2. The control method of claim 1 , wherein the identifying the standby time comprises:
based on the distance information indicating that a distance between the electronic apparatus and the external device is a first distance, identifying a first period time as the standby time; and
based on the distance information indicating that the distance between the electronic apparatus and the external device is a second distance, which is greater than the first distance, identifying a second period time longer than the first time as the standby time.
3. The control method of claim 1 , wherein the identifying the standby time comprises:
based on the distance information indicating that a distance between the electronic apparatus and the external device is a first distance, identifying a first time as the standby time;
increasing the first time based on an increased distance between the electronic apparatus and the external device, such that the electronic apparatus and the external device become farther apart than the first distance; and
decreasing the first time based on a decreased distance between the electronic apparatus and the external device, such that the electronic apparatus and the external device become becoming closer than the first distance.
4. The control method of claim 3 , further comprising:
based on the increased distance between the electronic apparatus and the external device becoming farther apart by the reference radius or more, controlling to not perform the connection with the external device.
5. The control method of claim 1 , wherein the performing the connection with the external device comprises:
based on the external device being located within the reference radius, controlling a projector to project information corresponding to the standby time.
6. The control method of claim 5 , further comprising:
based on the increased distance between the external device and the electronic apparatus, controlling the projector to project information notifying that the standby time for performing the connection with the external device is increased; and
based on a decreased distance between the external device and the electronic apparatus, controlling the projector to project information notifying that the standby time for performing the connection with the external device is decreased.
7. The control method of claim 1 , wherein the identifying the external device comprises:
identifying a plurality of external devices located within the reference radius; and
identifying one of the plurality of external devices, which is closest to the electronic apparatus as the external device to perform the connection with the electronic apparatus.
8. The control method of claim 1 , wherein the identifying the external device comprises:
identifying a plurality of external devices located within the reference radius; and
identifying one of the plurality of external devices with a history of having performed connection with the electronic apparatus as the external device to perform the connection with the electronic apparatus.
9. The control method of claim 1 , wherein the identifying the external device comprises identifying the external device located within the reference radius with the electronic apparatus through a Bluetooth Low Energy (BLE) method.
10. The control method of claim 1 , wherein the obtaining the distance information comprises obtaining, by using at least one from among a Bluetooth Low Energy (BLE) method and a Time of Flight (ToF) sensor, the distance information between the identified external device and the electronic apparatus.
11. An electronic apparatus comprising:
a memory configured to store at least one instruction;
a communication interface; and
a processor configured to execute the at least one instruction to:
identify whether an external device is located within a reference radius of the electronic apparatus,
based on the external device being located within the reference radius, obtain distance information between the identified external device and the electronic apparatus,
identify a standby time based on the distance information, and
based on the standby time elapsing, control the communication interface to perform connection with the external device,
wherein the standby time indicates a period of time from a first time at which the external device is identified to a second time at which the connection with the external device begins.
12. The electronic apparatus of claim 11 , wherein the processor is further configured to execute the at least one instruction to:
based on the distance information indicating that a distance between the electronic apparatus and the external device is a first distance, identify a first period time as the standby time, and
based on the distance information indicating that the distance between the electronic apparatus and the external device is a second distance, which is greater than the first distance, identify a second period time longer than the first time as the standby time.
13. The electronic apparatus of claim 11 , wherein the processor is further configured to execute the at least one instruction to:
based on the distance information indicating that a distance between the electronic apparatus and the external device is a first distance, identify a first time as the standby time,
increase the first time based on an increased distance between the electronic apparatus and the external device, such that the electronic apparatus and the external device become farther apart than the first distance, and
decrease the first time based on a decreased distance between the electronic apparatus and the external device, such that the electronic apparatus and the external device become becoming closer than the first distance.
14. The electronic apparatus of claim 13 , wherein the processor is further configured to execute the at least one instruction to, based on the increased distance between the electronic apparatus and the external device becoming farther apart by the reference radius or more, control the communication interface to not perform the connection with the external device.
15. The electronic apparatus of claim 11 , further comprising:
a projector configured to project a projection image,
wherein the processor is further configured to execute the at least one instruction to, based on the external device being located within the reference radius, control the projector to project information corresponding to the standby time.
16. The control method of claim 1 , wherein the standby time is a variable time that changes after the external device is identified and before the beginning of the connection with the external device.
