蓝牙问题 - 每 2~3 秒连续打开/关闭？

  • 772

Ubuntu 版本：18.04 内核：4.15.0-45-generic

我不知道原因，但突然蓝牙在我的 ubuntu 机器上不起作用。正如您看到的系统日志，它无限重复。它每1~2秒发生一次。现在很疯狂。

上周运行良好。但是今天我意识到它现在有问题。

任何人都可以帮忙吗？

  1. Best Answer

    在我进行了一些更改以与 PS3 操纵杆配对后，我解决了蓝牙中类似问题的问题， 根本无法正常工作

    • 只需关闭系统：sudo shutdown -h now
    • 拔下所有连接的电缆，例如电源、HDMI、CAT5.E，甚至键盘和鼠标 USB
    • 几秒钟后，再次插入，最终成功了

    我回答谁遇到类似问题的问题

  2. 我通过将内核更新到最新版本（4.19 到 5.9）、关闭、拔下所有 USB 设备、重新启动并一一插入设备来解决了这个问题。
