin_helper to hcid.conf but I believe this has now been replaced by the passkey option.

Lastly I've seen people talking about dbus, but this is an area I'm unfamiliar with and have only found /etc/dbus-1/system.d/bluez-hcid.conf which isn't very clear.

Can someone point me in the right direction please as it doing my head in now!

Thanks in advance...
