CAN BUS Interrupt Pin

[cosmin91]

Hi, I've tried a lot of code versions, but seems like I'm not able to wake up the esp32 when I receive a new CAN message. It's probably a hardware limitation, but just want to double check if there is something that will trigger the wakeup pin on esp32 when there is can bus activity.
Thanks,
Cosmin

Do you mean esp32 in sleep mode? CAN interrupt??

@lewisxhe yes, exactly.

ESP does not have a separate wake-up function for CAN
