Abstract

In a system that performs communication between master and slave, the device better suited as the master device is not always the master device, since the device that initially constructs the network becomes the master device. A device that enters the network later transmits a restart request on detecting the master device, and if a restart permission is received, the device transfers to a restart state and transmits a master inquiry before the device that was the master device up until that point. Thus, a device that newly enters a network is able to operate as the master device even if a master device already exists in the network.
