蓝牙服务设置模式失败

因此，我尝试使用我的无线耳机，但发现 Ubuntu 21.04 有一个错误：


● bluetooth.service - Bluetooth service
     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2021-05-26 07:40:51 MSK; 53min ago

我该如何修复它？

答案1

它对我有用

sudo rfkill unblock bluetooth
sudo systemctl stop bluetooth
sudo systemctl status bluetooth
sudo systemctl restart bluetooth

答案2

这提到的答案与hciconfig来自bluez 包在 Ubuntu 22.04 上工作。具有 root 权限：

hciconfig hci0 down  # Close HCI device.
rmmod btusb          # Remove btusb module from the kernel
modprobe btusb       # Add it back
hciconfig hci0 up    # Open and initialize HCI device

一行

hciconfig hci0 down && rmmod btusb && modprobe btusb && hciconfig hci0 up

如果仍然不起作用，请再次检查拔出/插入，检查是否列出（sudo hciconfig -a）以及是否没有被阻止（sudo rfkill list）。

如果使用 Sony WH-1000XM4，请按住电源按钮直到启用配对模式，大约 6 秒钟。
