清单附近/发现的蓝牙设备，包括已经配对，在Python中，在Linux上 [英] List nearby/discoverable bluetooth devices, including already paired, in Python, on Linux

问题描述

我想列出所有附近的/发现的蓝牙设备，的包括那些已经配对的，在Linux上使用Python。

I'm trying to list all nearby/discoverable bluetooth devices, including those already paired, using Python on Linux.

我知道如何使用它的地址列出的设备服务，并可以成功连接：

I know how to list services for a device using its address, and can connect successfully:

services = bluetooth.find_service(address='...')

读PyBluez文档我希望附近的任何设备露面，如果我不指定任何条件：

Reading the PyBluez docs I would expect any nearby device to show up if I don't specify any criteria:

如果没有指定条件，然后返回检测到附近所有服务的列表。

"If no criteria are specified, then returns a list of all nearby services detected."

唯一的事我现在需要的是能够列出已经配对的设备，无论是打开，关闭，附近还是不行。就像列表我得到的所有设置 - >蓝牙在Ubuntu /统一。

The "only" thing I need right now is to be able to list already paired devices, whether they are on, off, nearby or not. Much like the list I'm getting in All Settings --> Bluetooth in Ubuntu/Unity.

顺便说一下，以下的不的我的机器上已名单配对的设备，即使他们是在/在附近。大概是因为它们不会被发现，一旦配对：

Btw, the following does not list already paired devices on my machine, even if they are on/nearby. Probably because they are not discoverable once paired:

import bluetooth
for d in bluetooth.discover_devices(flush_cache=True):
    print d

任何想法...？

Any ideas ...?

编辑：我找到并安装bluez的工具

I found and installed "bluez-tools".

bt-device --list

...给我我需要的信息，即增加设备的地址。

... gives me the information I need, i.e. addresses of added devices.

我检查C源代码，发现了，因为我认为这将是这可能不是那么容易。

I've checked the C source, found out that this might not be as easy as I thought it would be.

还是不知道如何在Python中做到这一点...

Still don't know how to do this in Python ...

编辑：我想DBUS可能是什么，我应该在阅读起来。似乎很复杂。如果有人有一些code分享我会很高兴。 ：）

I think DBUS might be what I should be reading up on. Seems complicated enough. If anyone has got some code to share I would be really happy. :)

推荐答案

我设法解决自己的问题。下面的代码片段列出地址的所有配对设备，在我的默认蓝牙适配器：

I managed to solve the problem myself. The following snippet lists addresses for all paired devices, on my default bluetooth adapter:

import dbus

bus = dbus.SystemBus()

manager = dbus.Interface(bus.get_object('org.bluez', '/'), 'org.bluez.Manager')

adapterPath = manager.DefaultAdapter()

adapter = dbus.Interface(bus.get_object('org.bluez', adapterPath), 'org.bluez.Adapter')

for devicePath in adapter.ListDevices():
    device = dbus.Interface(bus.get_object('org.bluez', devicePath),'org.bluez.Device')
    deviceProperties = device.GetProperties()
    print deviceProperties["Address"]
