1. Overview

Bluetooth broadcast is a common wireless communication method used to transmit data over short distances. In Bluetooth broadcast, data is transmitted through broadcast packets, and these packets contain specific data structures.

  1. Broadcasting structure

The Bluetooth broadcast data structure refers to the organizational form and content format of the data packets transmitted during the Bluetooth broadcast process. The Bluetooth broadcast data structure usually includes the following important parts:

Broadcast packet structure example:



Equipment Identity


Abbreviated device name


16Bit UUID


Full device name


128Bit UUID


Transmit power


Equipment appearance


Manufacturer customized data

① Broadcast signal type: The Bluetooth broadcast packet contains a broadcast signal type field, which is used to indicate the type of data packet, such as advertising packets, scan response packets, etc.

②Broadcast address: The broadcast packet usually contains the Bluetooth address information of the broadcast device, which is used to identify the unique identity of the broadcast device.

③Broadcast data: The broadcast data packet contains the actual data content to be transmitted, which can be device information, sensor data, advertising information, etc.

④ Check code: In order to ensure the integrity and accuracy of the data, broadcast data packets usually contain a check code field to verify the correctness of the data packet.

The Bluetooth broadcast data structure is designed to achieve efficient data transmission and identification while ensuring data security and reliability. By rationally designing the structure of broadcast data packets, fast connection and data exchange between devices can be achieved, providing users with a better wireless communication experience.

  1. Usage scenarios
