[kwlug-disc] Barry (Solved)

[Chris Frey]

Hi Richard,

Barry, so far, only provides the low level communication utilities.
i.e. it provides pppob, which you can hook into pppd to gain modem
functionality over USB.  Any easier way to do this is done by other
GUI tools, if they exist.

Since bluetooth support is provided by the kernel, you can use the
same low level techniques you might use with Barry, for Bluetooth.

You can find some notes from Michael Brown at the end of the
doc/www/modem.php file, on setting up Bluetooth:

	http://repo.or.cz/w/barry.git/blob/HEAD:/doc/www/modem.php

I'll copy them here.  Basically, put the following in your
/etc/bluetooth/rfcomm.conf file, replacing the X's with your Bluetooth BADDR.

rfcomm0 {
	bind yes;
	device XX:XX:XX:XX:XX:XX;
	channel 1;
	comment "Blackberry Dialup";
}


Then in your usual peer file (/etc/ppp/peers/barry-rogers, for example),
remove the pty line and add:

/dev/rfcomm0
115200

- Chris

Yet on one laptop modem-manager refused the dbus calls from blueman. I'm guessing this is probably caused by something legacy, left behind after upgrading to 10.10. I've tried adjusting permissions and the policy for modem-manager with no luck... I suppose I should test this off a live cd to be certain if it's config related.
