AI Technical Summary

Technical Problem

In various gateway usage scenarios, when a server transmits data to a Bluetooth tag, the gateway may be unable to establish a connection in a timely manner due to communication quality or distance issues, affecting the reliability and stability of data transmission.

Method used

After receiving the connectable broadcast packet from the Bluetooth tag, the gateway obtains command data from the server and sends a connection request message to the Bluetooth tag, ensuring that at least one of the multiple gateways successfully establishes a connection with the Bluetooth tag and transmits command data in a timely manner.

Benefits of technology

This improves the reliability and stability of data transmission, avoiding command data transmission failures caused by the gateway's inability to establish a connection with the Bluetooth tag in a timely manner.

Abstract

This application provides a data transmission method, a gateway, and a Bluetooth tag. The data transmission method includes: a gateway receiving a connectable broadcast packet from a first Bluetooth tag, wherein the gateway has not received command data from the first Bluetooth tag from a server before receiving the connectable broadcast packet; the command data is used for data transmission, and the connectable broadcast packet indicates that the Bluetooth tag is in a connectable state; the gateway sending a connection request message to the first Bluetooth tag based on the connectable broadcast packet; and the gateway sending command data to the first Bluetooth tag upon receiving a connection request confirmation message from the first Bluetooth tag, wherein the command data is obtained by the gateway from the server after receiving the connectable broadcast packet from the first Bluetooth tag. This data transmission method enables multiple gateways to establish connections with the first Bluetooth tag, promptly transmits command data to the first Bluetooth tag, and improves the stability of data transmission.
