Bug Description

USB modeswitching works ok, and the network operator appears in the NM menu, but it fails to connect.

Nm-applet needs to be updated upstream. See the same change for Gnome shell:

https://bugzilla.gnome.org/show_bug.cgi?id=687359

We also need libqmi packaged, see bug #1075801.

Indeed. The new ModemManager (0.7) will export a modem in a 'Failed' state whenever a fatal SIM error occurs (e.g. no SIM card). Providing more information on why the modem went into this 'Failed' state could help to make UIs expose the real reason.

Andy Whitcroft, is there any reason for this, or could it be changed to be enabled in the next kernels built there and later for Ubuntu?

Hmm, i see in http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc7-precise/BUILD.LOG

"QMI WWAN driver for Qualcomm MSM based 3G and LTE modems (USB_NET_QMI_WWAN) [N/m/?] (NEW) Option USB High Speed Mobile Devices (USB_HSO) [M/n/y/?] m"

Seems like there is a missing answer to the question about this module.

I guess modemmanager should communicate with the new /dev/cdc-wdm0 instead of wwan0.

There is work in progress already to use the cdc-wdm0 interface for QMI with libqmi in ModemManager.

Japp, I saw there were a branch for that in modemmanager at master branch, but I was not able to get it running with the current Networkmanager in Ubunt. Also I was not able to get NM from master branch to work. Do I need to replace the nm-applet too?

Do you know if there is an easy way to get the master version built for Ubuntu? It seems like the packages available in the PPAs are outdated or use the stable branches.

Still quite some things to do before being able to use QMI in ModemManager, including finishing to port all pending MM plugins to the new codebase, and updating NetworkManager to talk to the new redesigned interface... Current MM git master is not yet able to talk to NM git master.

Help really welcome :-)

I verified that the kernel for 12.10 works using NetCom in Norway by testing with libqmi-glib by running:

* qmi-network /dev/cdc-wdm0 start
* dhclient wwan0

Would it be possible to backport the qmi support to a stable NM/MM? Rebasing the branch to 0.6 did not work without conflicts.

Before this is fixed, for Ubuntu 12.10, we need an updated modemmanager version containing the following commit

Backporting the QMI support from MM git master (0.7) to 0.5/0.6 is a thousand times more complex than improving NetworkManager to support MM 0.7, which is anyway something planned to be done. Help welcome :-)

ModemManager >= 0.7 will come with an improved DBus interface. Documentation about this interface can be seen at:
http://www.lanedo.com/~aleksander/modem-manager/api-20121005/api/ref-dbus.html

In order to ease the integration of the new ModemManager, headers with enums/error definitions are also available:
http://cgit.freedesktop.org/ModemManager/ModemManager/tree/include

There's also a new 'libmm-glib', which helps to integrate ModemManager in glib-based applications, although not sure if this is really desirable here:
http://www.lanedo.com/~aleksander/modem-manager/api-20121005/libmm-glib/

Some basic hints:
* NetworkManager will expose Modems handled by the new ModemManager with a UDI prefixed with "/org/freedesktop/ModemManager1/Modem/".
* SIMs are exposed as independent DBus objects. You'll need to get the SIM object path, if any, from the 'Modem' interface. PIN unlocking is done directly in the SIM interface of the SIM object.
* Both 3GPP (a.k.a. GSM) and 3GPP2 (a.k.a. CDMA) modems are now handled in the same way. The new ModemManager exposes in 'CurrentCapabilities' in the modem interface which capabilities are supported. It is expected to have modems which are both 3GPP and 3GPP2 (e.g. LTE+CDMA modems).
* For connecting/disconnecting, using the Simple interface is still the simplest way for now. The new ModemManager can handle multiple data bearer configurations if directly playing with creating bearer objects and connecting them independently (the Simple interface can't do that yet).
* DBus interfaces are dynamic. E.g. a modem exposing the Messaging interface will have messaging (SMS) capabilities, otherwise the interface won't be exposed.
* When a modem is non yet PIN-unlocked, only the Modem interface and the SIM object will be available.

Reproducible: Always

Can be tested with latest git master for both NetworkManager and ModemManager.

Just to update the status of this bug. ModemManagerQt and NetworkManagerQt's master branch already support ModemManager1 interface. There is a mm1port branch in the new Plasma NM applet that also supports ModemManager1, so this bug is near to be closed as fixed.
