I was excited, because I already have a snippet that sets the ‘Alias’ of the same interface, so I thought I could just modify a little: #!/usr/bin/env python3 import dbus import dbus.mainloop.glib import gi.repository.GLib as glib import os import sys Adapter = '/org/bluez/hci0' def main(): dbus.mainloop.glib.DBusGMainLoop(set_as_default=True) bus = dbus.SystemBus() adapterProperties = dbus.Interface(bus.get_object('org.bluez', Adapter), 'org.freedesktop.DBus.Properties') value = adapterProperties.Get('org.bluez.Adapter1', 'Connected') print('connected', value) mainloop = glib.MainLoop() try: mainloop.run() except KeyboardInterrupt: mainloop.quit() if __name__ == '__main__': main() Unfortunately, that doesn’t work. I got the following error: root@nelson:/Pilot# ./connected Traceback (most recent call last): File "./connected", line 28, in <module> main() File "./connected", line 17, in main value = adapterProperties.Get('org.bluez.Adapter1', 'Connected') File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 70, in __call__ return self._proxy_method(*args, **keywords) File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 145, in __call__ **keywords) File "/usr/lib/python3/dist-packages/dbus/connection.py", line 651, in call_blocking message, timeout) dbus.exceptions.DBusException: org.freedesktop.DBus.Error.InvalidArgs: No such property ‘Connected' My original code had a .Set() call, but maybe I was naive in assuming that a .Get() would be the converse? Do I even need to do the runloop thing in this case?-- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
