Hello,
I would like to develop a low power consumption application.
My application goes into deep-sleep mode and is woken up by activating an RTC timer. I have measured that the wake up time is around 160 ms and it is too much for my application. I think this time is due to the boot of free rtos, but I'm not sure.Is it possible to reduce this time considerably?
In addition, what are the parameters to set to lower power consumption to a minimum?

Thank you very much.

It depends what you want to do when you wake up. Look at wake stubs and ulp coprocessor programs.

When I wake up, I want to send a packet with ESPNOW protocol with Wifi. I can't use ULP for this stuff. I have to wake up from deep sleep and and send a message...
