In a wireless communication system including a slave device, and a master device wirelessly connected to the slave device, the slave device includes a wireless communicator that performs wireless communication with the master device, a power supply unit that supplies power to each unit of the slave device, an interrupt detector that detects various interrupts, and a controller that controls the entire slave device, the interrupt detector supplies the power from the power supply unit to each unit of the slave device when detecting a timer interrupt occurring at predetermined intervals, and the controller performs control to perform an initialization process of the wireless communicator when the power is supplied from the power supply unit to each unit of the slave device, and perform an entire initialization process of the slave device when a capture signal is received via the wireless communicator.

Wireless communication system, and wireless communication method in wireless communication system

In a wireless communication system, a master device includes a wireless communicator that performs wireless communication with the slave device, a power supply that supplies power to each unit of the master device, an interrupt detector that detects various interrupts, and a controller that controls the entire master device, the interrupt detector supplies power from the power supply to each unit when detecting the interrupt, and the controller performs control to continuously transmit a capture signal to the slave device that waits for reception at a reception timing of a first predetermined interval, via the wireless communicator for time longer than the first predetermined interval when the detected interrupt is an interrupt that requests signal transmission to the slave device, and control to await a capture signal transmitted from the slave device through the wireless communicator when the detected interrupt is a timer interrupt occurring at a second predetermined interval.
