control the communication interface to operate in the AP mode, based on the first AP information.

10 . The electronic apparatus of claim 1 , wherein the one or more processors are further configured to execute the at least one instruction:

control the communication interface to operate in the AP mode, based on the first AP information and a preset event;

wherein the preset event comprises at least one of an event in which a communication connection based on the first AP information is identified as being released, or an event in which a user command for operating in an AP mode is identified based on the first AP information.

11 . The electronic apparatus of claim 1 , wherein the one or more processors are further configured to execute the at least one instruction to:

control the communication interface to operate in the AP mode based on a preset event;

wherein the preset event comprises at least one of an event in which a communication connection based on the first AP information is released in the at least one external device, or an event in which a user command to operate in the AP mode is identified based on the first AP information.

12 . A method of controlling an electronic apparatus, the method comprising:

operating a communication interface of the electronic apparatus in an access point (AP) mode based on first AP information; and

based on at least one external device being communicatively connected during operation of the communication interface in the AP mode, transmitting second AP information different from the first AP information to the at least one external device.

13 . The method of claim 12 , further comprising:

terminating the AP mode based on a preset event,

wherein the preset event comprises at least one of an event in which a preset time has elapsed after operating in the AP mode, an event in which a preset time has elapsed after transmitting the second AP information to the at least one external device, an event in which the second AP information is transmitted to each device in a target device list, or an event in which an end request of the AP mode is identified.

14 . The method of claim 13 , further comprising:

based on the first AP information being released, obtaining the second AP information from a user terminal through a Wi-Fi communication by executing SoftAP function; and

obtaining the target device list through the Wi-Fi communication.

15 . The method of claim 14 , further comprising:

transmitting a request signal to the user terminal, the request signal requesting whether to transmit the second AP information to the at least one external device; and

receiving from the user terminal the target device list based on the request signal.
