Electronic device including electronic pen and method of controlling communication connection between electronic device and electronic pen

A method of controlling a communication connection by an electronic device, the method comprising:

• detecting whether an electronic pen is inserted into a recess inside a housing of the electronic device;
• charging the electronic pen through a wireless charging circuit based on the detection;
• receiving inherent information of the electronic pen through a wireless communication circuit during or after the charging;
• and
• maintaining or re-establishing the communication connection with the electronic pen based on a portion of the received inherent information.

An electronic device comprising:

• a housing;
• a touch-screen display exposed through a portion of the housing;
• a first wireless communication circuit disposed inside the housing;
• a recess disposed inside the housing;
• a first wireless charging circuit disposed inside the housing to be adjacent to the recess;
• a processor disposed inside the housing and operatively coupled to the display, the first wireless communication circuit, and the first wireless charging circuit;
• and
• a memory operatively coupled to the processor,
• wherein the memory stores instructions causing the processor to, when executed:
• detect whether an electronic pen is inserted into the recess,
• charge the electronic pen through the first wireless charging circuit based at least in part on the detection,
• perform a scan through the first wireless communication circuit in order to identify information on the electronic pen,
• turn on or off the first wireless charging circuit in a predetermined pattern in response to discovery of a plurality of electronic pens through the scan,
• identify the electronic pen inserted into the recess among the plurality of electronic pens based on charging-related information included in advertising signals received from the plurality of found electronic pens, and
• establish a communication connection with the identified electronic pen.
