Bluetooth connection method and system

Abstract

The invention provides a Bluetooth connection method. The method comprises the following steps of: reading information stored in radio frequency identification (RFID) card by using a client; and according to the read information, establishing Bluetooth connection with a service end. The invention also provides a Bluetooth connection system. The Bluetooth connection system fulfills the aim of automatically finishing the Bluetooth identification when performing Bluetooth service discovery by pre-storing a Bluetooth address and an identification (ID) value of the RFID card in the RFID card and performing interaction with the service end by directly using a service discovery protocol (SDP) after the client reads the information stored in the RFID card, thereby establishing safe and reliable Bluetooth connection. The method greatly reduces Bluetooth connection establishing time, so that the application of a Bluetooth service is more concise and quicker to realize and convenient to popularize, and has lower cost and higher efficiency.

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.
