Abstract
A device determining method, an electronic device, and a computer-readable storage medium are provided. The method includes: determining a first angle of arrival (AOA) of a signal from a target device in a first direction and a second AOA of the signal in a second direction; acquiring a status of the signal between the terminal and the target device in response to determining that the first AOA and the second AOA are within a first preset angle range; and determining the target device as a device to be selected according to the status of the signal between the terminal and the target device.
