AI Technical Summary

Benefits of technology

This patented technology allows finding things like mobile phones or smartphones without their ability to connect through wireless networks (Bluetooth). It uses an identifier from your phone's own memory to determine its approximate proximity based on how far away they are located. If there were no nearby BLU connected to them, then these connections would also work properly.

Problems solved by technology

The technical problem addressed in this patented solution relates to finding things like earbuds without their use on cellular telecommunications systems (cell) due to lack of an answer keypad at handset receivers.

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.
