摘要

Constant efforts have been made to reduce a size of electronic equipment incorporating a radio device. However, it has been impossible to simply and reliably establish a radio connection between pieces of electronic equipment. There are provided a radio system including a plurality of first radio devices that have statuses thereof changed at the time of receiving a predetermined signal, and a second radio device that has an input device 11 of sequentially transmitting a status change command as the predetermined command in order to establish a radio connection, the status change command causing all or some of the plurality of first radio devices to have statuses thereof changed. The status changes are externally output by the first radio devices receiving the status change command. A first radio device to act as a target of the radio connection is determined on the basis of information related to the externally output status changes.
