蓝牙通过rfkill阻塞

Question

rfkill列表1

命令给我：

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

但是，当我运行以下命令时，

systemctl状态bluetooth.service

我知道这个错误：

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Ubuntu18.04.1 LTS。当我启动蓝牙时，它会搜索设备，但它从未完成。

Answer 1

我目前在X1 Carbon ThinkPad上的薄荷19.3 (内核5.4.0-48-泛型)中有这个问题。我的rfkill显示蓝牙是很难阻断的。不知道为什么有必要这样做，但它对我有效：

sudo rfkill unblock bluetooth

在过去的两周里，我不得不做了两次，这意味着一些随机的事情正在发生，导致蓝牙在重启后被阻塞。随意的问题总是令人讨厌的。

Answer 2

我也有同样的问题：rfkill没有显示设备被阻塞，而是显示命令

# rfkill block bluetooth
# rfkill unblock bluetooth

为我工作过。

希望我能帮上忙
