System and method for communication between a commander device and a responder device

A method, comprising:

• receiving, by a responder device of a set of responder devices, messages from a commander device conveying identifiers identifying the responder device as the one of the responder devices to which the messages are addressed, wherein the messages are encoded in a CAN FD format using a serial peripheral interface (SPI) protocol, and each message of the messages comprises a CRC field and a CRC delimiter following the CRC field;
• and
• verifying, by the responder device, a correctness of the CRC field and a presence of the CRC delimiter.

A non-transitory computer readable medium with instructions stored thereon, wherein the instructions, when executed by a processor of a responder device in a set of responder devices, enable the processor to perform the steps of:

• receiving messages from a commander device conveying identifiers identifying the responder device as the one of the responder devices to which the messages are addressed, wherein the messages are encoded in a CAN FD format using a serial peripheral interface (SPI) protocol, and each message of the messages comprises a CRC field and a CRC delimiter following the CRC field;
• and
• verifying a correctness of the CRC field and a presence of the CRC delimiter.
