Whenever the address information is received, the master device can be stored in combination with a communication address of a logical address at which to store the received logical address, which is inconsistent with the determined communication address received recurrence logical address received.
The present invention relates to a wireless communication system, the logical address is detected stably repeated. (Slave Nmax of the maximum number of connections, the address notification period T) based on information from the master slave (1) and the set number #n to the own device, the notification time ΔT is calculated address information in the slave apparatus, the delay ΔT after the time period T in each its own address information (a communication address logical address +) notified to the master device. Whenever the address information is received, the master device can be stored in combination with a communication address of a logical address at which to store the received logical address with the case where the same logical address has been stored in combination with the logical address checks of stored communication address, is inconsistent with the determined communication address received recurrence logical address received. Further, in order to perform the next repetition judgment, rewriting the communication address stored in the logical address into a combination of the received communication address.
