20.04 - Logitech MX Keys 无法与蓝牙配对

Question

我正在使用 Ubuntu 20.04.1，我正在尝试通过蓝牙配对我的 MX Keys 键盘。

\n

我使用蓝牙控制面板启动该过程，然后卡在这个窗口中。

\n

\n

即使我输入正确的 PIN 码并按 ENTER，该过程仍然没有完成。事实上，它会陷入该模式，无法关闭 PIN 窗口。

\n

我也尝试过使用“Blueman”，得到了类似的结果。我开始“设置”过程，这就是我最终得到的。

\n

我也尝试过bluetoothctl

\xe2\x9e\x9c bluetoothctl connect CB:DD:B4:5C:4E:E3\nAttempting to connect to CB:DD:B4:5C:4E:E3\n[CHG] Device CB:DD:B4:5C:4E:E3 Connected: yes\nConnection successful\n\n~ took 8s \n\xe2\x9e\x9c bluetoothctl trust CB:DD:B4:5C:4E:E3\n[CHG] Device CB:DD:B4:5C:4E:E3 Trusted: yes\nChanging CB:DD:B4:5C:4E:E3 trust succeeded\n\n~ \n\xe2\x9e\x9c bluetoothctl pair CB:DD:B4:5C:4E:E3\nAttempting to pair with CB:DD:B4:5C:4E:E3\n[CHG] Device CB:DD:B4:5C:4E:E3 ServicesResolved: yes\n[CHG] Device CB:DD:B4:5C:4E:E3 ServicesResolved: no\n[CHG] Device CB:DD:B4:5C:4E:E3 Connected: no\nFailed to pair: org.bluez.Error.AuthenticationCanceled\n\n~ took 30s \n\n

\n

可以做些什么来让它发挥作用？

\n

更新

\n

如果我重置电脑中的蓝牙，我已设法获取 PIN bluetoothctl，但即使输入 PIN，身份验证也会失败。就好像它忽略了我输入的内容......

\n

[bluetooth]# pair CB:DD:B4:5C:4E:E3\nAttempting to pair with CB:DD:B4:5C:4E:E3\n[CHG] Device CB:DD:B4:5C:4E:E3 Connected: yes\n[agent] Passkey: 610148\n[CHG] Device CB:DD:B4:5C:4E:E3 Connected: no\nFailed to pair: org.bluez.Error.AuthenticationCanceled\n

Answer 1

这适用于 Xubuntu (Ubuntu 20.04.3 LTS) 上的 Logitech MX Keys Mini。

打开终端并运行以下命令：

bluetoothctl
power off
power on
agent KeyboardOnly
default-agent
pairable on
scan on
pair <mac address>
## the passkey will be printed, enter it on your keyboard ##
trust <mac address>
connect <mac address>
quit

Answer 2

我在使用联想键盘时也遇到了同样的问题。基本上我可以输入密码，但按回车键后什么也没有发生。

$bluetoothctl
[bluetooth]# agent KeyboardDisplay
[bluetooth]# default-agent 
[bluetooth]# scan on
[bluetooth]# pair <MAC-address>
Attempting to pair with <MAC-address>
[CHG] Device <MAC-address> Connected: yes
[agent] Passkey: xxxxxx
[agent] Passkey: xxxxx
[agent] Passkey: xxxx
[agent] Passkey: xxx
[agent] Passkey: xx
[agent] Passkey: x
[agent] Passkey: 
[CHG] Device <MAC-address> Modalias: usb:<ALIAS>
[CHG] Device <MAC-address> UUIDs: <UUID>
[CHG] Device <MAC-address> ServicesResolved: yes
[CHG] Device <MAC-address> Paired: yes
Pairing successful
[CHG] Device <MAC-address> ServicesResolved: no
[CHG] Device <MAC-address> Connected: no
[CHG] Device <MAC-address> Class: 0x00000540
[CHG] Device <MAC-address> Icon: input-keyboard
[CHG] Device <MAC-address> Connected: yes
Authorize service
[agent] Authorize service <UUID> (yes/no): yes

[agent] Authorize serviceGUI 中似乎没有显示最后一步

我修复了它，安装了一些丢失的固件。我所要做的就是运行这个命令：

cd /lib/firmware/brcm && sudo wget https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM20702A1-0a5c-21e8.hcd

然后拔下并再次插入我的蓝牙适配器
