Problems solved by technology

However, because some Bluetooth devices are relatively small, or do not have an interface for inputting numbers or letters, such as Bluetooth mice, Bluetooth printers, etc., it is not necessary to add an input interface to support the above-mentioned pairing and authentication procedures of free input of PIN code. , resulting in additional cost burden; it is unable to obtain Link Key and generate Encryption Key, and cannot support encryption
[0005] In addition, wireless online pairing authentication often causes problems with online devices due to the presence of similar devices in the same area

Abstract

A method and a system for finishing blue teeth on-line pair program, in which, the system includes at least two blue teeth devices and a central control device. These blue teeth equipments are connected with the central control device in wire which searches for information of the equipments to all blue teeth equipments, such as their address(BD-ADDR), varieties and on-line mode and judges the possible formed on-line pairs from the information and generates a link key for each pair, finally, it writes information of link key and each object into each blue tooth equipment.

Description

technical field [0001] The invention relates to a bluetooth (bluetooth) online pairing (pairing) program. In particular, the invention relates to a method and a system for completing the bluetooth pairing procedure through a wired connection. Background technique [0002] Bluetooth technology is a wireless transmission technology that enables short-distance communication between desktop and laptop computers, personal digital assistants (PDAs), mobile phones, printers, scanners, digital cameras, and even home appliances. wireless connection. The principle of Bluetooth technology is to use the frequency of the ISM band (about 2.4-2.48GHz) to transmit data and voice wirelessly. Every device with Bluetooth technology has a standard address, which is the Bluetooth device address (BD_ADDR), which allows you to use low-power radios for one-to-one to at most one-to-seven (forming a small network) connection, The transmission range can reach up to 10 meters. Bluetooth technology ...
