我想通过蓝牙将文件从手机发送到笔记本电脑,反之亦然。但是我系统上的蓝牙不起作用。当我在“ 系统设置”>“蓝牙”中打开蓝牙开关时,什么也没发生,而且右侧的可见性开关始终处于禁用状态。
输出rfkill list
如下:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: hp-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
输出dmesg | grep Blue
如下:
[ 29.519992] Bluetooth: Core ver 2.21
[ 29.520012] Bluetooth: HCI device and connection manager initialized
[ 29.520016] Bluetooth: HCI socket layer initialized

我不知道是否安装了驱动程序,也不知道如何检查。
知道是什么问题吗?
