When a wired interface circuit (22) receives a CEC message destined for a node device connected through a wireless transceiver circuit (24), a CEC controller (21A) of a wireless node device (20) outputs an ACK for the received CEC message from the wired interface circuit (22), transmits a wireless data packet containing contents of the CEC message from the wireless transceiver circuit (24), and waits for the wireless interface transceiver circuit (24) to receive a wireless ACK packet for the transmitted wireless data packet. |
