I am trying to speed up the boot time after deep-sleep, and activating logs at the debug level, I get the output below.
I don't understand what it means, except that it looks like the first 279ms are spent to manage the RTC clock calibration.
Am I correct?
Do you see any way to fasten this?
I am using the ESP-IDF to develop the app and configure the hardware.
Many thanks!
