通过 rfkill 阻止蓝牙

Question

rfkill 列表 1

命令给了我：

1: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no

但是，当我运行以下命令时，

须藤 systemctl 状态 bluetooth.service

我收到此错误：

bluetooth.service - Bluetooth service
 Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
   Active: active (running) since Sun 2019-01-27 13:55:21 +03; 1h 4min ago

我使用 Ubuntu 18.04.1 LTS。当我启动蓝牙时，它会搜索设备，但它永远不会完成。

Answer 1

我目前在 X1 Carbon ThinkPad 上的 Mint 19.3（内核 5.4.0-48-generic）中遇到这个问题。我的rfkill蓝牙显示为硬阻止。不知道为什么需要以下内容，但它对我有用：

sudo rfkill unblock bluetooth

在过去的两周里，我不得不这样做两次，这表明正在发生一些随机的事情，导致蓝牙在重新启动后被阻止。随机问题总是一个热点。

Answer 2

我遇到了同样的问题：rfkill没有显示设备被阻止，而是命令

# rfkill block bluetooth
# rfkill unblock bluetooth

为我工作。

我希望我有帮助
