Dongle and control method therefor

A dongle for relaying communication, comprising:

• a first communication interface configured to perform a wireless communication;
• a second communication interface configured to physically couple to a device comprising a processor configured to control the device, and to receive identification information of the device, wherein the device does not support a wireless communication, and wherein the dongle is configured to provide a wireless communication capability for the device;
• and
• a processor configured to:
• broadcast an advertisement signal including the received identification information,
• establish a first communication link between the first communication interface and an external device received the advertisement signal,
• receive Access Point (AP) information from the external device through the first communication link,
• establish a second communication link between the first communication interface and an AP using the received AP information,
• access a server though the second communication link,
• transmit the received identification information to the server through the second communication link,
• receive, from the server, a control program for controlling the device based on the identification information of the device received from the device,
• convert a command signal to a control signal for controlling the device using the control program in response to receiving the command signal from the server through the first communication interface,
• and output the control signal for controlling the device to the processor of the device through the second communication interface, using the received control program.
