Which version of ArduinoESP and SDK are you using ?

From tools/sdk/include/user_interface.h

Code: Select allenum rst_reason {
        REASON_DEFAULT_RST              = 0,    /* normal startup by power on */
        REASON_WDT_RST                  = 1,    /* hardware watch dog reset */
        REASON_EXCEPTION_RST    = 2,    /* exception reset, GPIO status won’t change */
        REASON_SOFT_WDT_RST     = 3,    /* software watch dog reset, GPIO status won’t change */
        REASON_SOFT_RESTART     = 4,    /* software restart ,system_restart , GPIO status won’t change */
        REASON_DEEP_SLEEP_AWAKE = 5,    /* wake up from deep-sleep */
        REASON_EXT_SYS_RST      = 6             /* external system reset */
};


From core/esp82766/ESP.cpp

Code: Select allString EspClass::getResetReason(void) {
    char buff[32];
    if (resetInfo.reason == REASON_DEFAULT_RST) { // normal startup by power on
      strcpy_P(buff, PSTR("Power on"));
    } else if (resetInfo.reason == REASON_WDT_RST) { // hardware watch dog reset
      strcpy_P(buff, PSTR("Hardware Watchdog"));
    } else if (resetInfo.reason == REASON_EXCEPTION_RST) { // exception reset, GPIO status won’t change
      strcpy_P(buff, PSTR("Exception"));
    } else if (resetInfo.reason == REASON_SOFT_WDT_RST) { // software watch dog reset, GPIO status won’t change
      strcpy_P(buff, PSTR("Software Watchdog"));
    } else if (resetInfo.reason == REASON_SOFT_RESTART) { // software restart ,system_restart , GPIO status won’t change
      strcpy_P(buff, PSTR("Software/System restart"));
    } else if (resetInfo.reason == REASON_DEEP_SLEEP_AWAKE) { // wake up from deep-sleep
      strcpy_P(buff, PSTR("Deep-Sleep Wake"));
    } else if (resetInfo.reason == REASON_EXT_SYS_RST) { // external system reset
      strcpy_P(buff, PSTR("External System"));
    } else {
      strcpy_P(buff, PSTR("Unknown"));
    }
    return String(buff);
}


- Fri Feb 26, 2016 7:26 pm #41963 there has been a lot of problems with this.
For some time (sdk 1.1 ???) deepsleepwakeup was indeed reported as 6,
then for some (sdk 1.3 ???) time it didn't work at all
with the latest version (sdk 1.5) it is now correctly reported as 5

Unfortunately, this is not true ! deepSleep awake is 5 ! - See more at: viewtopic.php?f=32&t=8411&start=4#sthash.4hwJAvXx.dpuf

Yes, I know. That was what I expected. But I got "6" everytime.
I'm using the Arduino IDE 1.6.5 with ESP Ver 2.0.0
I checked the Esp.cpp and found and in my version the getResetReason(void) was missing.
I copied the Esp.cpp and Esp.h from https://github.com/esp8266/Arduino/tree/5e19757d54582c57342bfb0685248d791b97d372/cores/esp8266 which seems to be a newer version, but no change

Code: Select allStart...
ResetInfo.reason = 6     <-------- this is after hw reset
going to sleep now...
....
Start...
ResetInfo.reason = 6      <------- this after deep sleep.
going to sleep now...


I used this code

Code: Select allextern "C" {
#include "user_interface.h"
}

void setup() {
  rst_info *rsti;
  Serial.begin(115200);
  rsti = ESP.getResetInfoPtr();
  Serial.println("\r\nStart...");
  Serial.println(String("ResetInfo.reason = ") + rsti->reason);
}

// the loop function runs over and over again forever
void loop() {
  Serial.println("going to sleep now...");
  system_deep_sleep_set_option(0);
  system_deep_sleep(10000000);            // deep sleep for 10 seconds
  delay(1000);
}
