Abstract
Controller area network (CAN) communications apparatus and methods are presented for CAN flexible data rate (CAN FD) communications in a mixed CAN network with CAN FD nodes and one or more non-FD CAN nodes in which a CAN FD node wishing to transmit CAN FD frames sends a first predefined message requesting the non-FD CAN nodes to disable their transmitters before transmitting the CAN FD frames, and thereafter sends a second predefined message or a predefined signal to return the non-FD CAN nodes to normal operation.
