加载 hci0 的 LTK 超时

Question

由于hci0 加载 LTK 超时，我无法使用\nbluetoothctl 命令连接到蓝牙。

从rfkill命令我们可以说蓝牙设备没有被阻止？

\n

$ rfkill list\n0: hci0: Bluetooth\n    Soft blocked: no\n    Hard blocked: no\n1: phy0: Wireless LAN\n    Soft blocked: no\n    Hard blocked: no\n

用于连接到我的airpods的Bluetoothctl命令。我已经通过蓝牙停止并重新启动了好几次，但仍然无法连接到我的airpods。

\n

$ bluetoothctl connect BB:91:C0:4E:22:EF\nAttempting to connect to BB:91:C0:4E:22:EF\nFailed to connect: org.bluez.Error.NotReady\n
