Bluetooth connection method and system

Abstract

The present disclosure provides a Bluetooth connection method, the method includes that: a client reads information stored in a Radio Frequency Identification (RFID) card and establishes a Bluetooth connection with a server according to the read information. The present disclosure also provides a Bluetooth connection system, wherein a Bluetooth address and an identification (ID) value of the RFID card are pre-stored in the RFID card; after reading the information stored in the RFID card, the client directly uses a Service Discovery Protocol (SDP) service search to carry out an interaction with the server, achieving automatic completion of a Bluetooth authentication while a Bluetooth service search is performed, thereby establishing a secure and reliable Bluetooth connection; The method significantly reduces the time for establishing a Bluetooth connection, and makes the application of the Bluetooth service more concise and rapid to realize, costing less, more efficient, and easier to popularize.

Description

technical field [0001] The invention relates to the bluetooth technology of wireless communication, in particular to a bluetooth connection method and system. Background technique [0002] Bluetooth (Bluetooth) is a radio technology that supports short-distance communication of devices. The general communication distance is within 10m. exchange. The use of Bluetooth technology can effectively simplify the communication between mobile communication terminal equipment, and can also successfully simplify the communication between equipment and the Internet, so that data transmission becomes more rapid and efficient, and broadens the road for wireless communication. [0003] Bluetooth adopts distributed network structure, fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint communication, works in the global 2.4GHz ISM (Industrial Scientific Medical) frequency band, and its data rate is 1Mbps, using time division duplex The transm...

AI Technical Summary

Problems solved by technology

However, the currently commonly used Bluetooth connection mode has a shortcoming, that is, before establishing a Bluetooth connection, it is necessary to query the Bluetooth device and query service, and it will take more than ten seconds or even 20 or 30 seconds to complete the above query; not only In this way, the above query also requires human participation

Therefore, the currently commonly used Bluetooth connection mode cannot well meet the requirements of simple and fast connection in communication terminals and constantly changing environments.
