Hi,
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.
My code is all Python, and I need to do some stuff like
- getting notified if the device is plugged in to the charger or not
(saw some examples of that)
- 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).
First issue:
From the "python_maemo_howto" - "One of LibOSSO's main features is RPC
(Remote Procedure Calls) services (as it "wraps" D-Bus ^3
<http://pymaemo.garage.maemo.org/documentation/pymaemo_tutorial/python_maemo_howto.html#references_maemo_sdk_tutorial>)"
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.
So which is it? OSSO.RPC or the dbus module?
Can anyone point me to the difference between these two wrappers of the
D-Bus?
Are there cases where one is better than the other?
Second issue- controlling the WLAN connection
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?
Can I have access to all of the settings that are possible through the
network configuration GUI application?
Is there any example of setting WLAN connection and IP settings (e..g
static IP address) through python?
Any info would be appreciated,
Thanks!

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):
import dbus
import dbus.glib
import gobject
main_loop = None
def disc_completed_signal():
print 'Signal: DiscoveryCompleted()'
main_loop.quit()
class dbus_bluetooth:
def __init__(self):
self.bus = dbus.SystemBus()
def set_callback(self, f_callback):
self.bus.add_signal_receiver(f_callback, 'RemoteNameUpdated',
'org.bluez.Adapter', 'org.bluez',
'/org/bluez/hci0')
self.bus.add_signal_receiver(disc_completed_signal,
'DiscoveryCompleted',
'org.bluez.Adapter',
'org.bluez', '/org/bluez/hci0')
self.obj = self.bus.get_object('org.bluez', '/org/bluez/hci0')
self.adapter = dbus.Interface(self.obj, 'org.bluez.Adapter')
def discover(self):
global main_loop
self.adapter.DiscoverDevices()
gobject.threads_init()
dbus.glib.init_threads()
main_loop = gobject.MainLoop()
main_loop.run()
def test(address, name):
print 'Got a device: (%s, %s)' % (address, name)
obj = dbus_bluetooth()
obj.set_callback(test)
obj.discover()
Best regards
