Wireless power transmission device transmitting charging power to wireless power receiving device and method of operating the same

Abstract

An electronic device includes a power transmitter; a first communication interface configured to support an Ultra-Wideband (UWB) communication scheme; a second communication interface configured to support a Bluetooth communication scheme; and a processor configured to: control the first communication interface to transmit a first signal and receive a second signal corresponding to the first signal via the first communication interface, identify, based on a difference between a transmission time of the first signal and a reception time of the second signal, first location information of a first external device, control the power transmitter to transmit a first driving power having a first magnitude, based on a first distance between the first external device and the electronic device being within a first range, the first distance being identified based on the first location information, establish a Bluetooth communication connection with the first external device, based on receiving, via the second communication interface, a first packet transmitted from the first external device using the first driving power, after transmitting the first driving power, and control the power transmitter to transmit a first charging power having a second magnitude, after establishing the Bluetooth communication connection.
