Claim 11:
12. A method of wireless communication with a seat belt comprising:
causing each secondary controller to wake up through wireless communication in a sleep state of the each secondary controller;
transmitting, by the each secondary controller, a secondary data signal comprising a state-of-a-buckle signal resulting from detection by a seat belt sensor provided on a per-seat basis, through the wireless communication;
receiving and storing, by a primary controller, the secondary data signal wirelessly transmitted from the each secondary controller and transmitting, by the primary controller, the stored secondary data signal to a vehicle system controller;
causing the secondary controller to switch to the sleep state after the secondary data signal is transmitted; and
causing the secondary controller to switch to the sleep state when the primary controller does not properly receive the secondary data signal, when the secondary controller retransmits the secondary data signal, and, when the number of times the secondary data signal is retransmitted is greater than a predetermined number of times.
