Electronic device for controlling communication connection with input device and method of controlling same

An electronic device, comprising:

• a housing including an inner space;
• a hole formed through the housing to the inner space;
• a stylus pen insertable into the inner space through the hole, wherein the stylus pen includes a first wireless communication circuit and a wireless charging receiver circuit;
• a wireless charging transmitter circuit positioned inside the housing and configured to provide charging to the wireless charging receiver circuit when the stylus pen is inserted into the inner space;
• a second wireless communication circuit positioned inside the housing;
• at least one processor operatively connected to the wireless charging transmitter circuit and the second wireless communication circuit;
• and
• at least one memory operatively connected to the at least one processor, wherein the at least one memory stores instructions that, when executed, cause the at least one processor to:
• detect whether the stylus pen is inserted into the inner space,
• start to provide charging for a first duration to the wireless charging receiver circuit, using the wireless charging transmitter circuit after detecting that the stylus pen is inserted into the inner space,
• scan for a wireless signal from the first wireless communication circuit, using the second wireless communication circuit after the starting to provide charging,
• receive the wireless signal from the first wireless communication circuit, using the second wireless communication circuit,
• stop providing charging for the first duration to the wireless charging receiver circuit, after receiving the wireless signal, and
• transmit a connection request using the second wireless communication circuit to the first wireless communication circuit.
