当我运行时bluetoothctl
出现错误,
$ bluetoothctl scan on
No default controller available
但内核显示设备已加载,
bluetooth hci0: firmware: direct-loading firmware intel/ibt-19-0-1.sfi
答案1
您要做的是安装rfkill
和取消阻止蓝牙:
sudo apt install rfkill
然后
$ sudo rfkill
ID TYPE DEVICE SOFT HARD
0 bluetooth tpacpi_bluetooth_sw blocked unblocked
2 wlan phy0 unblocked unblocked
可以看到id0
被屏蔽了
$ sudo rfkill unblock 0
如果您结账时仍然遇到错误这个问题
