NetworkManager and ModemManager

[Marc Murphy <marcmltd marcm co uk>]

Hello,
I am trying to get NetworkManager and ModemManager to work together on an embedded system.  There is no GUI 
so I have to use the config files to set everything up.

Should network-manager-0.9.2.0 and modem-manager-0.7.990 work together using the dbus interface ?

I just cant seem to make them talk to each other !

NetworkManager can see my eth0 device;
# nmcli d
DEVICE     TYPE              STATE
eth0       802-3-ethernet    unmanaged

I have forced it to be unmamaged at the moment as I am running NFS and it will cause the boot connection to 
be lost and hang the system.

ModemManager can see the modem;
# mmcli -m 0

Should the two just talk to each other ? or do I need to set something up ?

I would like to make NetworkManager automatically connect the modem and get an IP address so I can use the 
connection.

Can anyone help me over this stumbling block please ?

Thanks
Marc
