当我点击“设置”中的开关按钮时，它并没有打开，尽管按钮看起来像是打开的。下面仍然显示“蓝牙已关闭”。我打开了耳机，看看它们是否能够连接，但什么也没发生。
尝试过sudo apt update && sudo apt upgrade，但是没有效果。

我尝试运行sudo dmesg但确实收到一些错误：
[ 24.237131] Bluetooth: hci0: BCM: firmware Patch file not found, tried:

[ 26.252959] Bluetooth: hci0: Opcode 0x1003 failed: -110
看来我缺少一些固件。我不确定应该从哪里获取它。
当我运行bluetoothctl然后尝试时power on，scan on它们都返回“没有可用的默认控制器”
