What do you mean 'running the CAN bus'?

Do you mean 'will the hardware generate the ACK whilst in sleep mode'?
I don't know but easy enough to test with two ESPs back to back.

Running CAN means i need to wake-up esp when ever data from CAN bus without any data loss

And also am worrying about WiFi Ap's DTIM period and beacon interval, how much it will affect the power consumption of esp32

If you use an external can controller maybe you can use light sleep, otherwise probably not much.

THANK YOU

In Wifi whats the benefits of beacon interval and DTIM

Can you please suggest me the benefits of beacon interval and DTIM and in which power save mode its useful means shall we use these in light sleep and deep sleep also, because in light sleep and deep seep we are putting wifi to off then switching esp to power save mode so that?
