Problems solved by technology
At present, when a terminal is connected to a wireless access point (Wireless Fidelity Access Point, WiFi AP) for data transmission, the channel is determined according to the WiFi AP, without considering the channel condition of the terminal, which will cause the data sent by the WiFi AP to the terminal to fail. Receiving or parsing errors, etc.; therefore, how to ensure efficient data transmission between the terminal and the WiFi AP is a technical problem that needs to be solved

The present invention provides a data transmission method, comprising: a first device sends first information including first channel information on at least one channel; the first channel information is used to represent a channel used by the first device to receive data; The first device receives second information including second channel information sent by the second device based on the first channel; the second channel information is used to characterize the channel used by the second device to receive data; the first device based on The second channel sends first confirmation information, and the first confirmation information is used to confirm that the channel through which the first device sends data is the second channel, and the channel through which the first device receives data is the first channel; wherein, the first The channel is the channel corresponding to the first channel information, and the second channel is the channel corresponding to the second channel information; the present invention also provides the first device, the second device and the storage medium; through the present invention, it is possible to ensure that the first device and the second device efficiently transfer data between them.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data transmission method, a first device, a second device and a storage medium. Background technique [0002] Wireless Fidelity (Wireless Fidelity, WiFi) has incomparable advantages over wired networks such as easy installation, flexible use, economical savings, and easy expansion, so it is being used more and more widely. At present, when a terminal is connected to a wireless access point (Wireless Fidelity Access Point, WiFi AP) for data transmission, the channel is determined according to the WiFi AP, without considering the channel condition of the terminal, which will cause the data sent by the WiFi AP to the terminal to fail. Receiving or parsing errors, etc.; therefore, how to ensure efficient data transmission between the terminal and the WiFi AP is a technical problem that needs to be solved. Contents of the invention [0003] The present inve...
