####初始化

bleManager = BleManager.getInstance();

bleManager.init(this);

####扫描指定名称设备、并连接

bleManager.connectDevice(

DEVICE_NAME,

TIME_OUT,

new BleManagerConnectCallback() {

@Override

public void onConnectSuccess(BluetoothGatt gatt, int status) {

Log.i(TAG, "连接成功！");

}

@Override

public void onServicesDiscovered(BluetoothGatt gatt, int status) {

Log.i(TAG, "服务被发现！");

}

@Override

public void onConnectFailure(BleException exception) {

Log.i(TAG, "连接失败或连接中断：" + '\n' + exception.toString());

}

});

####notify

bleManager.notifyDevice(

UUID_SERVICE_LISTEN,

UUID_LISTEN_NOTIFY,

UUID_CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR,

new BleManagerNotifyCallback() {

@Override

public void onNotifyDataChangeSuccess(BluetoothGattCharacteristic characteristic) {

Log.d(TAG, "特征值Notification通知数据回调： "

+ '\n' + Arrays.toString(characteristic.getValue())

+ '\n' + HexUtil.encodeHexStr(characteristic.getValue()));

}

@Override

public void onNotifyDataChangeFailure(BleException exception) {

Log.e(TAG, "特征值Notification通知回调失败: " + '\n' + exception.toString());

}

});

####indicate

bleManager.indicateDevice(

UUID_SERVICE_LISTEN,

UUID_LISTEN_INDICATE,

UUID_CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR,

new BleManagerIndicateCallback() {

@Override

public void onIndicateDataChangeSuccess(BluetoothGattCharacteristic characteristic) {

Log.d(TAG, "特征值Indication通知数据回调： "

+ '\n' + Arrays.toString(characteristic.getValue())

+ '\n' + HexUtil.encodeHexStr(characteristic.getValue()));

}

@Override

public void onIndicateDataChangeFailure(BleException exception) {

Log.e(TAG, "特征值Indication通知回调失败: " + '\n' + exception.toString());

}

});

####写指令

bleManager.writeDevice(

UUID_SERVICE_OPERATE,

UUID_OPERATE_WRITE,

UUID_CLIENT_CHARACTERISTIC_CONFIG_DESCRIPTOR,

HexUtil.hexStringToBytes(SAMPLE_WRITE_DATA),

new BleManagerWriteCallback() {

@Override

public void onDataWriteSuccess(BluetoothGattCharacteristic characteristic) {

Log.d(TAG, "写特征值成功: "

+ '\n' + Arrays.toString(characteristic.getValue())

+ '\n' + HexUtil.encodeHexStr(characteristic.getValue()));

}

@Override

public void onDataWriteFailure(BleException exception) {

Log.e(TAG, "写读特征值失败: " + '\n' + exception.toString());

}

});

####关闭操作

bleManager.closeBluetoothGatt();

####其他

其他蓝牙操作可参考示例代码，或从BleManager这个类中开放的方法中找到。
