Esp32 power consumption bug
Posted: Fri Sep 13, 2019 8:32 am
Hi guys, I would like to know your suggestions on some issues that I have with my esp32 board.
I am using a DOIT kit to develop a low power consumption alarm system powered by a super cap. I was able to significantly drop the current consumption thanks to the ULP and deep-sleep.
Here is my problem, once the device reboots the current consumption is few mA (which is too high), however, if i plug in and out the USB the current consumption drops to normal deep-sleep consumption, around 100 uA (as it should be).
If I don't do the USB trick the current required stays in the mA range.
Do you have any thoughts on what is going on and how to solve it?
Thank you.
