Abstract

Enhance Data Rate (EDR) in Bluetooth 2.0 specifications provide condition for Bluetooth multi-point communication. Aiming at application requirements of Bluetooth technique in wireless communication, Embedded Bluetooth Information Broadcast System (EBIBS) based on ARM9 microprocessor S3C2440 was designed and implemented. The system runs on ARM-Linux operation system and achieves single point transmission, multi-point transmission and information update based on Bluetooth 2.0 specifications. BlueZ protocol stacks and object exchange (OBEX) were utilized to complete multi-point transmission. Device driver technique was used to switch core functions and retransmission mechanism to ensure reliability of information broadcast. The system has been verified at broad-level and practical application. The result was also provided.
