Abstract: A central transmits, to a peripheral connected with the central, re-connection information indicating a timing of a re-connection after a disconnection. Subsequently, the central executes a connection discontinuing process based on the re-connection information. In addition, the central controls power supply for wireless communication at a timing determined based on the re-connection information. Thereafter, the central executes a re-connection process with the peripheral based on the re-connection information shared therewith prior to the disconnection.
