Moreover, at present, the function of the earphone interface of most terminals is relatively single, that is, it is connected with audio equipment such as earphones, so as to realize the functions of listening to music and answering calls.
[0003] However, when a user needs to transmit a business card or picture to another user's terminal, it can only be transmitted through bluetooth or wifi
These wireless transmission methods are relatively complicated and limited by the environment. When there are relatively large interference signal sources in the environment, the above wireless transmission methods cannot be used

The invention discloses a data transmission method, a terminal and a data line. The method is applied to a first terminal, and the first terminal has a first interface, and the first interface has a first working mode for transmitting audio signals and a second working mode for transmitting binary data signals, and the method includes: when When the first interface is connected to the second interface of the second terminal, set the first terminal to the first working mode; when the second terminal connected to the first interface is an audio device, set the second A terminal is set to the second working mode. By adopting the method, terminal or data line of the present invention, by using the existing earphone interface and other interfaces on the terminal to realize data transmission, the function of the terminal interface in the prior art can be expanded, and the data transmission can be made simpler, and the Interference from other signal sources.
Description
technical field [0001] The invention relates to the field of data control, in particular to a data transmission method and a terminal. Background technique [0002] Current electronic devices, especially terminals such as mobile phones, usually have an audio interface, such as a 3.5mm earphone interface. Moreover, most of the earphone interfaces of terminals currently have a single function, that is, they are connected to audio equipment such as earphones, so as to realize the functions of listening to music and answering calls. [0003] However, when a user needs to transmit a business card or picture to another user's terminal, the transmission can only be carried out through bluetooth or wifi. These wireless transmission methods are relatively complicated and limited by the environment. When there is a relatively large interference signal source in the environment, the above wireless transmission methods cannot be used. Contents of the invention [0004] The purpose o...
