Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
Referring to fig. 2, an embodiment of the present invention provides a method for establishing a wifi link, including:
In this embodiment, the communication link refers to a path space through which electromagnetic waves propagate between the AP and the STA. For example, the communication link includes a wifi link, i.e. a link connected through a wifi hotspot, as well as a 5.8G remote control link, i.e. a communication link between the drone and the remote controller, and so on.
The wifi hotspot refers to a technology that the AP converts a received General Packet Radio Service (GPRS) signal, or a 3G signal, or a 4G signal into a wifi signal to send out. After the STA is accessed to the wifi hotspot of the AP, the WIFI signal sent by the AP can be received, so that communication is realized. For example, after the unmanned aerial vehicle takes a picture or a video, the picture or the video is sent to the remote controller through the wifi link.
In this embodiment, the AP may establish a communication link different from the wifi link with the STA when wifi hotspot information needs to be sent to the STA, for example, after the AP is powered on and started up, or is powered back on again, or when a wifi channel changes.
In this embodiment, the communication link different from the wifi link is a 5.8G remote control link, it can be understood that the 5.8G remote control link is only one implementation of the communication link different from the wifi link, and in other embodiments, according to a specific application or a difference between STAs, there may be other communication links different from the wifi link, which is not listed here.
The following describes a process of establishing a communication link different from a wifi link, taking a 5.8G remote control link as an example:
after the STA enters a 5.8G remote control link establishment mode, the STA broadcasts the machine identification of the STA on all channels of the 5.8G remote control link; after the AP enters the establishment mode of the 5.8G remote control link, the AP receives the machine identification identifier broadcast by the STA from one of the channels in the 5.8G remote control link, records the received machine identification identifier, replies a confirmation message to the STA, and completes a handshake action, so that the establishment of the 5.8G remote control link is completed.
In this embodiment, after recording the machine id of the STA, the AP does not establish a 5.8G remote control link with other STAs. That is, one AP can establish a 5.8G remote control link with only one STA.
Wherein, the user can press the 5.8G remote link establishment button of the AP for a long time to enable the AP to enter a 5.8G remote link establishment mode; the user may cause the STA to enter the 5.8G remote control link establishment mode by simultaneously pressing the power key of the STA and the 5.8G remote control link establishment button.
In this embodiment, the wifi hotspot information includes: a wifi name, a wifi Media Access Control (MAC) address, and a wifi channel.
Optionally, the wifi hotspot information further includes: wifi password and Service Set Identifier (SSID), among other information.
In one embodiment, the hotspot information includes a wifi channel, and after receiving the hotspot information sent by the AP, the STA directly scans the corresponding wifi channel (e.g., channel 1) to discover the wifi hotspot connected to the AP.
In one embodiment, when the wifi channel changes due to the restarting of the AP, the AP sends a new wifi channel to the STA through the communication link different from the wifi link, and the STA directly configures the new wifi channel after receiving the new wifi channel without scanning the wifi channel again.
Fig. 3 is a schematic diagram illustrating an AP sending wifi hotspot information to an STA in an embodiment of the present invention. As shown in fig. 3, the AP sends wifi hotspot information to the STA through a communication link different from the wifi link, so that the STA can connect to the wifi hotspot only by scanning a wifi channel in the wifi hotspot information without scanning all channels once, thereby shortening the time for establishing the wifi link, i.e., increasing the speed for establishing the wifi link.
It can be appreciated that when the STA needs to establish a wifi link with another AP, the STA will re-establish a new communication link with the new AP, which is different from the wifi link, so that the STA connects to the wifi hotspot of the new AP.
In the above method, the AP and the STA may be any terminal device, for example, the AP is an unmanned aerial vehicle, and the STA is a remote controller. In this case, the unmanned aerial vehicle transmits the pictures, videos and the like shot by the unmanned aerial vehicle to the remote controller through the wifi link, so that the real-time transmission of the pictures, videos and the like can be effectively improved by establishing the wifi link through the method of the embodiment of the invention.
Referring to fig. 4, an embodiment of the present invention provides a method for establishing a wifi link, including:
In this embodiment, the communication link different from the wifi link is a 5.8G remote control link, it can be understood that the 5.8G remote control link is only one implementation of the communication link different from the wifi link, and in other embodiments, according to a specific application or a difference between STAs, there may be other communication links different from the wifi link, which is not listed here.

In this embodiment, the wifi hotspot information includes: a wifi name, a wifi Media Access Control (MAC) address, and a wifi channel.
Optionally, the wifi hotspot information further includes: wifi password and Service Set Identifier (SSID), among other information.
