Abstract

The application relates to the technical field of communications, and discloses a data transmission method and device. The method comprises the following steps: a first terminal sends a first audio signal for pairing to a second terminal, wherein the audio signal comprises an identification code of the first terminal; the first terminal analyzes the received audio signal from the second terminal, and encodes the to-be-transmitted data and the identification code of the first terminal after determining that the second terminal allows the pairing according to an analysis result, thereby generating a third audio signal; and the first terminal sends the third audio signal to the second terminal. The application is used for providing a new mode for transmitting the information between the terminals, the problems that the information transmission mode under the close range scene in the prior art is narrow in application range and has boundedness are solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data transmission method and device. Background technique [0002] The development of smart terminals has brought more convenience to people's daily work and life. People can use mobile devices to meet office and entertainment needs such as surfing the Internet, sending and receiving emails, and browsing multimedia data, and can also transmit data information through the network. At present, data transmission is very extensive in real life. Users mainly transmit data through wired methods such as telephone lines, USB (Universal Serial Bus, Universal Serial Bus) interfaces or special cables, or use mobile Internet, wifi (Wireless Fidelity, WIreless-FIdelity), infrared, Bluetooth and other wireless technologies for data transmission. [0003] In short-distance (within a few centimeters to a few meters) scenarios, people often interact with each other. For e...
