我从github下载了1.5.0-rxjava2版本。在清单文件中添加了以下内容：
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
在我的手机上构建并运行应用程序，授予其位置权限，但是当我开始扫描蓝牙设备时，它没有显示任何内容，显示为here。
周围有各种各样的设备，我尝试使用谷歌的我的应用程序，它显示不同的设备。
我需要在示例rxAndroidBle应用中做些什么才能显示出设备？
更新logcat输出：
