Abstract

An embodiment of the invention provides a control method and a control device. The control method comprises the following steps of: when first electronic equipment and third electronic equipment are provided with a first data transmission channel, and the third electronic equipment and second electronic equipment are determined to have the first data transmission channel through the third electronic equipment, judging whether the second electronic equipment is provided with a second data transmission channel so as to obtain a judging result; when the second electronic equipment is determined to have no second data transmission channel according to the first judging result, obtaining equipment information of the second electronic equipment through the third electronic equipment; and establishing the second data transmission channel with the second electronic equipment according to the equipment information of the second electronic equipment. According to the embodiment of the invention, the equipment information of the second electronic equipment can be conveniently and effectively obtained, so that the second data transmission channel with the second electronic equipment can be effectively established.

Description

technical field [0001] The present application relates to the field of electronic technology, and more specifically relates to a control method and device. Background technique [0002] With the development of electronic technology, how to realize fast, effective and low-consumption information interaction between electronic devices has become an important research direction in the future. [0003] To achieve information exchange between electronic devices, it is necessary to establish a data transmission channel and connect. There are many existing methods for establishing a data transmission channel. For example, devices located in the same local area network can be connected. [0004] To establish a data transmission channel between electronic devices, it is necessary to obtain each other's device information, such as the LAN port number of the device, before initiating a connection request. In the existing technology, the acquisition of device information usually adopt...
