The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0046] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

The processor (260) can be turned on based on power provided from a battery (253) through the PMIC (250), for example. The processor (260) can perform wireless communication with an external electronic device through a communication circuit (290). The processor (260) can obtain status information and / or control information of the wearable electronic device (201) and control the communication circuit (290), thereby storing the status information and / or control information of the wearable electronic device (201) in the memory (270) or transmitting the same to an external electronic device (e.g., a transmitter (301)).

[0083] In one embodiment, the first controller (280) may perform an operation for resetting the wearable electronic device (201) based on a lock-up event corresponding to an inoperable state of the processor (260) occurring or a wireless connection between the wearable electronic device (201) and an external electronic device (e.g., an electronic device such as a smart phone or a smart watch) being released. The first controller (280) may include, for example, a demodulator for decoding an NFC protocol, and the protocols supported by the first controller (280) are not limited to the examples described above. The first controller (280) may identify a command included in a received signal based on demodulating a signal received from the transmitting device (301). The first controller (280) may provide a control signal corresponding to the command to the PMIC (250) and / or the processor (260) based on the identified command.

[0084] According to one embodiment, the communication circuit (290) of the wearable electronic device (201) may transmit status information and / or control information related to wireless charging to the transmitting device (301) through the coil (210) using a wireless communication method (e.g., BLE (Bluetooth low energy) method). The communication circuit (290) may identify a command included in the received signal based on demodulating a signal received from the transmitting device (301) through the coil (210). When the processor (260) operates normally, the communication circuit (290) may provide a control signal corresponding to the command to the processor (260) based on the identified command. Referring to FIG. 4, although the communication circuit (290) is illustrated as receiving a signal from the coil (210) through the matching circuit (220), the present invention is not limited thereto, and the communication circuit (290) may also be directly connected to the coil (210).

If a forced reset of the electronic device by a second external electronic device is not performed, the electronic device may perform the reset operation and / or pairing operation based on the operation of the first controller (e.g., first controller 280). The electronic device may verify a command included in the first signal based on demodulating a first signal of a first frequency band received from the external electronic device. For example, the electronic device may verify that a value corresponding to a first bit is 1 and a value corresponding to a second bit is 0.

Although FIG. 13 illustrates the transmitting device (301) as including 16 lights, the number of lights is not limited to the above-described example. Each of the plurality of lights may be implemented as, for example, a light emitting diode (LED) configured to emit light for a predetermined time period, but is not limited thereto. The LED may emit white light for a predetermined period of time, for example, based on the control of a processor (e.g., processor (450) of FIG. 4).

In one embodiment, the transmitting device (301) may further include an LED circuit (not shown) for controlling the operation of at least some of the plurality of lights. The LED circuit may control the operation of at least some of the plurality of lights based on a control signal from the processor.

Referring to FIG. 13, the transmitting device (301) can provide an indication based on turning on at least some of the plurality of lights (1301, 1303, 1305, 1307, 1309, 1311, 1313, 1315, 1317, 1319, 1321, 1323, 1325, 1327, 1329, 1331) for a predetermined time period based on the first event being confirmed.

The number of times at least some of the lights are repeatedly turned on may be changed according to a setting. Based on the transmitter device (301) confirming the first event, the indication provided through at least some of the plurality of lights (1301, 1303, 1305, 1307, 1309, 1311, 1313, 1315, 1317, 1319, 1321, 1323, 1325, 1327, 1329, 1331) is not limited to the examples described above.
