In an electronic device and an operation method for same according to various embodiments, the electronic device comprises: a communication circuit for transmitting and receiving data through a plurality of links, including a first link and/or a second link, generated between the electronic device and an external electronic device; and a processor operatively connected to the communication circuit. The processor may be set to control the communication circuit to: determine whether to scan the first link and the second link simultaneously or sequentially on the basis of the characteristics of the first link and the second link; upon determining to scan the first link and the second link sequentially, perform at least one operation for stopping the transmission and/or reception of data through the first link and transmitting and/or receiving data through the second link before performing the scan of the first link; and transmit and/or receive data through the second link while performing the scan of the first link. Various other embodiments are possible.
