Problem Description

Hey guys, I'm new to this world so please excuse me If I'm asking dumb question. I tried to find a solution but here I am here asking :).

I'm using Node MCU 8266 L0L1n ESP-12E Module type and I'm trying to put it into Deep Sleep. Now I don't have anything connected to the board.

Simply only RST to D0 since that's what I was able to read. I need to connect it so it will reset the board after the time of deep sleep.

My code is really basic :

void setup () { Serial.begin(74880); delay(1000); pinMode(LED_BUILTIN, OUTPUT);

Serial.println("Im awake"); digitalWrite(LED_BUILTIN, HIGH); delay(3000); digitalWrite(LED_BUILTIN, LOW); delay(1000); Serial.println("im sleeping"); u32 SLEEP = 30E6; ESP.deepSleep(SLEEP, WAKE_RF_DISABLED); }

void loop(){}

So the first time it works nice I can see everything in the serial consoled and also the board blue lamp turns on and off. After that it's printing " I'm sleeping " and after 30 seconds the board indicates restart but the console is showing

Debug Messages

ets Jan 8 2013, rst cause:2, boot mode:(3,6)

After that nothing happens.

If I restart manually from the RST button it does the same. It works 1 time before it goes to sleep.

So I read a lot and this rst cause:2, boot mode:(3,6) shows that it's getting out of deep sleep. Atleast of what I was able to find but why it's not executing setup() again and continue doing that ?

Can anyone give me a hand? I have 3 boards and all 3 does the same as above ^. Is there any other way to put this board in deep sleep mode for power consuming?
