如何获取设备名称与D-Bus？

问题描述

我在Linux上使用C ++开发应用程序，它与蓝牙设备（如蓝牙插座或扬声器）交互。
我使用D-Bus命令获取配对设备列表：

dbus-send --system --dest = bluez --print-reply $ BTADAPTER org.bluez.Adapter.ListDevices

它返回：

 方法return sender =：1.0  - > dest =：1.90 reply_serial = 2 
 array [
对象路径/ org / bluez / 489 / hci0 / dev_00_1F_C5_75_45_5E
对象路径/ org / bluez / 489 / hci0 / dev_F0_13_C3_00_A1_08
 object path/ org / bluez / 489 / hci0 / dev_00_11_12_30_76_21
对象路径/ org / bluez / 489 / hci0 / dev_00_11_12_30_76_22
对象路径/ org / bluez / 489 / hci0 / dev_00_11_12_30_76_23
对象路径/ org / bluez / 489 / hci0 / dev_00_11_12_30_76_24
] 
  

这是伟大的，但我不仅需要MAC，而且还需要设备名称（例如linvor或GT-I9300）。

解决方案

尝试这个命令：dbus-send --system --type = method_call --print-reply --dest = org.bluez/ org / bluez / 489 / hci0 / dev_00_1F_C5_75_45_5Eorg.bluez.Device.GetProperties，您将获得有关该设备的所有信息

I develop an application in C++ on Linux, which interacts with blueooth devices (such as bluetooth sockets or speakers).I use D-Bus command to get list of paired devices:

dbus-send --system --dest=org.bluez --print-reply $BTADAPTER org.bluez.Adapter.ListDevices

It returns:

method return sender=:1.0 -> dest=:1.90 reply_serial=2
   array [
      object path "/org/bluez/489/hci0/dev_00_1F_C5_75_45_5E"
      object path "/org/bluez/489/hci0/dev_F0_13_C3_00_A1_08"
      object path "/org/bluez/489/hci0/dev_00_11_12_30_76_21"
      object path "/org/bluez/489/hci0/dev_00_11_12_30_76_22"
      object path "/org/bluez/489/hci0/dev_00_11_12_30_76_23"
      object path "/org/bluez/489/hci0/dev_00_11_12_30_76_24"
   ]

It is great, but I need not only MACs, but names of devices also (e.g. "linvor" or "GT-I9300").

Please, help me with a proper way to get those names.

解决方案

Try this command: dbus-send --system --type=method_call --print-reply --dest=org.bluez "/org/bluez/489/hci0/dev_00_1F_C5_75_45_5E" org.bluez.Device.GetProperties , you will get all information about that device
