Method for pairing devices using near field communication and electronic apparatus using same

1. An electronic apparatus comprising:

a first wireless communication module for supporting a first wireless communication;

a second wireless communication module for supporting a second wireless communication;

a memory; and

a processor operatively connected to the first wireless communication module, the second wireless communication module, and the memory,

wherein the processor is configured to:

detect a tag of an external electronic apparatus through the first wireless communication module,

transmit a first command for driving a designated application of the external electronic apparatus to the external electronic apparatus through the first wireless communication module,

receive Bluetooth address information of the external electronic apparatus corresponding to the driving of the designated application through the first wireless communication module, and

perform pairing with the external electronic apparatus through the second wireless communication module, based on the received Bluetooth address information, and

wherein the first command is further configured to cause the external electronic apparatus to change a mode from a reader mode or a peer-to-peer mode state to a card emulation mode state.

2. The electronic apparatus of claim 1 , wherein the processor is configured to execute a predetermined application for pairing with the external electronic apparatus when the tag of the external electronic apparatus is detected.

3. The electronic apparatus of claim 2 , wherein the processor is configured to activate a POS function installed in the memory when the predetermined application is executed.

4. The electronic apparatus of claim 1 , wherein the processor is configured to emit a radio frequency signal to the external electronic apparatus through the first wireless communication module to be connected to the external electronic apparatus through the first wireless communication, when the tag of the external electronic apparatus is detected.

5. The electronic apparatus of claim 1 , wherein the first wireless communication supports a near field communication (NFC) protocol, and the second wireless communication supports a Bluetooth protocol.

6. The electronic apparatus of claim 1 , wherein the processor is configured to receive a first response signal indicating that the designated application is normally executed in the external electronic apparatus through the first wireless communication module.

7. The electronic apparatus of claim 6 , wherein the processor is configured to transmit a second command for identifying a Bluetooth address of the external electronic apparatus to the external electronic apparatus through the first wireless communication module, and

receive a second response signal including the Bluetooth address through the first wireless communication module.

8. The electronic apparatus of claim 1 , wherein the first command comprises a protocol used in an NFC card emulation.

9. A method for an electronic apparatus to pair with an external electronic apparatus, the method comprising:

detecting a tag of an external electronic apparatus through a first wireless communication module,

transmitting a first command for driving a designated application of the external electronic apparatus to the external electronic apparatus through the first wireless communication module,

receiving a first response signal indicating that the designated application is executed from the external electronic apparatus through the first wireless communication module;

transmitting a second command for requesting Bluetooth address information of the external electronic apparatus through the first wireless communication module;

receiving the Bluetooth address information through the first wireless communication module; and

performing pairing with the external electronic apparatus through a second wireless communication module, based on the Bluetooth address information,

wherein the first command is further configured to cause the external electronic apparatus to change a mode from a reader mode or a peer-to-peer mode state to a card emulation mode state.

10. The method of claim 9 , further comprising:

executing a predetermined application, by the electronic apparatus, and

activating a point of sale (POS) function installed in a memory, by the electronic apparatus, when the predetermined application is executed.

11. The method of claim 9 , further comprising:

emitting a radio frequency signal to the external electronic apparatus to be connected to the external electronic apparatus through the first wireless communication module, by the electronic apparatus, when the tag of the external electronic apparatus is detected.

12. The method of claim 9 , wherein the first wireless communication supports a near field communication (NFC) protocol, and the second wireless communication supports a Bluetooth protocol.

13. The method of claim 9 , wherein the first command comprises an association identifier of the designated application.

14. The method of claim 13 , further comprising:

extracting the association identifier from the first command, and

executing the application registered as the association identifier, by the electronic apparatus.

15. The method of claim 9 , further comprising:

receiving a second response signal including the Bluetooth address of the external electronic apparatus corresponding to the second command, by the electronic apparatus.
