File transmission system, electronic device, and file transmission method by same electronic device

An electronic device comprising:

• communication circuitry;
• a display;
• memory storing one or more computer programs;
• and
• one or more processors communicatively coupled to the communication circuitry, the display, and the memory,
• wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
• broadcast a search request packet for searching for an external electronic device for file transmission via the communication circuitry, and
• in case that reception of a search response packet from the external electronic device fails:
• generate quick response (QR) code data comprising information for changing the electronic device to a sharing permitted target,
• prior to connection to an external electronic device, broadcast a packet for a QR code scan request, and
• control the display to display the generated QR code data.

An electronic device comprising:

• communication circuitry;
• a camera;
• a display;
• memory storing one or more computer programs;
• and
• one or more processors communicatively coupled to the communication circuitry, the camera, the display, and the memory,
• wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
• in case that the electronic device is not connected to an external electronic device and a packet for a quick response (QR) code scan request is received from the external electronic device via the communication circuitry, scan QR code data of the external electronic device via the camera, and
• based on analysis of the scanned QR code data, control the display to provide a user interface (UI) configured to enable selection of a sharing option allowing the external electronic device to be configured as a sharing permitted target.

A file transmission method performed by an electronic device, the file transmission method comprising:

• broadcasting, by the electronic device, a search request packet for searching for an external electronic device for file transmission via communication circuitry of the electronic device;
• in case that reception of a search response packet from the external electronic device fails, generating, by the electronic device, quick response (QR) code data comprising information for changing the electronic device to a sharing permitted target;
• prior to connection to an external electronic device, broadcasting, by the electronic device, a packet for a QR code scan request;
• and
• controlling, by the electronic device, a display to display the generated QR code data.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations, the operations comprising:

• broadcasting, by the electronic device, a search request packet for searching for an external electronic device for file transmission via communication circuitry of the electronic device;
• in case that reception of a search response packet from the external electronic device fails:
• generating, by the electronic device, quick response (QR) code data comprising information for changing the electronic device to a sharing permitted target;
• prior to the electronic device being connected to another electronic device, broadcasting, by the electronic device, a packet for a QR code scan request;
• and
• controlling, by the electronic device, a display to display the generated QR code data.
