Abstract

The embodiment of the invention discloses an Internet of Things message issuing method and device, electronic equipment and a storage medium. The Internet of Things message issuing method can comprisethe following steps of sending a request message for requesting synchronization; after the request message is sent, a receiving window being opened; receiving a response message returned for the request message through the receiving window; determining whether the time of the terminal device and the time of the gateway device are synchronous according to the receiving condition information of theresponse message; if the time of the terminal device and the time of the gateway device are synchronized, adding the terminal device and the gateway device into a multicast group; and receiving a downlink multicast message sent by the management equipment based on the multicast group. Therefore, batch control of a plurality of devices can be realized through one or a few downlink data.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a method and device for sending messages of the Internet of Things, electronic equipment, and a storage medium. Background technique [0002] In the low-power wide-area network LPWAN industry of the Internet of Things, especially in the LoRaWAN network used for long-distance communication LoRa radio frequency, there are many applications that need to use batch downlink. For example: in light control applications, it is necessary to turn off all Lights, etc.; as another example, in the process of remote software upgrades for devices, batch downlinks are required. In the existing solution, downlink data is transmitted to each device separately to complete the downlink of all devices in the project, which takes a long time and puts a certain amount of traffic pressure on the gateway device and the network protocol server. Contents of the invention [0003] In view of...
