Hi,

I tried my first python script for accessing bluez through dbus. The bluez
setup is complete and I can scan and connect bluetooth devices using hcitool
and rfcomm tools. The dbus setup is working as well, the "dbus-monitor
--system" shows bluez messages when starting bluez.

But, I tried to run the following python script (and several other examples
from the internet):


import dbus
bus = dbus.SystemBus();
obj = bus.get_object('org.bluez', '/org/bluez')
manager = dbus.Interface(obj, 'org.bluez.Manager')
print manager.ListAdapters()


The output from this script is:

Traceback (most recent call last):
  File "./mydbus.py", line 27, in ?
    print manager.ListAdapters()
  File "/usr/lib/python2.4/site-packages/dbus/proxies.py", line 85, in
__call__
    return self._proxy_method(*args, **keywords)
  File "/usr/lib/python2.4/site-packages/dbus/proxies.py", line 169, in
__call__
    reply_message =
self._connection.send_message_with_reply_and_block(message, timeout)
dbus.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method
"ListAdapters" with signature "" on interface "org.bluez.Manager" doesn't
exist

On starting /etc/init.d/bluetooth, dbus-monitor --system shows:

$ dbus-monitor --system
signal sender=org.freedesktop.DBus -> dest=:1.5 path=/org/freedesktop/DBus;
interface=org.freedesktop.DBus; member=NameAcquired
   string ":1.5"
signal sender=org.freedesktop.DBus -> dest=(null destination)
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus;
member=NameOwnerChanged
   string ":1.6"
   string ""
   string ":1.6"
signal sender=org.freedesktop.DBus -> dest=(null destination)
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus;
member=NameOwnerChanged
   string "org.bluez"
   string ""
   string ":1.6"
signal sender=:1.6 -> dest=(null destination) path=/org/bluez/Manager;
interface=org.bluez.Manager; member=DeviceAdded
   string "/org/bluez/Device/hci0"
signal sender=:1.6 -> dest=(null destination) path=/org/bluez/Device/hci0;
interface=org.bluez.Device; member=Up
signal sender=:1.6 -> dest=(null destination) path=/org/bluez/Device/hci0;
interface=org.bluez.Device; member=PropertyChanged
   string "name"
   string ""

What is wrong here?

Thanks,
--theHog

Upgrading to v3.20 fixed it. Thanks :-)
