整理了 Android蓝牙2.0SSP和4.0 BLE 所有示例apk及源码下载及视频保证能收发十六进制或字符有自动连接已经配对的设备手机与串口模块通信等,未公布的源码100一份。

注意：20190507关于android 6.0及后续系统搜不到蓝牙SSP2.0设备模块的原因及解决

在6.0版本前，使用蓝牙功能，只需要配置下面的权限即可：

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

6.0及后续版本，使用蓝牙扫描，还需要添加如下的权限，且该权限还需要在使用时动态申请：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>

或

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>

所以要使用蓝牙SSP2.0设备模块，总共要3条权限：

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>

（APP提示允许打开蓝牙和定位权限时，不要拒绝）
