specific Embodiment approach 1

[0024] Specific implementation mode one: the following combination figure 1 , figure 2 This embodiment will be described. The framework method of the Bluetooth wireless communication system, the device used in the method is composed of a Bluetooth upper computer 1 and N Bluetooth lower computers 2, and the Bluetooth upper computer 1 is composed of an upper computer 1-1 and an upper computer Bluetooth module 1-2 , the data input and output terminals of the upper computer Bluetooth module 1-2 are connected with the data input and output terminals of the upper computer 1-1, and the Bluetooth lower computer 2 includes the lower computer Bluetooth module 2-1, FPGA2-2 and functional equipment 2- 3. The upper computer Bluetooth module 1-2 establishes a wireless connection with the lower computer Bluetooth module 2-1, and the Bluetooth data output terminal and input terminal of the lower computer Bluetooth module 2-1 are respectively connected to the Bluetooth data input terminal an...

specific Embodiment approach 2

[0044] Specific embodiment two: the difference between this embodiment and the framework method of the Bluetooth wireless communication system described in specific embodiment one is that the bluetooth module 1-2 of the upper computer adopts the model bluecore01~bluecore04 produced by CSR company. The USB interface of the Bluetooth chip is realized by the Bluetooth adapter.

specific Embodiment approach 3

[0045] Specific embodiment three: the difference between this embodiment and the structure method of the Bluetooth wireless communication system described in specific embodiment one is that the lower computer Bluetooth module 2-1 adopts the BTM0304C1H 100-meter Bluetooth with UART interface produced by Jinou Company module implementation.

[0046] The UART (Universal Asynchronous Receiver / Transmitter), namely Universal Asynchronous Receiver / Transmitter, is a serial data bus for asynchronous communication.

Abstract

The invention relates to a Bluetooth wireless communication system architecting method, belonging to the wireless communication field, aiming at solving the problems that a plurality of Bluetooth devices can not be architected into a system and effective communication between one Bluetooth upper computer and a plurality of Bluetooth lower computers can not be realized in the existing wireless communication technology. The method of the invention includes: 1, an upper computer Bluetooth module handle is acquired; 2, handle acquiring condition is judged; 3, an upper computer Bluetooth module is initialized; 4, initialization situation is judged; 5, a Bluetooth lower computer in upper computer Bluetooth module data coverage is searched; 6, connection is established between the Bluetooth upper computer and the selected M Bluetooth lower computers to architect a system, and M connection handles are obtained; 7, system architecting condition is judged; 8, data communication between upper computer and functional equipment is realized; 9, disconnecting is carried out and the handle is released. The invention architects a plurality of Bluetooth devices into a system, realizes effective communication between one Bluetooth upper computer and a plurality of Bluetooth lower computers and is used for Bluetooth wireless communication.

Description

technical field [0001] The invention relates to a frame method of a wireless communication system, which belongs to the field of wireless communication. Background technique [0002] Bluetooth (Bluetooth) is a short-range wireless communication technology, which is used to replace the cable connection between digital devices and computer peripherals and to realize wireless networking between digital devices. [0003] Due to its small size and low power consumption, the Bluetooth module can be easily integrated into most digital devices and has a wide range of applications, including mobile phones, PDAs, notebook computers, printers and digital cameras. With the increasing demand for the mobility and flexibility of digital devices, and the strong support and promotion of many top communication and computer manufacturers in the world, various Bluetooth products and Bluetooth technologies have gradually come out and been improved. my country has outstanding performance in the ...
