Description Ferry 2010-12-25 01:00:08 UTC
Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

When connecting a GSM over bluetooth modem-manager detect the GSM, however NetworkManager refuses to enable the Mobile Broadband tab so a DUN connection can be made.
syslog shows:
modem-manager	(/org/freedesktop/ModemManager/Modems/0): data port is rfcomm0
NetworkManager[723]	<info> ignoring modem 'rfcomm0' (no associated Bluetooth device)

Note that gnome-bluetooth wizard does exactly this.

As far as I know with KDE we do not have the possibility to add a DUN connection over a bluetooth GSM now.

Reproducible: Always

Now the only option is to use gnome-bluetooth AND network-manager-gnome. Bluedevil doesn't have any DUN support and only nm-applet provides a gnome-bluetooth plugin (which in turn knows only about nm-applet).

This is planned for the next version of NetworManagement, so we'll have this feature soon enough :p

Thanks for the wish.

Is there any experimental support in bluedevil git/knetworkmanager git?

This bluetooth modem thing is very weird.

1. If I do this as root (or normal user) with my cellphone:

evolucao # dbus-send --system --print-reply --dest=org.bluez
/org/bluez/25735/hci0/dev_<cell phone bluetooth MAC> org.bluez.Serial.Connect
method return sender=:1.119 -> dest=:1.245 reply_serial=2
   string "/dev/rfcomm0"

The entry /dev/rfcomm0 is not created although the reply says it should have
been created.

2. If I use qdbusviewer as normal user it creates the /dev/rfcomm0 entry and it
works with wvdial but ModemManager ignores /dev/rfcomm0 with no message in
/var/log/messages, just ignores.

3. If I do this as root:

INFO=$(LC_ALL=C sdptool search DUN | awk '/Searching for DUN on / { print $5 }
/Channel:/ { print " "$NF }')
MAC=$(echo $INFO | awk '{ print $1 }')
CHANNEL=$(echo $INFO | awk '{ print $2 }')

mknod --mode=666 /dev/rfcomm0 c 216 0
rfcomm connect 0 $MAC $CHANNEL

It works with both wvdial and ModemManager, and conseguently with Plasma NM. I
can connect with my cellphone and browse the Internet normally. The last weird
thing is that even though everything is working ModemManager does not get the
access technology used, Edge in this case.

Updates for bluetooth tethering support.

Full support only in KDE SC 4.7.0 because Plasma NM needs Solid 4.7.0 to
detect bluetooth network interfaces. In the mean time Plasma NM will treat
bluetooth network interfaces as gsm network interfaces. I still need to
implement bluetooth tethering for Cdma phones and Gsm/Cdma) Panu.

Without Solid 4.7.0 Plasma NM will not list the bluetooth interface nor
the bluetooth connection, so the only way to connect is setting the
bluetooth connection to autoconnect. There will be no notifications from
knotify either without Solid 4.7.0 and of course interface details tab
will not work because the interface is not listed.

Soon Bluedevil will be updated to automatically call the wizard. Until then you can use networkmanagement_configshell command to register a bluetooth DUN (dial-up network) connection using the steps in here:

Comment 9 Alex Fiestas 2011-10-08 13:08:27 UTC
This is done now since BlueDevil 1.2 and NetworkManagement 0.9-beta

Thanks for reporting and giving feedback !
