Abstract: The embodiments disclosed in the present disclosure relate to a method for reconnecting Bluetooth communication and a device supporting the same. An electronic device according to various embodiments of the present invention comprises: a Bluetooth communication circuit including a control circuit; a processor electrically connected to the Bluetooth communication circuit; and a memory electrically connected to the processor, wherein the memory stores an instruction that causes the processor to provide a reconnection request to the control circuit when Bluetooth communication with an external device is disconnected, and the control circuit can attempt to reconnect the Bluetooth communication with the external device by periodically transmitting a connection request for the Bluetooth communication to the external device for a predetermined time period without repeatedly calling application programming interfaces (API's) received from the processor, in response to the reception of the reconnection request.

Abstract: An electronic device and a method are disclosed. The electronic device includes a housing, a display, a first communication circuit, a detection circuit, a memory, and a processor. The detection circuit is configured to detect a stylus pen when the stylus pen including a second communication circuit is located within a predetermined distance range from the display. The processor is operably connected to the display, the first communication circuit, the detection circuit, and the memory. The processor is configured to receive a signal containing unique identification information from the stylus pen. The processor is also configured to execute a first application program while receiving an input generated based on a touch by the stylus pen on the display or generated based on a movement of the stylus pen detected within the predetermined distance range. The processor is further configured to associate the unique identification information with the first application program.
