Power consumption to high!

Postby xxopiumxx » Fri Jul 20, 2018 10:12 pm

Hi!,

I know that this has been discused several times, but I cannot find a recent post about it.
I am having a current consumption of ~100-170mAh, and in this proyect I do not use WIFI nor BT; but cannot find any way to disable this modules / radio .
I am workign under the lastest release of the esp-idf.

Any help will be much appreciated.

thanks!

I've notice that firmware compiled using macOs has more consumption then if it was compiled under Linux or Windows, possible drivers issue. I'm not officialy esp32 staff but you should have a try to use USB 2.0 physical interface where you ESP32 is pulgin. Check your code. Tell us more how do you mesure the current.

Numbers are somewhat dependent on the AP (how precise its beacon interval is), but you should get 5-8mA for DTIM=1 and around 2mA for DTIM=5.
