Screen projection method, receiving end device, and sending end device

A screen projection method, which is applied to a sending end device, comprising:

• searching for a receiving end device by using a preset wireless scanning technology;
• establishing a wireless connection with the receiving end device when the receiving end device is found;
• and
• receiving and displaying a screen projection code sent by the receiving end device to prompt a screen projection operation;
• wherein establishing a wireless connection with the receiving end device when the receiving end device is found, comprises:
• sending a connection request packet that carries identification information indicating whether the sending end device has opened a screen projection software to the receiving end device;
• establishing the wireless connection with the receiving end device if the identification information indicates that the sending end device has opened the screen projection software.

A receiving end device comprising a wireless module and a transmission module, wherein:

• the wireless module is configured for searching for a sending end device by using a preset wireless scanning technology, and establishing a wireless connection with the sending end device when the sending end device is found,
• the transmission module is configured for acquiring a screen projection code, and sending the screen projection code to the connected sending end device, so that the connected sending end device displays the screen projection code to prompt a screen projection operation;
• wherein the wireless module is further configured for:
• sending a request packet to the sending end device when the sending end device is found;
• receiving a response packet fed back by the sending end device, wherein the response packet carries identification information indicating whether the sending end device has opened a screen projection software;
• establishing the wireless connection with the sending end device when it is determined that the sending end device has opened the screen projection software based on the identification information.
