整理了 Android藍牙2.0SSP和4.0 BLE 所有示例apk及源碼下載及視頻保證能收發十六進制或字符有自動連接已經配對的設備手機與串口模塊通信等,未公佈的源碼100一份。

注意：20190507關於android 6.0及後續系統搜不到藍牙SSP2.0設備模塊的原因及解決

在6.0版本前，使用藍牙功能，只需要配置下面的權限即可：

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

6.0及後續版本，使用藍牙掃描，還需要添加如下的權限，且該權限還需要在使用時動態申請：

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

或

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

所以要使用藍牙SSP2.0設備模塊，總共要3條權限：

<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提示允許打開藍牙和定位權限時，不要拒絕）
