The communication module 190 may include one or more communication processors that can operate independently from the processor 120 (e.g., an application processor (AP)) and support direct (e.g., wired) communication or wireless communication. According to an 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 (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth (BT), Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a cellular network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip), or these various types of communication modules can be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

A signal or power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

[0057] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, general purpose input output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0058] According to an embodiment, a command or data may be sent or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199.

For example, the communication circuit 290 may transmit direction information (e.g., motion sensor data) of the digital pen 201 obtained by the trigger circuit 298, voice information input through a microphone, or level information of the battery 289. For example, the short-range communication method may include at least one of Bluetooth Low Energy (BLE) or a wireless LAN.

[0069] According to an embodiment, the antenna 297 may be used to transmit a signal or power to the outside (e.g., the electronic device 101), or to receive a signal or power from the outside. According to an embodiment, the digital pen 201 may include a plurality of antennas 297, and at least one antenna 297 suitable for the communication method may be selected from among the plurality of antennas 297. The communication circuit 290 may exchange a signal or power with an external electronic device through the at least one antenna 297 thus selected.

[0070] According to an embodiment, the trigger circuit 298 may include at least one button or sensor circuit. According to an embodiment, the processor 220 may identify an input mode (e.g., touch or press) or type (e.g., EMR button or BLE button) of a button of the digital pen 201.

[0100] Reference Figure 8, the electronic device 101 may measure the state of the wireless communication link 520 in a state (e.g., in the first state 801) in which the wireless communication link 520 is established with the digital pen 201. For example, the electronic device 101 may measure the state of the wireless communication link 520 by measuring the strength (or interference level) of the signal received from the digital pen 201. According to an embodiment, during the first state 801, the electronic device 101 may display a first GUI 511 indicating the battery state of the digital pen 201 and a second GUI 512 indicating the state of the wireless communication link 520 through the display 160.

[0101] According to an embodiment, the electronic device 101 may detect that the wireless communication link 520 is released based on the measured state of the wireless communication link 520 or user settings. In the state where the wireless communication link 520 is released (e.g., in the second state 802), the electronic device 101 may provide an effect that the second GUI 512 disappears. In other words, the electronic device 101 may not display the second GUI 512, and may only display the first GUI 511.

[0102] According to an embodiment, the electronic device 101 may attempt to reestablish the wireless communication link 520. For example, the electronic device 101 may display a screen indicating that the wireless communication link 520 is released through the display 160, and may perform the reconstruction in response to a user input selecting the reconstruction of the wireless communication link 520. For another example, the electronic device 101 may automatically perform the reconstruction of the wireless communication link 520 without user input. In a state where the electronic device 101 and the digital pen 201 reestablish the wireless communication link 520 (for example, in the third state 803), the electronic device 101 may provide an effect that the first GUI 511 flashes.

[0104] Reference Fig. 9 In operation 905 of flowchart 900, electronic device 101 may measure the state of wireless communication link 520. According to an embodiment, electronic device 101 may measure the state of wireless communication link 520. Figure 6 Operation 905 is performed between operation 605 and operation 625 .

[0105] In operation 910, the electronic device 101 may identify whether the wireless communication link 520 is released based on the measurement result. For example, when the strength of the signal received from the digital pen 201 is less than a specified threshold, the electronic device 101 may determine that the wireless communication link 520 is released. When the wireless communication link 520 is not released, the electronic device 101 may repeatedly perform operations 905 and 910.

[0106] When the wireless communication link 520 is released, the electronic device 101 may provide an effect that the second GUI 512 disappears in operation 920. The electronic device 101 may display only the first GUI 511 on a partial area of ​​the display 160 (eg, the indicator bar 505).

[0107] In operation 925, the electronic device 101 may attempt to reestablish the wireless communication link 520. In operation 930, the electronic device 101 may provide an effect of the first GUI 511 flashing while reestablishing the wireless communication link 520. According to an embodiment, operations 925 and 930 may be performed substantially simultaneously.

[0108] When the wireless communication link 520 is established, the electronic device 101 may display the second GUI 512 indicating the connection status of the wireless communication link 520 in operation 935.

For example, the electronic device 101 may establish the wireless communication link 520 based on the Bluetooth standard or the BLE standard.

[0115] According to an embodiment, the electronic device 101 may display a GUI 510 including at least one of the first GUI 511 or the second GUI 512 based on whether the digital pen 201 is detached. For example, when the electronic device 101 detects that the digital pen 201 is detached (e.g., the first state 1001), the electronic device 101 may display the GUI 510 through the display 160. For another example, when the electronic device 101 detects that the digital pen 201 is inserted (e.g., the second state 1002), the electronic device 101 may not display the GUI 510 on the display 160.

According to an embodiment, the appearance of each of the multiple digital pens (e.g., 201-1 and 201-2) (e.g., at least one of the pen housing 300, the first end 300a, or the second end 300b) can have a different color. For example, in the embodiment to be described below, the first digital pen 201-1 can have a blue appearance, and the second digital pen 201-2 can have a red appearance. However, the various colors are not limited thereto.
