Electronic device including light emitting device and operating method thereof

An external device comprising:

• a wireless communication circuit configured to communicate with an electronic device and an internet of things (IoT) device;
• and
• a control circuit electrically connected with the wireless communication circuit and configured to register the IoT device, wherein the control circuit is configured to:
• select a flashing pattern of the electronic device to emit light toward the IoT device,
• control the wireless communication circuit to transmit a first signal comprising information indicating the selected flashing pattern to the electronic device,
• after transmitting the first signal, receive, from the electronic device via the wireless communication circuit, a response signal comprising flashing pattern information that is determined based on illuminance sensed by the IoT device, and
• based on the selected flashing pattern and the received flashing pattern information, register the IoT device.

An operating method of an electronic device which comprises a light emitting device, the operating method comprising:

• establishing wireless communication with an external device;
• when the wireless communication is established, receiving a first signal from the external device;
• and
• in response to the received first signal, emitting light using the light emitting device according to a flashing pattern, wherein the flashing pattern is selected from a plurality of flashing patterns, each flashing pattern corresponding to a different location, indicating at least a part of a location of the electronic device, and
• in response to emitting light, receiving, from an internet of things (IoT) device, a second signal comprising flashing pattern information that is determined based on an illuminance sensed by the IoT device.

A method for registering, by an external device, an internet of things (IoT) device, the method comprising:

• selecting a flashing pattern of an electronic device to emit light toward the IoT device;
• transmitting a first signal comprising information indicating the selected flashing pattern to the electronic device;
• after transmitting the first signal, receiving, from the electronic device, a response signal comprising flashing pattern information that is determined based on an illuminance sensed by the IoT device;
• and
• registering the IoT device based on the selected flashing pattern and the received flashing pattern information.
