Abstract

The invention discloses a positioning method and a positioning device based on Bluetooth. The method comprises the following steps of: transmitting a power setting instruction to target Bluetooth equipment, wherein the power corresponding to the instruction reduces gradually; obtaining a power threshold value when the target Bluetooth equipment is out of connection; and matching a preset communication distance mapping table according to the power threshold value, if matching, taking the corresponding distance value as the communication distance corresponding to the target Bluetooth equipment. By obtaining the communication distance from the target Bluetooth equipment, the identification error range of the position of the Bluetooth equipment is greatly reduced and the positioning precision is effectively improved.

Description

Technical field [0001] The invention relates to the field of radio technology, in particular to a Bluetooth-based positioning method and device. Background technique [0002] In real life, we often encounter the difficulty of finding small items or equipment. For example, earphones and mobile phones are left in a corner, and because they have not been used for a period of time, and the user has forgotten the location, they cannot be found for a while when they are urgently needed. [0003] In response to the above problems, for a mobile phone with a call function and a speaker, the user can dial the mobile phone and determine the location by sound. However, the above positioning method cannot be implemented for devices such as headphones that do not have a called function and a speaker. [0004] Therefore, how to locate the Bluetooth device quickly and accurately has become a technical problem urgently needed to be solved by those skilled in the art. Summary of the invention [000...
