Abstract:
When a wired interface circuit receives a CEC message destined for a node device connected through a wireless transceiver circuit, a CEC controller of a wireless node device outputs an ACK for the received CEC message from the wired interface circuit, and transmits a wireless data packet containing contents of the CEC message from the wireless transceiver circuit. The CEC controller also waits for the wireless interface transceiver circuit to receive a wireless ACK packet for the transmitted wireless data packet.
