583578 V. Description of the invention (1) " " The present invention relates to a coordination method of a built-in Bluetooth module, especially to establish a coordination program in a monitor keyboard module to coordinate Bluetooth keys | The wireless keyboard control equations and Bluetooth module function (HCI, Host Controller Interface) processing procedures are internal and compatible with traditional computer keyboard functions. It is known that in the standard Bluetooth module (as shown in Figure 5), the specification mentions three specified electrical interface standards, namely RS-2 32, UART and USB. The protocol application interface between the Bluetooth module and the application host is communicated through hCI (Host Controller Interface). Since the Bluetooth-now standard 'does not provide a keyboard part, the Bluetooth module is directly plugged into the universal serial bus (USB) socket on the host side of the personal computer, because the Bluetooth universal serial bus ( USB) does not have a USB HID (Human Interface Device) keyboard function, so the basic input and input system (BI 0S) inside the personal computer cannot directly use the Bluetooth module. In the current Bluetooth wireless keyboard application, there is no standardization requirement, so as long as it is extended to the original standard, the Cable Replacement Protocol (RFC0MM) specified by the standard is used, plus the HID specified by the USB standard ( Human Interface Dev ice) keyboard standard, and then by an embedded microcontroller. The disadvantage is that the Bluetooth module is a wireless data transmission medium. In the future, the operating system will not be able to directly control the HC I part, because this part has been communicated with the PC by the keyboard receiving end. SB microcontroller Truncation; 爰 Yes, the main purpose of the present invention is to solve the above-mentioned defects in the use of the traditional Bluetooth module, and to avoid the existence of the defects. The invention is built in the Bluetooth keyboard module.
