Abstract
Each of relay terminals transmits a wireless packet received from a wireless sensor and a reception strength of Bluetooth wireless communication to a control device using a first HCI packet, and returns a response to the wireless packet to a source wireless sensor, which is a source of the wireless packet, only when a second HCI packet is received from the control device. The control device compares the reception strengths, among the reception strengths received through the first HCI packets from the relay terminals, that pertain to the same packet transmitted from the same wireless sensor and received by the plurality of relay terminals, transmits the second HCI packet only to one target relay terminal having the highest reception strength, and relays the sensor data stored in the target relay device to a host device.
