Karmic Modemmanagers

Registered by Alexander Sack on 2009-06-18


In future connection managers will use modemmanager or compatible implementations to provide enhanced (3G) modem functionality. NetworkManager support will officially be available in 0.8; however, in order to provide options for downstreams and OEMs to make use of enhanced modem features, this spec suggests to maintain a modemmanager enabled build for the NetworkManager 0.7.1 branch; also it suggests to provide modemmanager as well as wader - a modemmanager compatible implemenation based on the VMC code (using python).

User A wants to know the signal strength while being connected to a 3G network, with modemmanager he can just see the current signal strength similar to the wifi signal strength in the applet tray icon

User B roams and wants to scan for available networks; after getting a list of available ones he wants to create a 3G connection configuration from it; with modemmanager he can scan from within network-manager applet and create a broadband configuration based on the scan results

User C wants to change the PIN on his sim-card. With modemmanager he can do so in the nm-applet

User D wants to write a SMS sending application; modemmanager dbus api provides this feature and he does not need to care about the hardware details.

Don't ship modemmanager enabled NetworkManager in karmic; instead run a preview modemmanager PPA with the following packages:
+ modemmanager
+ wader (modemmanager replacement based on VMC)
+ network-manager 0.7.x (with modemmanager patches)
+ network-manager-applet 0.7.x (with modemmanager patches)
+ connman (modemmanager enabled - if upstream version available in karmic supports this feature).

(asac) all but the QA testplan there. I think its ok to mark this implemented.

(asac) lightweight spec without wiki page, because its about providing modemmanager preview in a PPA (not real archive). Please sign off anyway, and parse work items.

(asac) for wader info see: http://trac.warp.es/wader/

pitti, 2009-06-19: Approving mini-spec, since this won't land in karmic.
