Abstract: An electronic device is provided. The electronic device includes a communication module supporting communication based on Bluetooth Low Energy (BLE), and a processor operatively coupled to the communication module. The processor is configured to transmit control information to request the communication module to operate in a first mode. Upon receiving an advertising Packet Data Unit (PDU) of predefined types from an external electronic device, the first mode corresponds to a mode of controlling the communication module so that a scan request is transmitted to the external electronic device in response to reception of the advertising PDU of the predefined types. The communication module is configured to receive the advertising PDU from the external electronic device, while operating in the first mode, on the basis of the control information, identify that a type of the received advertising PDU corresponds to a first type distinct from the predefined types, on the basis of a header included in the received advertising PDU, bypass transmission of the scan request on the basis of the identifying, and transmit to the processor an advertising notification for representing that the advertising PDU of the first type has been received.

Abstract: An electronic device and method are disclosed herein. The electronic device includes memory storing a certificate list including first certificate data of the electronic device, and second certificate data of an external electronic device, a short-range wireless communication circuit, and a processor. The processor implements the method, including: detecting a trigger event for requesting establishment a communication connection with a device local to the electronic device, controlling the short-range wireless communication circuit to broadcast an advertisement packet generated based on the first certificate data, in response to detecting the trigger event, receiving a response packet from the external electronic device and acquire a third certificate data from the received response packet, authenticating the external electronic device based on the second certificate data and the third certificate data, and establishing a secure communication channel with the external electronic device if the external electronic device is authenticated.
