根据我的经验，蓝牙 HCI 监听功能需要您的设备获得 root 权限.在我有 root 权限的 Samsung Galaxy S GT-I9000 上它工作正常，而在我非 root 用户的 Galaxy S3 Neo 上此功能不起作用.

According to my experience the Bluetooth HCI snooping feature requires your device to be rooted. On my rooted Samsung Galaxy S GT-I9000 it works fine while on my non-rooted Galaxy S3 Neo this feature does not work.

此外，您应该确保您没有意外删除该文件.每当我删除文件时，我都必须重新启用蓝牙监听功能，以便系统重新创建日志文件.

Moreover, you should make sure that you have not accidently deleted the file. Whenever I delete the file I have to re-enable the Bluetooth snooping feature in order to make the system recreate the log file.
