Re: power save in esp32 with running can bus
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.

& I also believe that IDF CAN should be fixed.

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

Re: power save in esp32 with running can bus
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?

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. You can wake the ESP32 on CAN bus activity due to change in level on the Rx pin.

Hi
Thank you, for your reply,
Okay we will use CAN as GPIO wake-up.
Can you please help me in another task there am using both Bluetooth and WiFi, and trying to put esp32 to light by configuring auto light sleep enable, but its not working esp32 is still consuming 100mA
