esp32 - 50mA minimum.

[MadDogMayCry0]

Hello

I did radio off by:

#include <WiFi.h>
void setup() {
WiFi.mode(WIFI_OFF);
btStop();
}

but esp32 still consume 50mA of currency.
In datasheet it's described as a 10mA in modem sleep mode.

What wrong?

1- By default the Arduino Core runs always at the maximum speed, so you'll always be in the worst case
2- This table consider only the ESP32, if you are using any dev board, there are more components than the ESP32...

1 - How to settings this on medium? :)
2 - I use ESP-WROOM-32 and put battery direct to 3v3 pin.

It's not very simple, but it's possible

@copercini
You mean i can change it only in esp-idf?

Thx you for a Link, but it's only gives to me 37mA - still no 10mA

@Stasikiii yes, it can only be change using IDF, but the result will produce the @lbernstone file, so using https://github.com/lbernstone/arduino-esp32-80MHz procedure you can skip the IDF proccess

@copercini thx you!

Maybe you need to cool it to absolute zero 😄 . The testing is done in isolation, without any flash, lights, or gpio traces. You are working in the real world, with a real OS running. esp32-solo-1 modules should be arriving in stores soon, which will be as efficient as you can go with esp32. If you need less power, you get less power...

Another tips: if you remove the USB to serial converter, LEDs, switch to a better LDO (if you are using one), remove everything except the ESP, I think you can get the 10mA
