Classification: CPC H  G | IPC H

Claim 0:
1. An electronic device comprising:
a power transmitter;
a first communication circuit configured to support an Ultra-Wideband (UWB) communication scheme;
a second communication circuit configured to support a Bluetooth communication scheme;
a processor; and
a memory storing instructions that, when executed by the processor, cause the electronic device to:
control the first communication circuit to transmit a first signal and receive a second signal corresponding to the first signal, the second signal transmitted by a first external device,
identify, based on a difference between a transmission time of the first signal and a reception time of the second signal, a first distance between the first external device and the electronic device,
control the power transmitter to transmit a first driving power having a first magnitude, based on the first distance between the first external device and the electronic device being within a first range,
establish a Bluetooth communication connection with the first external device, based on receiving, via the second communication circuit, a first packet transmitted by the first external device based on 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.
