These terms are used to distinguish the same type of information from each other. For example, the first information may also be referred to as the second information without departing from the scope of the invention. Similarly, the second information may also be referred to as the first information. Depending on the context, in addition, the word "if" may be interpreted as "when", or "when", or "in response to determination."

A data transmission method is proposed in the embodiment of the present invention. Referring to FIG. 1, the method can be applied to a system including a drone, a screen remote controller, and a mobile terminal (ie, a smart terminal such as a mobile phone).

In order to improve the ease of use of the drone, the drone can be opened out of the box, and the remote control can be provided on the remote control. The remote control with the display is called a remote control with a screen. Among them, the screen remote controller has the function of a mobile terminal, can download and store image data, and complete various interaction functions with the drone.

A variety of social software (such as WeChat, QQ, etc.) can be installed on the remote control with a screen. The remote control with a screen has a WiFi (Wireless Fidelity) interface, which can access the Internet through a wireless router. In addition, the screen remote control can also access the Internet through a carrier network (such as 2G/3G/4G, etc.).

In one example, in order to share the image data collected by the drone, the drone can transmit the image data to the screen remote controller, and the screen remote controller can save these images locally after receiving the image data. Image data and share these image data through the carrier network.

However, in order to share image data through the carrier network, a SIM (Subscriber Identification Module) card needs to be added to the screen remote controller, which increases the cost of using the screen remote controller.

In the first method, the mobile terminal generates a first WiFi hotspot (for the convenience of distinguishing, the WiFi hotspot generated by the mobile terminal may be referred to as a first WiFi hotspot), and provides the first WiFi hotspot to the screen remote controller. The screen remote controller searches for the first WiFi hotspot provided by the mobile terminal, and establishes a second communication link with the mobile terminal through the first WiFi hotspot. At this point, the establishment process of the second communication link is completed.

Specifically, the WiFi hotspot function of the mobile terminal can be turned on, so that the mobile terminal has the WiFi router function, and a first WiFi hotspot with a password can be generated, and the first WiFi hotspot is provided to the screen remote controller. The screen remote controller can view the first WiFi hotspot by searching for the first WiFi hotspot provided by the mobile terminal, and after inputting the password, can connect to the first WiFi hotspot. In this way, the screen remote controller and the mobile terminal can establish a second communication link through the first WiFi hotspot.

In the second mode, the second remote WiFi hotspot is generated by the remote control device (for the convenience of distinguishing, the WiFi hotspot generated by the screen remote controller may be referred to as a second WiFi hotspot), and the second WiFi hotspot is provided to the mobile terminal. The mobile terminal searches for a second WiFi hotspot provided by the screen remote controller, and establishes a second communication link with the screen remote controller through the second WiFi hotspot, and thus completes the establishment process of the second communication link.

Specifically, the WiFi hotspot function with the screen remote controller can be turned on, so that the screen remote controller has the WiFi router function, can generate a second WiFi hotspot with a password, and provide the second WiFi hotspot to the mobile terminal. The mobile terminal can view the second WiFi hotspot by searching the second WiFi hotspot provided by the screen remote controller, and after inputting the password, can connect to the second WiFi hotspot.
