Soft WDT reset - ESP 01

Projects Programming
1

My name is Ernesto, i’m working on a project with module esp01, the idea is to have a door alarma with magnetic sensor. In the developing phase I’ve runned into a Soft WDT reset issue.

This is my code:

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>
#include <UniversalTelegramBot.h>
#include <ArduinoJson.h>

// Wifi network station credentials
#define WIFI_SSID "Imperio1"
#define WIFI_PASSWORD "Sistemas20"
// Telegram BOT Token (Get from Botfather)
#define BOT_TOKEN "5081397447:AAGoQ0SzdLuZHgQAcHOiEhPgT6oDxCzYSBo"
#define CHAT_ID "-680973127"

X509List cert(TELEGRAM_CERTIFICATE_ROOT);
WiFiClientSecure secured_client;
UniversalTelegramBot bot(BOT_TOKEN, secured_client);

const unsigned long BOT_MTBS = 1000; // tiempo medio entre mensajes escaneados
unsigned long bot_lasttime;          // última vez que se realizó el escaneo de mensajes
const int sensorPuerta = 2;
int abierto = 0;
int cerrado = 0;
bool estadoAlarma = 0;
//String chat_id;


void setup() {
  Serial.begin(115200);
  Serial.println();

 // attempt to connect to Wifi network:
  Serial.print("Connecting to Wifi SSID ");
  Serial.print(WIFI_SSID);
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  secured_client.setTrustAnchors(&cert); // Add root certificate for api.telegram.org
  while (WiFi.status() != WL_CONNECTED)
  {
    Serial.print(".");
    delay(500);
  }
  Serial.print("\nWiFi connected. IP address: ");
  Serial.println(WiFi.localIP());

  Serial.print("Retrieving time: ");
  configTime(0, 0, "pool.ntp.org"); // get UTC time via NTP
  time_t now = time(nullptr);
  while (now < 24 * 3600)
  {
    Serial.print(".");
    delay(100);
    now = time(nullptr);
  }
  Serial.println(now);
  bot.sendMessage(CHAT_ID, "📡 Wifi Conectado!!", "");

  pinMode(sensorPuerta, INPUT);
  
}

void loop()
{
   if (millis() - bot_lasttime > BOT_MTBS)
  {
    int numNewMessages = bot.getUpdates(bot.last_message_received + 1);

    while (numNewMessages)
    {
      //Serial.println("Llego un mensaje!!");
      handleNewMessages(numNewMessages);
      numNewMessages = bot.getUpdates(bot.last_message_received + 1);
    }

    bot_lasttime = millis();
  }

  int lectura = digitalRead(sensorPuerta);
  delay(100);
  if (estadoAlarma == 1 && lectura == 0){
    abierto ++;
    imprimeAbierto(abierto, lectura);
    cerrado = 0;
  }else if(estadoAlarma == 1 && lectura == 1){
    //Serial.println(lectura);
    abierto = 0;
    cerrado ++;
    imprimeCerrado(cerrado, lectura);
  }
  
}


void handleNewMessages(int numNewMessages)
{
  Serial.print("handleNewMessages ");
  Serial.println(numNewMessages);

  for (int i = 0; i < numNewMessages; i++)
  {
    String chat_id = bot.messages[i].chat_id;
    String text = bot.messages[i].text;

    String from_name = bot.messages[i].from_name;
    if (from_name == "") from_name = "Guest";

    if (text == "/armado"){
      estadoAlarma = 1;
      Serial.print("Panel de alarmas: ARMADO - ");
      Serial.println(estadoAlarma);
      bot.sendMessage(chat_id, "📟 Panel de alarmas: ✅ ARMADO", "");
    }else if (text == "/desarmado"){
      estadoAlarma = 0;
      Serial.print("Panel de alarmas: DESARMADO - ");
      Serial.println(estadoAlarma);
      bot.sendMessage(chat_id, "📟 Panel de alarmas: ❌ DESARMADO", "");
    }else{
      Serial.print("Comando No reonocido...");
      bot.sendMessage(chat_id, "Comando No reconocido 🚫", "");
      }
      
          
  }
}

void imprimeAbierto(int abierto, int lectura){
  if (abierto < 2){
    Serial.print("Puerta Abierta - ");
    Serial.println(lectura);
    bot.sendMessage(CHAT_ID, " Puerta Abierta 🚪🟢", "");
  }        
}

void imprimeCerrado(int cerrado, int lectura){
  if (cerrado < 2){
    Serial.print("Puerta Cerrada - ");
    Serial.println(lectura);
    bot.sendMessage(CHAT_ID, " Puerta Cerrada 🚪🔴", "");
  
    }
}

This is the error

handleNewMessages 1
Panel de alarmas: ARMADO - 1

You got a software watchdog reset, what about the while() inside the loop() function?

Try to put a delay(1) inside and check the result.

This is blocking code, and I suspect that this is the root of the problem.
Try putting a yield(); into the while loop to reset the WDT.
