overview
Bluetooth broadcasting is a common wireless communication method used to transmit data over short distances. In Bluetooth broadcasting, the transmission of data is achieved by broadcasting packets, which contain specific data structures.
Broadcast structure
Bluetooth broadcast data structure refers to the organization and content format of data packets transmitted during Bluetooth broadcasting. Bluetooth broadcast data structures typically include the following important parts:
Broadcast packet struct examples:
| 0x01 | Device identification | 0x08 | Abbreviate the device name |
| 0x02 | 16Bit UUID | 0x09 | Full device name |
| 0x07 | 128Bit UUID | 0x0A | Transmit power |
| 0x19 | Device appearance | 0x0FF | Vendor-defined data |
(1) Broadcast signal type: Bluetooth broadcast packets contain broadcast signal type fields, which are used to indicate the type of packets, such as advertising packets, scan response packets, etc.
(2) Broadcast address: The broadcast data packet usually contains the Bluetooth address information of the broadcast device, which is used to identify the unique identity of the broadcast device.
(3) Broadcast data: The broadcast data packet contains the actual data content to be transmitted, which can be device information, sensor data, advertising information, etc.
(4) Checksum: In order to ensure the integrity and accuracy of the data, the broadcast packet usually contains a checksum field to verify the correctness of the 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 realized, providing users with a better wireless communication experience.
Usage scenarios
In today's hyper-connected world, Bluetooth broadcast technology is increasingly becoming ideal for connecting a wide range of smart devices. Whether in life or work scenarios, Bluetooth broadcasting has shown its unique application value. Here are some Bluetooth broadcast scenarios:
Retail environment: In a retail environment, Bluetooth broadcast technology can be used to push promotions, product descriptions, or coupons to specific stores to provide customers with a personalized shopping experience.
Indoor navigation: In large shopping malls, airports or exhibitions, Bluetooth broadcasting can be used to provide indoor navigation services to help users quickly find their destination and obtain relevant information.
Smart home: In the smart home system, Bluetooth broadcasting can be used for the interconnection between devices to realize smart lighting control, smart door locks, smart home appliances and other functions to improve the comfort and convenience of home life.
Meetings & Events: In conferences, exhibitions, concerts and other activities, Bluetooth radio can be used to provide attendees' location information, event schedules, lecture information, etc., to enhance the interactivity and participation of the event.
Health monitoring: In the field of health, Bluetooth broadcasting can be used to transmit data from health monitoring devices, such as heart rate monitoring, blood pressure monitoring, etc., to achieve remote monitoring and data collection.
Internet of Vehicles: In the automotive field, Bluetooth broadcasting can be used for communication between vehicles, realizing information exchange between vehicles, collaborative driving and other functions, and improving road safety and traffic efficiency.
With the continuous development and popularization of technology, I believe that Bluetooth broadcasting will show its great potential in more fields and bring more surprises and convenience to people's lives.
