| Bluetooth is a wireless connection technology to transmit data and audio signal within a limited range . Bluetooth SIG defines various application profiles. All the application supporting the audio transmission recommend the Headset profile, which has been widely used in both of stationary telephones and mobile telephones. In this thesis, the core technology of Bluetooth is described. Furthermore, the detailed design scheme of the software and hardware of the Headset is presented based on the Bluetooth 1.1 protocol. In the hardware design. SoC (System on Chip)is employed, where the embedded system is the core, integrating the software and hardware as well. Its aim is to pursue the largest capacity. SoC focuses RF receiving and sending cell, base frequency celL microprocessor and flash etc. All of them play a key role in Bluetooth communications. Correspondingly, the software design adopts the embedded method, hi this way. all protocols are downloaded into flash which is outside the kernel processor of Bluetooth device. Through human-machine interface, operation comes true, hi the end . my work is generalized and a preview of the prospect in the field of Bluetooth technology is given. |
