Pairing method based on BLE applet

Abstract

The invention provides a BLE-based applet pairing method, which relates to the technical field of Bluetooth, and comprises the following steps: pairing sending, network connection establishment, verification code generation, verification code input, verification code verification and pairing completion. According to the invention, the BLE control end is close to the BLE module equipment end for broadcasting, the discovery frame is sent to the to-be-paired BLE module equipment end in a mode of dynamically adjusting the power consumption, the BLE module equipment end receives the broadcast packet, establishes network connection, and sends the pairing reply frame to the BLE control end by adjusting the sending power consumption to be low power consumption according to the BLE signal strength. The BLE control end synchronously generates a verification code for pairing, the BLE control end receives the reply frame, pops up an interface capable of inputting the verification code, sends a verification pairing frame to the BLE module device end for verification and returns a verification result, the BLE control end stores the device locally according to the verification result and completes pairing, in conclusion, verification code visualization is achieved, and BLE power consumption is dynamically adjusted.

Description

technical field [0001] The invention relates to the technical field of bluetooth, in particular to a pairing method based on a BLE applet. Background technique [0002] The current Bluetooth pairing technology uses a fixed operation to open the pairing window period or the Bluetooth pairing of some devices is always open. When the window period is open, any user can connect to the device. In this case, the user device is easily blocked. Other people control, there is no security at all; device control methods currently include infrared, radio frequency, bluetooth, network (wifi), etc. Infrared and radio frequency do not have the pairing function, and the network requires a certain network environment, while bluetooth does not need wifi The wireless network can also realize local network distribution and control; in the home or some fixed scenes, the BLE Bluetooth control display is more safe and practical, and the BLE module has the ability to dynamically adjust the power co...

Problems solved by technology

[0002] The current Bluetooth pairing technology is to open the pairing window period through a fixed operation or the Bluetooth pairing of some devices is always open. When the window period is open, any user can connect to the device. In this case, the user device is easily blocked. Other people control, there is no security at all; device control methods currently include infrared, radio frequency, bluetooth, network (wifi), etc. Infrared and radio frequency do not have the pairing function, and the network requires a certain network environment, while bluetooth does not need wifi The wireless network can also realize local network distribution and control; in the home or some fixed scenes, the BLE Bluetooth control display is more safe and practical, and the BLE module has the ability to dynamically adjust the power consumption, which cannot be achieved by wifi. Dynamic adjustment The power consumption can control the device according to the signal strength, which is more secure in terms of safety;

[0003] Among them, in the control of some home appliances such as air conditioners, a Bluetooth remote control is generally required for control. However, in the existing connection and pairing method, it is difficult to achieve device pairing interaction without a remote control, and the Bluetooth connection is easy to be controlled by others. , there is no safety at all, therefore, the present invention proposes a method based on BLE applet pairing to solve the problems existing in the prior art
