MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Hi, all When pushing a file to bluetooth mobile phone from a Linux PC, how to disable bluetooth authentication mechanism (in kernel or user level ? ), so that the phone won't prompt a window ask for PIN code? I'm a freshman on bluez, now I'm trying to write an application on Linux PC, to send files to mobile phones with OBEX. The PC has a USB bluetooth stick to communication with the phone. Now I have successfully sent a file to phone using the following commands: 1. "hcitool scan" and "sdptool browse" 2. "passkey-agent --default 1234" and "ussp-push --dev 0 BTADDR@CHANNEL desk.jpg desk.jpg" but the phone ask for a PIN code at the start. To get rid of this, I had tried to comment out "start_security_manager()" in bluez-utils-3.7/hcid/main.c, and recompile it, then restart the bluetooth service. But PIN code was still prompted, and after if I input some characters, the command "ussp-push --dev 0 --debug BTADDR@CHANNEL desk.jpg desk.jpg", failed with the following error: 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!
