python下使用bluez报错：方法不存在

Question

代码：

$ python
>>> import dbus
>>> bus = dbus.SystemBus()
>>> manager = dbus.Interface(bus.get_object('org.bluez', '/org/bluez'), 'org.bluez.Manager')
>>> foo = manager.DefaultAdapter()

错误提示：

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "DefaultAdapter" with signature "" on interface "org.bluez.Manager" doesn't exist

Answer 1

dir(manager)查看所有方法和属性，有时候同样的库，版本不一样，方法也会不同

Answer 2

org.bluez.Service 在bluez5已经被移除 :

The removal of the org.bluez.Service interface (used for registering
SDP records and authorization) and the introduction of a new
org.bluez.Profile1 interface

4）移除org.bluez.Service接口（用于注册SDP records and
authorization），引入新的org.bluez.Profile1接口。
