Abstract

The invention provides a Bluetooth warning device and communication equipment. After establishment of Bluetooth pairing and connection of the Bluetooth warning device and the communication equipment, the Bluetooth warning device continuously sends out a first Bluetooth signal, and the communication equipment continuously sends out a second Bluetooth signal. The Bluetooth warning device calculates a received signal strength indication (RSSI) value of the received second Bluetooth signal, and judges whether the RSSI value exceeds a preset threshold value. When the RSSI value exceeds the preset threshold value, the Bluetooth warning device raises an alarm through an alarm. The communication equipment calculates a RSSI value of the received first Bluetooth signal and judges whether the RSSI value exceeds a preset threshold value. If the RSSI value exceeds the preset threshold value, the communication equipment sends out a warning signal through an output device. The invention further provides a warning method.

Description

technical field [0001] The invention relates to a warning device, in particular to a bluetooth warning device and method. Background technique [0002] In daily life, people and things are often lost. For example, due to the temporary negligence of the guardian, the elderly or young children may get lost or be abducted by bad guys when they go out. The handbag or backpack you carry when you go shopping may also be forgotten in a certain place or stolen by thieves due to the momentary focus on other things (such as shopping for goods, answering the phone).
