摘要
目前,基于蓝牙的手机和计算机文本信息传输,尤其是大文件传输存在着严重的传输不稳定的问题。针对这一问题,本文在分析了蓝牙底层协议基础上,采用了BlueSoleil SDK,提出了一种基于FTP的文件传输方法,设计了蓝牙大文件重传机制,解决了蓝牙传输大文件效率不稳定问题。实验结果表明,相比于直接调用Obex协议,采用BlueSoleil + FTP这种方法传输速度提高了1倍,达到141.51 k/s。
At present,there is a serious instability problem in Bluetooth-based text information transmission for mobile phones and computers,especially in the large file transmission.In order to solve this problem,after the analysis of Bluetooth underlying protocol,by adopting BlueSoleil SDK,this paper proposed a file transfer method based on FTP,and designed a large file transmission mechanism based on Bluetooth to solve the problem of instability of large file transmission efficiency.The experimental results show that compared with the method by calling Obex protocol directly,the transmission speed of the proposed method based on BlueSoleil+FTP can increase by one time,reaching a speed of 141.51 k/s.
