I have to configure the FlexCAN module to work as a CAN bus sniffer or in normal mode (with msg Id related to a message buffer). I have no problem to run the FlexCAN module when Message Id are known and hence, they are linked to a message buffer, but I would like to know if this module can be configured for the reception of unknown message identifiers. In this case, the CAN module should work as a gateway. It just sends what it has received. Is this possible?
Thank you in advance,
