The signal module is for handling process signals the operating system sends to your python process. The API you're using (dbus, a crucial detail you neglected to mention before) doesn't send this kind of signal. Googling for 'python dbus documentation' brings up http://dbus.freedesktop.org/doc/dbus-python/api/ , which seems to explain everything you need. You need to get an instance of dbus.Interface, which you seem to have done, and call its connect_to_signal() method, which you don't seem to have done. > I’d also like to know how i can keep the application running until I > decided to stop it manually, as the DiscoverDevices() can take a while > to complete and send out several RemoteDeviceFound() signals in that > period. The very first section of the above mentioned documentation talks about needing a main loop for receiving signals, and it provides example boilerplate code for how to set up a main loop. Hope this helps, Carsten. -- http://mail.python.org/mailman/listinfo/python-list
