i just finished an esp32 design with incredibly aggressive power savings as the primary goal
it saves persistent variables to non-volatile storage and deep-sleeps at 15-20uA according to my power profiler 2, waking up on a timer
when it wakes up, connects, checks battery, and updates display, it can peak 350mA, but mostly stays around 100-150mA while it works
- steve_adams_86 4y agoAwesome, I've been curious about deep sleeping. How long does it take to come back online?
- jareklupinski 4y agoCorrelating to current measurements, my first Serial log shows up almost as soon as I can see the current spiking from waking up (within a half-second) I haven't timed it super precisely (my off-state is 30 min and my on-state is 4-5 seconds), but definitely going to check this for thoroughly in my next project, which will wake from deep sleep on button press; curious if there's some delay as everything powers on.
