A method and an apparatus for communicating with an external device using a beam in an electronic device supporting beamforming are provided. The electronic device includes a wireless communication circuitry, an antenna array including a plurality of antenna elements, and at least one processor. The processor may be configured to form and transmit a beam corresponding to a direction of the electronic device based on a start of a service, monitor reception of a response signal corresponding to the beam from an external device, and performs pairing with the external device based on at least a part of the response signal if the response signal is received.
