连接蓝牙鼠标

连接蓝牙鼠标

我两天前刚买的鼠标有问题。它是 Logitech MX anywhere 2。我曾经可以连接它并能够配对,但现在我无法再连接它了。你们有人有解决方案吗?

答案1

我认为它已被 阻止rfkill。请尝试使用此命令来解除阻止。

rfkill unblock bluetooth

如果成功,则查看/etc/default/tlp文件。很可能是 TLP 阻止了蓝牙。应该有一行这样的内容

DEVICES_TO_DISABLE_ON_STARTUP="wifi bluetooth"

编辑文件并bluetooth从中删除。然后蓝牙将在启动时可用。

另请确保已启用所有硬件开关。

答案2

仅有的当你有传输层协议已安装:

尝试将你的内部 USB 蓝牙适配器从省电模式中排除(列入黑名单) --> 参见TLP 常见问题解答
