Research And Development Of OBEX Protocol On Android Bluetooth System

Android smart phone system, and Bluetooth wireless technology is an increasingly wide range of applications in the context of the times of Things. Various functional modules on Android platform and wireless technology have become a hot research today. In this paper, by analyzing the Bluetooth module Bluetooth on Android platform from low-up all the technical details, analyzing Android system functions, and system level Bluetooth file object transmission.The article has researched the object model and the session protocol of OBEX protocol and parsed binding on the file transfer, we describe the steps of Android Bluetooth system in detail and build the Bluetooth application programming platform of OBEX, and achieve a file or folder transfer between Android devices., At the same time more effective expansion of the application to ensure that the next step to resolve the majority of cell phone use RFCOMM protocol file object transmission development cumbersome and costly way to achieve this.We mainly do that: First. The whole framework of the Android platform Bluetooth technology implementations;Second. BlueZ protocol stack use and implementation process of the driver in the Android platform, OBEX protocol and implemented in the Android platform, based on the text object OBEX protocol efficient transmission and other problems,Third. The solutions to these problems, greatly improving the Bluetooth range of applications and application development cycle on the Android platform, are convenient channel for application developers, and improve the vast majority of users promotion of Bluetooth wireless technology on the new generation of smart phones.
