Bluetooth wireless communication replaces cables and realizes communication between computers, PDAs (Personal Digital Assistants, Personal Digital Assistants), phones and peripherals. Wireless connections. For example, Bluetooth devices can now be used to connect mobile phones and hands-free headsets. Since its inception, Bluetooth technology has given us a higher purpose, allowing us to create "Personal Area Networks (PAN)" or "piconets".

The Bluetooth specification includes two files, the core protocol (Core) and the application framework (Profiles). The protocol specification part defines the various layers of Bluetooth communication protocols, and the application framework points out how to use these protocols to realize specific application products. The Bluetooth protocol specification follows the Open System Interconnection/Referenced Model (OSI/RM), which defines each level of the Bluetooth protocol stack from low to high.

Bluetooth interconnection requires binding authentication, which limits the users who communicate with each other to friends who know each other, and the mutual binding between strangers is often rejected due to reasons such as distrust and unknown binding passwords. This makes the use of the Bluetooth function in the mobile phone limited to the range of acquainted users, greatly weakens the use value of Bluetooth, and ignores the application of new functions in a wider range.

At present, some methods are used to solve this problem, such as pairing communication by adding a radio frequency pairing module; or binding by leading out contact points and quickly transmitting information through contacts. These methods have their own advantages and disadvantages, but the most direct disadvantage is the increase of hardware cost and the difficulty of software implementation.

If there is a method between strangers in relatively fixed areas such as buses and subways, if there is a way to establish Bluetooth binding between strangers, with the information of the active sender (personal data, purpose, shared resources, Binding password, etc.), and this information can be edited and generated by the sender user, then the possibility of establishing Bluetooth communication between strangers is greatly increased, which is convenient for users to make friends, share resources, etc., thereby improving the utilization rate of mobile phone Bluetooth and improving The user experience effect will provide users with a brand-new communication method without increasing the cost of generation.
