UBUNTU 20.04 上的蓝牙不断断开连接

我已经在笔记本电脑上安装了 Ubuntu 20.04，但蓝牙似乎无法按预期工作。

它连接到我的 Logi MX ERGO 设备，也连接到我的 TWS 耳机，但运行一段时间后（显然是随机时间）它停止工作，所以我需要使用触摸板将蓝牙管理器或 bluesman 切换到 OFF 然后再打开，这样它就会自动连接到我的设备......但过一段时间它就会再次断开连接；

这是 grep blue /var/log/syslog 的输出

有人遇到过这个问题吗？我阅读了很多论坛主题并尝试了一些替代方案，但没有一个对我有用。

我将非常感激有关如何解决此问题的任何帮助或参考。

答案1

取消注释以下行可以/etc/bluetooth/input.conf帮我修复此问题：

UserspaceHID=true

确保systemctl restart bluetooth应用更改

答案2

我也遇到了同样的问题。找到了解决方案在 Reddit 上 在尝试以下步骤之前，请先完全断开您的设备：

跑步

bluetoothctl

您将收到一个新的提示，您应该输入

agent on
default agent

11:BB:3C:44:5E:FF:7G然后，使用要连接的设备的MAC 地址（一长串以冒号分隔的字母数字字符，类似于）（您应该能够通过devices在此提示符下输入来找到它），运行

trust <MAC>
pair <MAC>
connect <MAC>

答案3

我使用的是 Linux Mint。我尝试了很多解决方案，但我发现最好的一个这里。

我做了什么：

  • 编辑：

    sudo -e /etc/pulse/default.pa

  • 添加了这一行：

    load-module module-bluez5-discover

  • 保存并退出文件，然后使用以下命令重新启动服务：

    sudo systemctl restart bluetooth

答案4

对我有用的解决方案

首先运行此命令

 `sudo install -m 700 -d /var/lib/bluetooth

然后

sudo systemctl start bluetooth

并重启蓝牙服务

sudo systemctl restart bluetooth.service

最后启用蓝牙

`sudo systemctl enable --now bluetooth`

重新启动你的机器，它就会工作
