Hi,
You can try out couple of steps, to test ...
1. whether the change in "security" settings actually reflect on interface..
Try and pair with the device, with security "none" or "auto", and if you get relevant messages on remote device, then its fine.
2. If the above is successful, then it must be something very specific to obex lib you are using, I've used obexftp + openObex and didn't find any such problems. [with security "none" and "auto"]
Regards,
Pavan

Hi, Pavan
Thanks for your reply. I had tried this before, and tried it again
just now, but it still doesn't work.
The following are my steps, pls help to check if I missed any steps, THX!
1. change "security user;" to "security none;" in /etc/bluetooth/hcid.conf
2. Restart the bluetooth service: # /etc/init.d/bluetooth restart
3. (Optional: I tried twice, once with this step, and the other without)
Start passkey-agent: # passkey-agent --default 1234
4. ussp-push --dev 0 --debug 00:01:02:03:04:05@11 desk.jpg desk.jpg &
root@debian:~/bluetooth#
pushing file desk.jpg
name=desk.jpg, size=24762
__obex_connect: client_context_t = 0x80540f0
Registered transport
Set user data
Created new objext
cobex_write
Local device 00:01:02:03:04:01

my /etc/bluetooth/hcid.conf configuration are as following:
-------------------------------------------------------------------------
# HCId options
options {
autoinit yes;
security none;
pairing multi;
passkey "1234";
}
# Default settings for HCI devices
device {
name "pass1234";
# Local device class
class 0x3e0100;
# Default packet type
#pkt_type DH1,DM1,HV1;
# Inquiry and Page scan
iscan enable; pscan enable;
# Default link mode
lm accept;
# Default link policy
lp rswitch,hold,sniff,park;
}
-------------------------------------------------------------------------
Is this configuration correct?
My Linux version is:
root@debian:~/bluetooth# uname -a
Linux debian 2.6.18-6-686 #1 SMP Sun Feb 10 22:11:31 UTC 2008 i686 GNU/Linux
Any more information needed?
THX
