AFAIK you cannot power save whilst being able to receive on CAN without losing data, unless the ESP32 is the only device on the bus doing the ACK, then there should be retransmits.
Exactly - key point is to be the only other device on the bus (but if MIL-CAN even that does not work). You must wake up and ACK before the transmitter goes bus off and/or ANO accepts the message whilst you sleep.
& I also believe that IDF CAN should be fixed.
