我连接到我的新 K380无需配对过程使用蓝牙管理器。之后,使用一段时间后,我发现键盘不再有反应,我总是重新连接它才能正常工作。
我想知道是否有命令行方式来配对,因为蓝牙管理器说存在“设备配对问题”。
我将 Ubuntu 20.04 与 Dell Latitude e5450 和 Intel Wireless 7265 (rev 59) 结合使用
答案1
该问题的作者提供了以下解决方案。
bluetoothctl
如果尚未安装,请安装。在 Ubuntu 20.04 中它是默认安装的。
在终端中,运行命令bluetoothctl
:
$ bluetoothctl
Agent registered
[MX Vertical]# agent on
Agent is already registered
开始扫描:
[MX Vertical]# scan on
Discovery started
[CHG] Controller DC:53:60:0E:0A:C8 Discovering: yes
[CHG] Device 34:88:5D:EF:19:51 RSSI: -49
[CHG] Device 34:88:5D:EF:19:51 Class: 0x00002540
[CHG] Device 34:88:5D:EF:19:51 Icon: input-keyboard
[CHG] Device 88:0F:10:87:00:F1 RSSI: -87
在此输出中,键盘的 MAC 地址为:34:88:5D:EF:19:51。复制它!然后停止扫描:
[MX Vertical]# scan off
[CHG] Device 88:0F:10:87:00:F1 RSSI is nil
[CHG] Device 34:88:5D:EF:19:51 RSSI is nil
[CHG] Controller DC:53:60:0E:0A:C8 Discovering: no
Discovery stopped
通过以下方式信任设备:
[MX Vertical]# trust 34:88:5D:EF:19:51
[CHG] Device 34:88:5D:EF:19:51 Trusted: yes
Changing 34:88:5D:EF:19:51 trust succeeded
并将其配对。现在,必须在键盘中输入终端中显示的密钥(在本例中为 300892),然后Enter按 a。它看起来像这样:
[MX Vertical]# pair 34:88:5D:EF:19:51

[CHG] Device 34:88:5D:EF:19:51 Connected: yes

[agent] Passkey: 0892
[agent] Passkey: 892
[agent] Passkey: 92
[agent] Passkey: 2
[agent] Passkey:
现在就打Enter。
