我刚刚收到一台新的 HP 设备。
默认情况下，重新启动后，蓝牙服务无法正确启动，找不到任何可配对的设备，NetworkManager 的蓝牙指示灯也从“关闭”状态变为“打开”状态。
设备：
Bus 002 Device 002: ID 8087:0029 Intel Corp. AX200 Bluetooth
日志表明 rfkill 存在问题：
22:22:46 bluetoothd: Failed to set mode: Blocked through rfkill (0x12)
22:22:46 bluetoothd: Failed to set mode: Blocked through rfkill (0x12)
22:19:44 bluetoothd: Failed to set mode: Blocked through rfkill (0x12)
22:13:44 bluetoothd: Failed to set mode: Blocked through rfkill (0x12)
22:13:43 bluetoothd: Failed to set mode: Blocked through rfkill (0x12)
事实上，它是“软阻止”：
# rfkill list
0: hci0: Bluetooth
Soft blocked: yes
Hard …
