Implementation process of Android 6.0 Bluetooth communication for Android adaptation

• Android

Note in advance: Android Bluetooth needs to locate the permission application. It can only be used after the user manually confirms the permission in Android 6.0. You can query the data yourself. If it's troublesome, you can use the tool class integrated by the third-party bmob. See the details http://blog.csdn.net/qq_30379689/article/details/52223244 @H_ 301_ 4@
