Abstract


With the development of communications, networking , and computer technology to the development of traditional control technology has brought a new opportunity . Bluetooth technology is a used for digital hardware devices of a variety of fixed and mobile between a low cost, high efficiency of the wireless communication connection technology, in practical application to replace the cumbersome cable connection . Subject to the British Cambridge SiliconRadio students BlueCoreTM02 Bluetooth chip as the object of study , the Bluetooth 1.2 protocol stack design guidance given based on Bluetooth HID protocol stack serial keyboard and mouse to take the data acquisition scheme . Bluetooth specification is free and open by the Bluetooth SIG developed the Bluetooth technology standard , including the core specification (Core Specification) and Application Specification (Profile) two parts . Core specification defines the work of each of the layers of protocol , and application specification is taken in order to achieve a particular application model specific protocol layer between the operating mechanism. Bluetooth protocol underlying hardware module system can be divided into three parts , intermediate protocol layer and high - end application layer . Link management , baseband layer and RF the layer belonging Bluetooth hardware module . Logical Link Control and Adaptation Protocol , belong to the intermediate protocol layer service discovery protocol , serial port emulation protocol , general software . The high-end application layer is used for a variety of application models the Profile . This thesis analyzes and Bluetooth core protocol , then analyzed based on the realization of the Bluetooth HID high-end application mode , software -based HID protocol HCI, logical link control adaptation protocol and service discovery protocol . Given to serial keyboard and mouse data acquisition hardware and software design , and the HID application specification based on the entire system design combined Bluetooth development tools BBDK, the complete design process for the keyboard and mouse -based HID specification . In the collection end of the scan code as a Bluetooth host microprocessor to achieve the HID high-level application specification , the Bluetooth host C language based on the HID protocol HCl , L2CAP, SDP ; Bluetooth host PC, as the PC end , the VC C class encapsulates the 6.0 environment to achieve the above-mentioned agreements .
