Embodiment Construction

[0024] figure 1 is the system block diagram of this Bluetooth USB adapter. like figure 1 As shown, the Bluetooth USB adapter 100 is composed of several functional modules. Wherein, the USB interface 110 provides the required USB interface function to be connected with the computer, and the required data is provided by the HID (Human-Computer Interaction Device) protocol module 160 in the startup mode, and is provided by the HCI (Host Control Interface) in the normal mode 120. ) The controller 130 provides. The standard communication protocol L2CAP (Logical Link Control and Adaptation Protocol) 170 multiplexes various protocols of the upper layer. The link manager 180 is responsible for receiving commands and data sent by the upper layer modules, and returning the results to the upper layer. The link manager 180 completes corresponding functions through the baseband controller 190 and the wireless transceiver 150 . The link management protocol 140 is used for mutual commun...

Abstract

A method for making bluetooth USB adapter have the man-machine interaction function (HID) is disclosed. With said method, a bluetooth USB adapter and a bluetooth keyboard or mouse can cooperate to implement an ordinary USB keyboard or mouse when compute is started. If the BIOS of computer does not support bluetooth function, the method can make user use bluetooth keyboard and mouse on starting.

Description

technical field [0001] The invention relates to bluetooth and USB technologies in the field of wireless communication, in particular to a human-computer interaction method. Background technique [0002] Bluetooth (Bluetooth) is a short-range wireless communication technology that works in the 2.4GHz ISM (Industrial-Scientific-Medical) frequency band. The basic network structure of Bluetooth is a piconet (Piconet) composed of a master device and up to seven slave devices. The master device and slave devices communicate by means of time division multiple access (TDMA). Using Bluetooth technology, various devices can be connected in a low-cost manner. [0003] USB (Universal Serial Bus) technology is a standardized wired connection method for interconnection between computers and peripherals, and it supports the connection between computers and various peripherals. The main features of the USB interface are: plug and play, hot-swappable. As long as the user simply inserts th...
