Abstract: An electronic device is provided, which includes a first communication circuit supporting a neighbor awareness networking (NAN) protocol; a second communication circuit configured to support a second protocol different from the NAN protocol; a memory; and a processor operatively connected to the first communication circuit, the second communication circuit, and the memory. The processor is configured to activate the NAN protocol supported by the first communication circuit, receive data from at least one external electronic device during a discovery window (DW) interval synchronized in a cluster via the first communication circuit, identify whether identification information of the at least one external electronic device having transmitted the data is stored in the memory, if the identification information of the at least one external electronic device is stored in the memory, store, in the memory, information that is obtained by matching at least a part of the received data with the identification information, and if a request for performing a service is received, display information of the at least one external electronic device configured to perform the service, based on the information stored in the memory.

Abstract: According to various embodiments, a method of controlling data communication of an electronic device, the method comprising performing the directional wireless communication together with an external electronic device capable of performing the directional wireless communication and the omni-directional wireless communication, by using the first wireless communication circuit, determining the distance between an electronic device and the external electronic device, at least partially on the basis of a signal of the external electronic device received by using the second wireless communication circuit, when the stop or degradation of the directional wireless communication is detected, and determining whether to reattempt the directional wireless communication using the first wireless communication circuit, at least partially on the basis of the determined distance or to start the omni-directional wireless communication using the second wireless communication circuit. Other embodiments are possible.
