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 Remote device 00:01:02:03:04:05 (11) Write error: Transport endpoint is not connected obex_event: client_context_t = 0x80540f0 cobex_disconnect Link broken!

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?
