> 初始化
```java

//初始化UniversalBluetoothLE
universalBluetoothLE = UniversalBluetoothLE.inistance(MainActivity.this);
```
> 检测是否打开蓝牙并且请求系统打开蓝牙
```java
//检测是否打开蓝牙并且请求系统打开蓝牙
universalBluetoothLE.openBbletooth();
```
> 链接设备
```java
mBluetoothGatt=universalBluetoothLE.getConnectGatt(device,true,mGattCallback);
mBluetoothGatt.connect();
```
