Harald, your script looks familiar to me. Over the years I’ve been contributing many bits and pieces to my script. It is at
https://api.opensuse.org/public/source/home:jnweiger/jw-settings/bluetooth-internet.sh

Seife, this is what test-network does to me on my 11.2 box:
test-network 00:xx:xx:xx:xx:xx nap
Traceback (most recent call last):
File “/usr/bin/test-network”, line 31, in
iface = network.Connect(service)
File “/usr/lib/python2.6/site-packages/dbus/proxies.py”, line 68, in __call__
return self._proxy_method(*args, **keywords)

In case anyone is interested in the “old method” and likes to improve my initial script (still with many debug output):
———————————————————————–
#!/bin/bash
# config section
# configure your BLUEZ ID
BLUEZID=”00:XX:XX:XX:XX:XX”
# after suspend/resume cycle bluetooth might be off
echo enable > /proc/acpi/ibm/bluetooth
# short sleep to make sure bluethooth is ready
sleep 1
# Channel for dial up network via bluetooth might change
# (experienced with Nokia E71 after turning bluetooth off/on)
# re-set channel each time

# release all rfcoom devices
rfcomm release all
# get current active dialup network channel
RFCHANNEL=`sdptool browse $BLUEZID | \
grep -A4 “Dialup Networking” | \
awk ‘$1 == “Channel:” {print $2}’`
# print out channel for debugging reasons
echo Channel is: $RFCHANNEL
# bind rfcomm0 to channel and device (bind all not always successful)
rfcomm bind rfcomm0 $BLUEZID $RFCHANNEL
# DEBUGGING check if rfcomm0 has been setup correctly
rfcomm
# Finally dial in
wvdial umts

Hi, sadfully this approach doesn’t seem to work with 11.1.
bluez-test there misses test-network and even installing an uptodate bluez package doesn’t work but brings a connection refused error.

Thank you, NICE. Interesting to read, even though my phone does not support it.
“Old method” using rfcomm via some scripts still work, but I would prefer the PAN approach.

I have to check my wifes new phone.
