Taking the advantage of NFC technology's features of highly safe, convenient and low power dissipated when exchanging data, we present two schemes of using NFC to establish the Bluetooth connection. They combine the transmission of NFC and of Bluetooth together so avoid complex operations the traditional Bluetooth transmission process do in devices searching, matching and so on, and meanwhile ensure the security of data transmission. This has solved the problems of Bluetooth transmission including being complicated in connection process, high power dissipation and poor security, etc. The "NFC + Bluetooth" data transmission system is designed and implemented according to one of the schemes, it has good test performance, its overall performance is superior to traditional Bluetooth transmission. The results show that to apply this scheme in data transmission between mobile devices has high availability.%利用NFC技术交换数据安全性高、便捷、功耗低等特点,提出使用NFC为 蓝牙建立连接的两种方案,把NFC与蓝牙传输结合起来,避免传统蓝牙传输连接过程搜索设备、配对等繁杂操作,同时保证数据传输安全性,解决了蓝牙传输连接过程复杂、设备功耗大、传输安全性较差等问题.根据其中一种方案设计并实现了“NFC+蓝牙”数据传输系统,测试性能良好,总体性能优于传统蓝牙传输方式,结果表明采用该方案用于移动设备间数据传输具有较高可用性.
