Abstract
An electronic device is provided. The electronic device includes a plurality of antennas to communicate with an external electronic device and at least one processor operatively connected to the plurality of antennas. The processor is configured to detect a tracking start event using an external magnetic material positioned at a location adjacent to the electronic device, to track a location of the external electronic device using the plurality of antennas and, while the tracking is performed, to obtain a height value of the external electronic device when an angle between the electronic device and the external electronic device is a specified angle. The processor is further configured to change a specified condition based on the obtained height value, to detect a tracking end event based on the specified condition, and to change an operating mode associated with the electronic device in response to detecting the tracking end event.
