基于Android移动端的应用程序与蓝牙模块间数据通信研究

Research on Data Communication between Application Program and Bluetooth Module Based on Android Mobile Terminal

无线传输数据方式的发展代替了早期的串口通信,它包括点对点传输、蓝牙、Wi-Fi等。本文主要介绍蓝牙这种无线连接方式、蓝牙传输过程中存在的问题以及解决方法。一个蓝牙模块中集成了蓝牙芯片,能够在近距离内发送接收无线电信号,故能够起到信息传输的作用。这是较好的信息交流方式,它凭借功耗低、设备成本低、传输距离近的优点在数据传输中得到了广泛的应用。本文对于Android移动端的应用程序与蓝牙模块间数据通信传输进行研究,寻找一种简单便捷安全的通信方式。

The development of wireless data transmission has replaced the early serial communication,which includes point-topoint transmission,Bluetooth,Wi-Fi and so on. This paper mainly introduces Bluetooth,the wireless connection mode,the problems in the process of Bluetooth transmission and the solutions. Bluetooth chip is integrated in a Bluetooth module,which can send and receive radio signals in close range,so it can play the role of information transmission. This is a better way of information exchange. It has been widely used in data transmission because of its low power consumption,low equipment cost and close transmission distance. This paper studies the data communication transmission between the application program of Android mobile terminal and Bluetooth module,looking for a simple,convenient and secure communication mode.
