| Bluetooth, as a wireless data and voice communications technology, has high reliability, low power consumption, convenient usage, and other fine features, which has got the industry's attention. Embedded systems is combination of the advanced computer, semiconductor and electronic technology and specific applications in various industries, which is a technology-intensive, highly decentralized and innovative knowledge integration system.Bluetooth technology gradually penetrated into the current embedded systems, and the latter supports for Bluetooth development. The trail of Bluetooth can be found in Notebook computers, mobile phones, handheld PAD and automobile. As technology advances, Bluetooth technology will go into the scanner, digital camera, and more hardware devices in the future, therefore the study of embedded systems and the combination of Bluetooth technology is significant.The paper mainly discusses the ARM9-based microprocessor architecture 2440 platform embedded Bluetooth technology and Bluetooth File Transfer Platform application development. First the paper introduces the embedded Linux cross-compiler build environment, embedded Linux system configuration, building and migration process; secondly, the paper illustrates the porting process of Bluez Bluetooth protocol stack based on S3C2440 development board and builds an embedded Bluetooth application development Platform, and finally the paper finishes Bluetooth wireless file transfer systems on this platform.The results show that the embedded system based on Bluetooth system is stable, and it can be achieved multi-media format file transfer within a small scope. It provides reference for the development of Bluetooth-based embedded systems. |
