无法连接到蓝牙设备（org.bluez.Error.ConnectionAttemptFailed）

无法连接到蓝牙设备（org.bluez.Error.ConnectionAttemptFailed）

我无法连接*蓝牙设备。扫描将在几分钟后找到我的设备，但配对将失败。使用设置 GUI 时，它会将我的设备显示为“未设置”。单击它会显示一个旋转的轮子一分钟，之后它将返回到“未设置”。

使用 bluetoothctl，当尝试配对设备时，出现“org.bluez.Error.ConnectionAttemptFailed”

尝试将几种不同的蓝牙设备（耳机、扬声器、手机）与计算机配对时发生这种情况。

当前运行的是 Ubuntu 20.04（从 18.04 升级而来），内核为 5.4.0-37-generic

我在这台计算机上运行 18.04 时遇到了同样的问题，同时使用 20.04 live-USB 也排除了我可能对默认值所做的任何更改。

我的蓝牙设备是： 03:00.0 Network controller: Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] (rev 10)

我将不胜感激任何帮助！

*有几次，使用 bluetoothctl 时，我能够让它简短地显示已配对并连接，但之后它会立即显示已断开连接。我目前无法复制此情况。

更新

在解决问题上仍然没有取得任何进展，但我确实听到它说它已连接到设备并立即断开连接：

请检查以下内容：

确保该设备完全可用于新连接。
确保您已断开与所有其他设备的连接。
然后，重新启动连接的（旧设备）和蓝牙设备。

命令：

$ sudo bluetoothctl
[bluetooth]# power on
[bluetooth]# agent on
[bluetooth]# default-agent
[bluetooth]# scan on
[NEW] Device XX:XX:XX:XX:XX:XX 
[bluetooth]# scan off
