Abstract

Based on researching of Bluetooth Protocol, a kind of Bluetooth data transferring system based on MCU-controllinghas been proposed in the paper. In the system, the MCU in which the Bluetooth HCI protocol has been embedded is used to control the Bluetooth module on UART and make the Bluetooth devices in the Bluetooth network establish connection and transfer data automatically. In the hardware design, the chip C8051F020 is selected as the host controller. Because chip C8051F020 has two UART serial interfaces, it can meet the requirement of design, simplify the circuit and enhance system anti-jamming capability. The Bluetooth module used in the system is CSR Bluetooth Core 4 with Bluetooth Standard 2.0 class 1 which has the advantages of high signal sensitivity, long distance of connection and easy to use..
