Method and device for transmitting data, and method and device for receiving data

An electronic device comprising:

• a communication interface configured to establish a communication link between the electronic device and an external device by using a first application being executed in the electronic device;
• a display configured to display, on a touch screen of the electronic device, a first window that corresponds to the first application, and a second window that corresponds to a second application being executed in the electronic device;
• and
• a processor configured to:
• set an operation mode of the electronic device as a sharing mode, based on a first user input on the first window, and
• control the communication interface to transmit data from the electronic device to the external device, via the communication link, wherein the data is selected based on a second user input on the second window via a user interface,
• wherein the first window displays connection time information about the communication link between the electronic device and the external device,
• wherein the first window moves in a state of being overlapped with the second window based on a third user input, and
• wherein the processor is further configured to set the operation mode of the electronic device as a synchronization mode based on a fourth user input of dragging the first window to a side portion of the touch screen.

A non-transitory computer-readable medium storing instructions executable by a processor of an electronic device, to cause the processor to:

• establish a communication link between the electronic device and an external device by using a first application being executed in the electronic device;
• display, on a touch screen of the electronic device, a first window corresponding to the first application and a second window corresponding to a second application being executed in the electronic device;
• set an operation mode of the electronic device as a sharing mode based on a first user input on the first window;
• and
• transmit data from the electronic device to the external device via the communication link, wherein the data is selected based on a second user input on the second window, and
• wherein the first window displays connection time information about the communication link between the electronic device and the external device,
• wherein the first window moves in a state of being overlapped with the second window based on a third user input, and
• wherein the setting the operation mode comprises setting the operation mode of the electronic device as a synchronization mode based on a fourth user input of dragging the first window to a side portion of the touch screen.
