- Sat Mar 18, 2017 6:30 am #63886 I have trying to get the current down to 10uA during deep sleep. As per specs on page 18
http://www.exp-tech.de/pdf/products/ESP ... ule-EN.pdf

The best I can do is 0.36 mA. I tried 3 different ES12F modules like the ones below.
https://tronixlabs.com.au/wireless/esp8 ... australia/

I been testing these modules stand alone, so not on a breadboard with any regulator or USB / Serial components.

This is the sample code I have been using to test.

// Time to sleep (in seconds):
const int sleepTimeS = 15;

void setup()
{

// Serial
Serial.begin(115200);
delay(10);
Serial.println("");
Serial.println("ESP8266 Woke Up");

// Sleep
Serial.println("ESP8266 Going To Slepp");
//ESP.deepSleep(sleepTimeS * 1000000,WAKE_RF_DEFAULT );
ESP.deepSleep(sleepTimeS * 1000000,WAKE_RF_DISABLED );

}

void loop()
{

}

Any help would be appreciated.

- Mon Mar 20, 2017 3:06 am #63989 It should work. How have you wired it up - what pull ups/down etc. 0.36mA is suspiciously close to the current with a 10k resistor across the power supply. Show us a photo?

Thanks you both for the reply. Unfortunately still 0.36 mA in sleep. Also tried another meter just in case.
I must admit, I haven't tried removing the resistors and just tying the appropriate pins vcc / GND
