A non-pairing fast data transfer method for Bluetooth low energy devices

Abstract

The invention provides a non-paired fast data transmission method applied to a low power consumption Bluetooth device. The non-paired fast data transmission method applied to a low power consumption Bluetooth device is characterized by comprising the following steps: 1) setting a unique identification code for each acquisition or measurement object, and setting a numeric encoding corresponding to the MAC address for each Bluetooth acquisition or measurement slave device; 2) arranging a Bluetooth master device in the area where the acquisition or measurement object located in, wherein the Bluetooth master device adopts the non battery power supply mode; after the electrifying initialization is completed, the Bluetooth master device enters the rotation scanning mode, and continuously monitors the broadcast message of the near Bluetooth slave device; ...; 7) if the Bluetooth acquisition or measurement slave device receives the response of the Bluetooth master device, emptying the sending counter, entering into a low power consumption state, and waiting for the next data transmission. According to the non-paired fast data transmission method applied to the low power consumption Bluetooth device, the data of the Bluetooth slave machine is transmitted to the Bluetooth master machine by means of the connectionless broadcast, therefore, the identity of the Bluetooth slave machine user can be quickly verified; the Bluetooth master machine with the nearest transmission distance is matched to receive the data, therefore, the invention has the characteristics of fast transmission speed, low power consumption and high frequency and large scale use.

Description

technical field [0001] The present application relates to short-distance wireless communication technology, in particular to a non-pairing fast data transmission method suitable for low-power bluetooth devices. Background technique [0002] Bluetooth technology is a radio technology for short-distance communication. It works in the 2.4GHz ISM frequency band, supports frequency hopping and short packet technology, and supports point-to-point and multi-point communication. The launch of the Bluetooth 4.0 version in 2015, that is, the opening of the BLE (Bluetooth Low Energy) protocol, has promoted tremendous technological progress in the application of Bluetooth in the field of low-power communication. The characteristics of Bluetooth 4.0 include: global use; simultaneous transmission of voice and data; temporary peer-to-peer connection can be established; good anti-interference ability; the Bluetooth module is small in size and can be easily integrated into various devices; ...

AI Technical Summary

Problems solved by technology

Moreover, pairing is required for each measurement, and the waiting time for pairing is unbearable for medical staff and patients

In addition, most Bluetooth slave devices are powered by batteries, and data transmission in pairing mode will consume more power. Frequent charging or battery replacement is also unbearable for medical staff.

At present, there is no case of large-scale commercial use of Bluetooth measurement equipment in hospitals or similar places
