Problems solved by technology

On the other hand, when there are many peripheral devices around, since there are only three channels for broadcasting, if all peripheral devices continuously send out broadcast information at the same time, it is possible to be on the same channel at the same time. Two or more broadcast information overlap, which is difficult to be detected by the central device
In addition, because the broadcast information is continuously sent, the broadcast information of the same peripheral device may be repeatedly detected multiple times
These factors will lead to longer roll call time and lower efficiency of roll call processing

Abstract

The invention provides a low-power-consumption bluetooth roll call system which can cope with a large number of roll call objects and efficiently performs roll calling. The low-power-consumption bluetooth roll call system comprises a center device capable of performing roll calling of peripheral devices and a plurality of peripheral devices capable of being connected with the center device throughlow-power-consumption bluetooth. After the center device detects the roll call objects and stores the roll call data of the roll call completion devices, the center device establishes bluetooth connection with the roll call completion devices and transmits an instruction to stop broadcasting within the required time to the roll call completion devices. When the roll call completion devices receive the instruction, the roll call completion devices stop transmitting broadcast information within the required time.

Description

technical field [0001] The invention relates to a low-power bluetooth calling system realized based on low-power bluetooth communication. Background technique [0002] In recent years, with the development of the Internet of Things technology, wireless communication methods based on wireless LAN, Bluetooth (Bluetooth), and Bluetooth Low Energy (Bluetooth Low Energy, BLE) have been widely popularized. Compared with traditional Bluetooth, Bluetooth low energy technology is designed as an ultra-low power (ULP) wireless technology, which minimizes power consumption and has features such as fast connection. [0003] A Bluetooth low energy system usually consists of a central device and peripheral devices. In the case of peripheral device detection, the peripheral device is set to broadcast mode and repeatedly sends broadcast information to the surroundings, and at the same time, the central device is set to scan mode, in which it can receive broadcasts sent from peripheral devic...
