External equipment, data transmission method, device and system

Abstract

The embodiments of the invention disclose external equipment, a data transmission method, device and system. The external equipment comprises a main control chip, a Bluetooth chip, an UART (Universal Asynchronous Receiver Transmitter) chip, a data conversion chip and a USB interface chip, wherein the main control chip is connected with the Bluetooth chip and the UART chip respectively, and the data conversion chip is connected with the UART chip and the USB interface chip respectively. The external equipment transmits data to a first terminal via the Bluetooth chip, and transmits data to a second terminal via the UART chip, the data conversion chip and the USB interface chip, thereby realizing data transmission between the first terminal and the second terminal, e.g., realizing data transmission between a smart phone and a computer under various systems; the external equipment has good compatibility, so that a user working with a computer can know notification messages received by a mobile phone without frequently viewing the mobile phone; corresponding notification feedback information can be input to the computer, so that the working efficiency of the user is not influenced; and the external equipment, which adopts Bluetooth communication and does not depend on a wifi router, is applicable to the scenes without wifi signals and low in power consumption.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an external device, a data transmission method, device and system. Background technique [0002] With the accelerating pace of modern life and the continuous improvement of people's living standards, the use of computers and smart phones has become more and more popular in people's daily life. It has become a common way to use computers to work and communicate with others through smart phones. life pattern. [0003] Under normal circumstances, the smart phone cannot transmit the received notification message to the computer, so that the user who uses the computer to work can know the content of the notification message in time. The user needs to interrupt the work in hand, unlock the smart phone and read the message to understand the content of the notification message content, which brings inconvenience to the user's work and affects the user's work efficiency. ...

Problems solved by technology

[0003] Under normal circumstances, the smart phone cannot transmit the received notification message to the computer, so that the user who uses the computer to work can know the content of the notification message in time. The user needs to interrupt the work in hand, unlock the smart phone and read the message to understand the content of the notification message content, which brings inconvenience to the user's work and affects the user's work efficiency

[0004] In order to solve the above problems, in the prior art, the function of transmitting the notification information of the mobile phone to the computer can be realized through bluetooth or wifi (wireless-fidelity, wireless fidelity) between the computer under the Mac OS system and the mobile phone under the iOS system; However, it is difficult to achieve this function between mobile phones under the iOS system and mobile phones under the Android system, and computers under the Windows system; Android phones can realize this function through a wifi LAN and a computer under the Windows system, but it is very dependent on the wifi router. It is difficult to implement this function when working outside, and there are information security issues; in addition, the solution of using wifi for LAN data transmission does not support mobile phones under the iOS system
