Screen casting method, electronic device, storage medium, and program product

A method of screen casting, comprising:

• initiating, by a screen casting target device in response to an operation of initiating Bluetooth advertising, Bluetooth low energy (BLE) advertising, wherein the BLE Bluetooth advertising data comprises a first data packet and a second data packet, the first data packet comprises first verification information and encrypted information, the second data packet comprises second verification information and a key, the key is used to decrypt the encrypted information, and the encrypted information comprises device information and wireless connection information;
• receiving a wireless connection request sent by a screen casting source device, and establishing a wireless connection to the screen casting source device based on the wireless connection request;
• and
• performing video screen casting via the wireless connection.

An electronic device, comprising:

• a memory configured to store computer program instructions;
• and
• a processor configured to execute the program instructions, wherein when the computer program instructions are executed by the processor to cause the electronic device to:
• in response to an operation of initiating screen casting, initiate a Bluetooth low energy (BLE) advertising search;
• receive found BLE Bluetooth advertising data;
• obtain a first data packet and a second data packet from the BLE Bluetooth advertising data, wherein the first data packet comprises first verification information and encrypted information, and the second data packet comprises second verification information and a key;
• decrypt the encrypted information by using the key, and obtaining device information and wireless connection information from the decrypted encrypted information;
• determine, based on the first verification information and the second verification information, that the first data packet and the second data packet are associated screen casting information;
• display a screen casting device selection interface, wherein an alternative device option that corresponds to one or more pieces of screen casting information determined in the BLE Bluetooth advertising data is displayed on the screen casting device selection interface, and the alternative device option comprises the device information in the corresponding one or more pieces of screen casting information;
• in response to an operation of selecting a screen casting target device option of the alternative device option, send a wireless connection request to a screen casting target device based on the wireless connection information in the screen casting information that corresponds to the screen casting target device option, and establishing a wireless connection to the screen casting target device;
• and
• initiate video screen casting to the screen casting target device via the wireless connection.
