Scan method in near-field wireless communication network and electronic device for implementing same

An electronic device comprising:

• a display;
• a short-range wireless communication circuit configured to repeatedly transmit a scan signal for finding an access point;
• a processor electrically connected to the communication circuit;
• and
• a memory electrically connected to the processor, wherein
• the memory stores instructions that, when executed, cause the processor to differentiate a transmission cycle of the scan signal according to whether a screen to be displayed when the display is turned on is a lock screen or not, if the display is turned on while no wireless connection is established with the access point.

A method for scanning an access point by an electronic device, the method comprising:

• periodically transmitting a scan signal for finding an access point at a first cycle;
• determining, if a display is turned on, whether a scan frequency needs to be adjusted or not on the basis of a triggering event that has triggered turning-on of the display;
• and
• maintaining the transmission cycle at the first cycle if the scan frequency does not need to be adjusted and changing the transmission cycle to a second cycle that is shorter than the first cycle if the scan frequency needs to be adjusted.
