 Yes, depending on what kind of 'mobile' you have. First, get
networking to work. For example, if you have a Palm-based system, if
you can remote hotsync over bluetooth, then you should be able to do
remote desktop. There are several ways to remotely view the screen
with Linux. There's a linux RDP (Microsofts' "Remote Desktop
Protocol") server here: http://xrdp.sourceforge.net/

 However, I think the VNC stuff is a bit more mature. VNC is a
different implementation of the same 'remote desktop' idea. I've used
this on my Palm: http://palmvnc2.free.fr/

[Bluez-users] How to using security "Auto" in pairing , I tried but not working ?

[colorant]

Hi

    I do not have passkey-agent running , so I try to use auto for security 
and hope it can send back the passkey auto.

My setting in hcid.conf is as below :

options {
        # Automatically initialize new devices
        autoinit yes;

        # Security Manager mode
        #   none - Security manager disabled
        #   auto - Use local PIN for incoming connections
        #   user - Always ask user for a PIN
        #
        security auto;

        # Pairing mode
        #   none  - Pairing disabled
        #   multi - Allow pairing with already paired devices
        #   once  - Pair once and deny successive attempts
        pairing multi;

        # Do the same as "hciconfig hci0 down" when SetMode("off")
        # is called.
        offmode devdown;

        # Default PIN code for incoming connections
        passkey "1234";
}

But this don't work :

When I try to start the bonding process following 
http://wiki.bluez.org/wiki/HOWTO/Bonding
The output of hcidump :

According to the wiki, this is the senario that : no passkey agent available 
or rejection

But , Since I using security "auto", why it still looking for an agent ?

I found in some way , it works, as below:

I found the behavior is :

If I initiate a bonding through dbus, this won't working.
But if the bonding request is initiate from remote, this auto security 
setting can work , and will send the passkey as in the conf file.

If I using security user, and use passkey-agent --default <pin> as the 
agent.
Then , no matter the bonding is initiate from which side , it will always 
working.

Is the auto procedure designed to doing so  ?

Thanks.

Raymond
