对coreBluetooth的第三方框架DarkBlue的封装

之前写过一篇关于使用对coreBluetooth的第三方框架一个介绍：《Core Bluetooth ——DarkBlue-master第三方框架》

http://www.cnblogs.com/yuanjunliang/articles/4633726.html

下面是对该第三方具体实现的一个封装

    });

}

#pragma mark - BTServerDelegate
- (void)didDisconnect
{
    [self.defaultBTServer startScan];
}

@end

由于该项目中使用了和本地设备的一个测试连接，具体使用的时候需要根据自己的设备的UUID进行调整
