Problem Description

I have test example ESP8266\ConfigFile, and it not work. Compilation and download OK, but fail in runnig mode. I have Continusly hardware reset and I never see Serial Message other than reset error message. I have test with Generic ESP12 and NodMCU1.0 and have same problem.
I have last version of ArduinoJson Library 6.13.0 and i have select Flash size 4MB (FS: 2MB/OTA: 1019KB)

MCVE Sketch

Same than Example ESP8266\ConfigFile . No modifications.

Hoops!! It's a mistake all work fine. I have make error by add : while(!Serial); before Serial.begin than after to wait and see sketch message at start when i open serial monitor. This invertion creat reset cyclicly.
Sorry for false alarm.

Hi, please don't disappear i have the same problem, but it crashes when i try to read message from Telegram Bot. here the code:

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#include <TelegramBot.h>

#define LED0 3 //D3
#define LED1 1 //D10
#define LED 2 //D4
#define LED3 10 //SD3
#define DS18B21 0  //D9

const char* ssid = "SSID";
const char* password = "wpa-key";
const char BotToken[] = "token:mytoken";

WiFiClientSecure net_ssl;
TelegramBot bot (BotToken, net_ssl);


void setup() {



  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
     delay(500);
     Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println(WiFi.localIP());
  bot.begin();  
}




void loop() 
{  

digitalWrite(LED, HIGH);   // turn the LED on (HIGH is the voltage level)
  Serial.println("Off");
 delay(1000);               // wait for a second
  digitalWrite(LED, LOW);    // turn the LED off by making the voltage LOW
  Serial.println("On");
  delay(1000);               // wait for a second
 message m = bot.getUpdates(); // Read new messages
delay(1000);
}

It crashes with the same code of yours, after blinking led.
if i cancel
message m = bot.getUpdates(); // Read new messages
it never crashes.

I tried with +8v and big capacitor in Vin, i tried with another ESP (i was afraid it was bad working).
I m using NodeMCU v3 with "esp8266mod" on it.

i receive this error:

can you please help me?

[BOBILLIER]

Sorry but I can't help you. It's not because we see same error message, than we have same problem.
Like i have said before, my problem come from a "While(!Serial);" instruction who are place before Serial.begin(); I don't see this in your program. Good luck.

[konig87nikkinakki]

can you please try to run it into your nodemcu and tell me if it happens to you?

I get the same error. I connected the LED strip through the mosfet, but the reset starts after the pinMode(5, OUTPUT) on any of the pins to which the tape is connected (there is no such error on other pins)
