Q: nm-gsm-device.c
Hello, I am a newbie student of the NetworkManager, and I try to undetsrand the way the application treats with modem & wifi devices (more ineterseted in the low level parts of the NetworkManager application: the "commands" to the devices). I saw that in the older released version such as 0.7.2 there was a file /src/nm-gsm-device.c which contained some of the AT-COMMAND used for initialization of modems, but in the updated version there is no such file(as far as I can find), and I dont see anywhere else where AT-Command are used. Does anyone knows how these commands are used then in the updated version ?

How nm-applet and gnome-bluetooth interact to create a bluetooth connection?
Hi all,
Alex Fiestas and me are trying to implement Bluetooth DUN support for
KDE. We spent some time trying to figure out the steps nm-applet and gnome-
bluetooth do to implement it but without much success. Can someone help us?
During my tests I hit this part of NM code in src/nm-manager.c:
/* If it was a Bluetooth modem and no bluetooth device claimed it,
ignore
* it. The rfcomm port (and thus the modem) gets created automatically
* by the Bluetooth code during the connection process.
*/
if (driver && !strcmp (driver, "bluetooth")) {
nm_log_info (LOGD_MB, "ignoring modem '%s' (no associated
Bluetooth
device)", ip_iface);
return;
}
Commenting the "return" allows me to use my cellphone as bluetooth
serial
modem (after creating /dev/rfcomm0 using BlueZ), but of course I guess that
code is there for a reason. I still do not understand how gnome-bluetooth (or
nm-applet) creates the rfcomm port. I know that can be done using BlueZ's DBus
interface by calling the org.bluez.Serial.Connect method on a bluetooth
device. But since NM is explicitly ignoring the rfcomm port, how are NM's
bluetooth connections supposed to work?

no wireless networks detected
Hi, My networkmanager is not automatically detecting the dozen or so wireless networks surrounding me, even though it used to do so earlier, until i had to reninstall the system from scratch. All drivers etc are installed and all versions of the OS and network manager are the same. Earlier it used to work. Now it doesn't.

Modem-/NetworkManager support for modems not using PPP
Hi! There seems to be now quite a bit of modems appearing now that does not support the old method of using PPP protocol on the same tty device as the AT commands are sent, or it is not recommended for higher HSPA+ and LTE modems because of performance limitations of the PPP/tty layer. Those devices typically accept AT commands at one interface and use another interface for the network traffic (including first a DHCP query). One example is the Samsung GT-B3730 I'm currently developing drivers for: https://github.com/mkotsbak/Samsung-GT-B3730-linux-driver It seems to be the same case for LG VL600 4G (LTE): http://ubuntuforums.org/showpost.php?p=10589647&postcount=17 https://github.com/balrog-kun/LG-VL600-utils The Ericsson Mobile Broadband Modules (I have an F5521gw based modem) seems to offer both the old ACM ports and support USB WCM / CDC NCM / CDC Ethernet protocols for higher performance: http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module#Connecting_to_the_net_via_CDC_Ethernet_interface http://sourceforge.net/apps/mediawiki/mbm/index.php?title=MBM#Prerequisites http://cateee.net/lkddb/web-lkddb/USB_NET_CDC_NCM.html I wonder if support for this has been implemented or thought about in Modem-/NetworkManager. We probably need a flag for a modem manager module to tell that it does not use PPP and require to get IP address using DHCP instead. Else those devices benefit from the code in modem manager (and should be classified as such to the user as well), like the PIN unlocking, signal strength (typically found on the same device as dialling happened, since network traffic flow on a separate interface) etc. The configuration tab for PPP could be hidden for those devices. For devices offering multiple ways to connect, the modem manager module should probably find the best performing according to the available kernel modules and use that method. -- Marius Kotsbak ___ networkmanager-list mailing list networkmanager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list
