Hi,<br>
<br>
I've never used the D-Bus before and I realized its probably time for
me to start. After doing some reading on this list and whatever Google
brought up I am a bit confused as to what I should be using and how.<br>
<br>
My code is all Python, and I need to do some stuff like<br>
- getting notified if the device is plugged in to the charger or not
(saw some examples of that)<br>
- modifying the network interfaces (both IP addresses and connecting to
access points and ad-hoc networks). So far I've done this with ifconfig
and iwconfig but it was definitely a hack, plus my device used to crash
a lot, which I attribute to collisions between my manual changes and
the connection daemons).<br>
<br>
First issue:<br>
>From the "python_maemo_howto" - "One of LibOSSO's main features is RPC
(Remote Procedure Calls) services (as it "wraps" D-Bus <a
moz-do-not-send="true"
href="http://pymaemo.garage.maemo.org/documentation/pymaemo_tutorial/python_maemo_howto.html#references_maemo_sdk_tutorial"><sup>3</sup></a>)"<br>
>From the example posted by Adenilson Cavalcanti just today (at the end
of this email), I saw he used the python d-bus module, which wasn't
mentioned in any of the other tutorials on maemo.org, but I later found
it on the PyMaemo page.<br>
<br>
So which is it? OSSO.RPC or the dbus module?<br>
Can anyone point me to the difference between these two wrappers of the
D-Bus? <br>
Are there cases where one is better than the other? <br>
<br>
Second issue- controlling the WLAN connection<br>
>From my reading I saw that for the networking stuff I would need to
connect to "wlancond" and to "ICD". I saw discussions about them not
being open source, but that there is some API available. Could anyone
direct me to those APIs and some way to use them through Python?<br>
Can I have access to all of the settings that are possible through the
network configuration GUI application?<br>
Is there any example of setting WLAN connection and IP settings (e..g
static IP address) through python?<br>
<br>
Any info would be appreciated,<br>
Thanks!<br>

Long time since the last message...<br>

Got it working using D-Bus, with this code based on the sample code of
BlueZ wiki page (hope that it don't break formating):<br>
<br>
<br>
import dbus<br>
import dbus.glib<br>
import gobject<br>
<br>
main_loop = None<br>
<br>
def disc_completed_signal():<br>
print 'Signal: DiscoveryCompleted()'<br>
main_loop.quit()<br>
<br>
<br>
class dbus_bluetooth:<br>
def __init__(self):<br>
self.bus = dbus.SystemBus()<br>
def set_callback(self, f_callback):<br>
self.bus.add_signal_receiver(f_callback, 'RemoteNameUpdated',<br>
'org.bluez.Adapter', 'org.bluez',<br>
'/org/bluez/hci0')<br>
self.bus.add_signal_receiver(disc_completed_signal,<br>
'DiscoveryCompleted',
'org.bluez.Adapter',<br>
'org.bluez', '/org/bluez/hci0')<br>
self.obj = self.bus.get_object('org.bluez', '/org/bluez/hci0')<br>
self.adapter = dbus.Interface(self.obj, 'org.bluez.Adapter')<br>
def discover(self):<br>
global main_loop<br>
self.adapter.DiscoverDevices()<br>
gobject.threads_init()<br>
dbus.glib.init_threads()<br>
main_loop = gobject.MainLoop()<br>
main_loop.run()<br>
<br>
def test(address, name):<br>
print 'Got a device: (%s, %s)' % (address, name)<br>
<br>
obj = dbus_bluetooth()<br>
obj.set_callback(test)<br>
obj.discover()<br>
<br>
Best regards<br>
