将 SDP 服务记录添加到 Raspberry Pi 3

Question

我正在尝试将 sdp 服务记录添加到我的 Raspberry Pi 3

import dbus

bus = dbus.SystemBus()

service = dbus.Interface(self.bus.get_object("org.bluez", "/org/bluez/hci0"),"org.bluez.Service")

service.AddRecord(SERVICE_RECORD)

但我总是遇到这个错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 70, in __call__

    message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "AddRecord" with signature "s" on interface "org.bluez.Service" doesn't exist

不知道AddRecord()函数有什么问题

有什么想法吗？

Answer 1

您的代码基于一些非常旧的 Bluez API：org.bluez.Service 接口在很多年前就被删除了。

如果您想在现代 linux 中使用现代 Bluez 完成相同的任务，请查看 Profile API and how the example tool 添加服务记录。

Answer 2

 UUID = "00000000-0000-1000-8000-00805F9B34FB"
 service_record = self.read_sdp_service_record()
 opts = {
        "AutoConnect": True,
        "RequireAuthentication":False,
        "RequireAuthorization":False,
        "ServiceRecord": service_record
 }
 bus = dbus.SystemBus()
 manager = dbus.Interface(bus.get_object(
        "org.bluez", "/org/bluez"), "org.bluez.ProfileManager1")
 manager.RegisterProfile("/org/bluez/hci0", UUID, opts)
