Wireless module transparent transmission principle and process analysis [Copy link]

Transparent transmission, as the name implies, means that the transmission process is completely transparent to the outside world, and there is no need to pay attention to the transmission process and transmission protocol. The ultimate goal is to pass the transmitted content to the receiving end intact, and the sent and received content are completely consistent. In wireless modules, transparent transmission is usually achieved through specific technologies and mechanisms.

The principle of transparent transmission of wireless modules is mainly based on transparent transmission of serial port data. In this transmission mode, the wireless module is configured as transparent transmission mode. No matter what data the sender sends, the wireless module will forward it to the receiver intact. When sending data, the data is encapsulated into a specific frame format and sent to the receiver through the wireless channel. After receiving the data, the receiver will automatically remove the frame format and pass the original data to the upper-layer application.

The transparent transmission process is as follows:

1. Configure the wireless module to transparent transmission mode. This usually involves some initialization and parameter settings for the module.
2. The transmitter sends the data to be transmitted to the wireless module through the serial port or other interfaces.
3. After receiving the data, the wireless module encapsulates it into a specific frame format and sends it to the receiving end through the wireless channel.
4. After receiving the data frame, the wireless module at the receiving end automatically removes the frame format and passes the original data to the upper-layer application through the serial port or other interface.

The advantages of transparent transmission are mainly reflected in the following aspects:

1. Simplify the development process: In transparent transmission mode, the wireless module does not process the transmitted data. Developers do not need to pay attention to the underlying communication details, but only need to focus on the transmission of upper-layer application data, which greatly simplifies the development process.
2. Ensure data integrity: Transparent transmission can ensure the integrity and consistency of data, avoiding the risk of data modification or loss during transmission.
3. Improve communication efficiency: Since there is no need for additional data processing, transparent transmission can reduce delays and overhead in the communication process and improve communication efficiency.
4. High flexibility: Transparent transmission mode is suitable for various types of data transmission, whether it is text, image or audio and video data, it can be transmitted through transparent transmission.

In general, the transparent transmission function of the wireless module is an efficient and reliable data transmission method. The transparent transmission module is widely used in the fields of Internet of Things, smart home, industrial automation, etc. Through transparent transmission, fast and accurate data exchange between devices can be achieved, promoting the rapid development of intelligent applications.
