Embodiment Construction

[0028] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0029] Long Range Radio (LoRa) is a low-power LAN wireless standard created by Semtech. LoRa has the characteristics of low power consumption, low cost, long transmission distance, and easy networking. It is widely used in IoT fields such as smart communities, smart homes, smart meters, smart agriculture, and smart logistics.

[0030] In the existing LoRa networking, a LoRa networking system will support multiple channels, some are 8 channels, some are 32 channels, and LoRa devices located in different channels cannot communicate with each other. Generally speaking, a LoRa network The channel of all LoRa devices is the same.

[0031] The communication protocol of the existing LoRa device is fixed, the encryption method is simple, and all LoRa devices are in the same channel, which leads to network ...

Abstract

The invention provides a communication method and device based on a LoRa channel and a LoRa host, and the method comprises the steps: obtaining the current configuration information of a LoRa slave, and enabling the current configuration information to comprise a first channel where the LoRa slave is located; switching to a first channel where the LoRa slave is located and sending configuration information to the LoRa slave, the configuration information including to-be-configured address information and to-be-configured channel information, and an address corresponding to the to-be-configured address information being different from an address of the LoRa host; and switching to a channel corresponding to the to-be-configured channel information and communicating with the LoRa slave based on the configuration information, thereby effectively improving the communication security of the LoRa networking system.

Description

technical field [0001] The present application relates to the communication field, in particular, to a LoRa channel-based communication method, device and LoRa host. Background technique [0002] Long Range Radio (LoRa) is a low-power local area network wireless standard with low power consumption, low cost and long transmission distance. In the existing LoRa network, all LoRa devices of a LoRa network are generally located on the same channel. Since the communication protocol of the existing LoRa device is fixed, the encryption method is simple and all LoRa devices are in the same channel, which leads to network attackers who can obtain the data of the LoRa device after determining the address and channel of a LoRa device. Then, maliciously control each LoRa device in the channel by analyzing the communication protocol of the LoRa device, thus causing serious network security problems. Contents of the invention [0003] The purpose of the embodiment of the present appli...
