6. The electronic device of claim 5 , wherein the first mode configures the communication circuitry to:

receive a scan response transmitted from the external electronic device in response to the scan request, and

transmit an advertising notification to the at least one processor in response to the received scan response.

7. The electronic device of claim 1 , wherein the communication circuitry is further configured to:

identify whether predefined data among remaining data other than the header is included in the received advertising PDU; and

transmit an advertising notification to the at least one processor in response to the identifying of the predefined data.

8. The electronic device of claim 7 , wherein the predefined data comprises a Universally Unique IDentifier (UUID).

9. The electronic device of claim 8 , wherein the UUID corresponds to information for identifying the external electronic device.

10. The electronic device of claim 4 ,

wherein the advertising notification comprises a Media Access Address (MAC) address of the external electronic device and Received Signal Strength Indication (RSSI) information, and

wherein the external electronic device comprises an electronic pen mountable to a housing of the electronic device.

11. An electronic device comprising:

a user interface;

a wireless communication circuit configured to support Bluetooth Low Energy (BLE) wireless communication, and upon receiving an advertising Packet Data Unit (PDU) of a predefined type from an external electronic device, to request the external electronic device for additional information; and

at least one processor operatively coupled to the user interface and the wireless communication circuit,

wherein the wireless communication circuit is configured to:

receive the advertising PDU, the PDU comprising a header and a payload, from the external electronic device,

identify a type of the advertising PDU included in the header of the advertising PDU,

identify a data type included in the payload of the advertising PDU, and

transmit an advertising notification to the at least one processor on the basis of data included in the advertising PDU and withhold transmission of the additional information request to the external electronic device, if the identified type of the advertising PDU is the predefined type and at least one of the data types comprises a selected identifier.

12. The electronic device of claim 11 , wherein the predefined type comprises at least one of an ADV_IND type, an ADV_SCAN_IND type, an ADV_NONCONN_IND type, or an ADV_DIRECT_IND type.

13. The electronic device of claim 11 , wherein the advertising notification comprises at least one of a type of the data included in the advertising PDU, a Bluetooth address of the external electronic device, or a Received Signal Strength Indication (RSSI).

14. The electronic device of claim 11 ,

wherein the electronic device comprises a memory operatively coupled to the at least one processor, and

wherein the memory stores instructions, when executed, for allowing the at least one processor to request the wireless communication circuit to establish a connection with the external electronic device in response to reception of the advertising notification.

15. The electronic device of claim 11 , wherein the external electronic device comprises a stylus pen.

16. An electronic device comprising:

a user interface;

a wireless communication circuit configured to support Bluetooth Low Energy (BLE) wireless communication and to receive an advertising Packet Data Unit (PDU) comprising a header including a field indicating a type of an advertising PDU from an external electronic device; and

at least one processor operatively coupled to the user interface and the wireless communication circuit,

wherein the wireless communication circuit is configured to:

receive, from the external electronic device, the advertising PDU not including information on the electronic device,

identify that a type of the advertising PDU included in the header of the advertising PDU is a first type, and

transmit to the at least one processor an advertising notification on the basis of data included in the advertising PDU and withhold transmission of an additional information request to the external electronic device in response to identification that the type of the advertising PDU is the first type.

17. The electronic device of claim 16 ,

wherein the wireless communication circuit is further configured to transmit a connection initiation to the external electronic device, and

wherein the first type does not correspond to a connectable undirected event, connectable directed event, non-connectable undirected event, or scannable undirected event of a BLE standard.

18. The electronic device of claim 16 , wherein the information on the electronic device comprises a Bluetooth address of the electronic device.
