Abstract: A first electronic device is provided. The first electronic device includes a communication circuit. The first electronic device may include a processor. The processor is configured to check failing to synchronize to a broadcast isochronous stream (BIS) from a third electronic device during first periodic advertisement intervals of the third electronic device indicated based on first information for synchronizing to the BIS. The processor is configured to request, through the communication circuit, second information for synchronizing to the BIS, based on the checking. The processor is configured to synchronize to the BIS during second periodic advertisement intervals of the third electronic device indicated based on the second information received through the communication circuit from the second electronic device that is paired with the first electronic device and is synchronized to the BIS.
