这个日志并没有明确指出蓝牙无法扫描到其他设备的原因。但是可以从中看出一些信息:
1. `requestAudioFocus()` 表示某个应用程序正在请求音频焦点,这可能会导致蓝牙无法正常工作。
2. `Could not find remote control icon properties` 可能是由于蓝牙设备不支持某些功能导致的。
3. `blueToothChange:关闭` 表示蓝牙已关闭,可能是用户手动关闭或者其他原因导致的。
因此,你需要检查以下几个方面以解决问题:
1. 检查是否有其他应用程序正在请求音频焦点,如果有,请关闭它们并重新启动蓝牙。
2. 检查蓝牙设备是否支持您想要使用的功能。如果不支持,请尝试使用其他设备或更改功能设置。
3. 检查蓝牙是否已经被关闭。如果是,请打开蓝牙并重新连接设备。如果不是,请检查蓝牙连接是否正常,或者重启设备。

此日志中记录了一个蓝牙打印相关的应用程序的运行过程。在这个应用程序中,MainActivity被创建并且sendBroadcast()方法被调用以发送广播。然后,系统收到了这个广播并且将其发送到了一个非保护的广播中,可能会被其他应用程序接收到。MediaPlayerFactory创建了一个新的MediaPlayer实例,同时MediaPlayerNative记录了一些信息和警告。BluetoothService状态被设置为true并且HiMW_TVClient执行了一些操作。最后,AudioManager请求了音频焦点并且BluetoothAdapter被启用。
