NodeMCU v3 Reset

[konig87nikkinakki]

Hi,
i receive this error (and reset) on serial when i run the following code:

Exception (3):

I would like to turn off and on a led with telegram bot, so this is the code (it's not complete but it crashes so i cannot continue coding):

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

int led = 2;
 
const char* ssid = "MySSID";
const char* password = "MyWPAkey";
const char BotToken[] = "mybot:token";

WiFiClientSecure net_ssl;
TelegramBot bot (BotToken, net_ssl);


void setup() {
  pinMode(pin, OUTPUT);
  Serial.begin(9600);
  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 off 
  Serial.println("Led OFF");
  delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED on 
 Serial.println("Led ON");
  delay(1000);               // wait for a second
 message m = bot.getUpdates(); // Read new messages
//it wait a lot after Led On and then errors
//here i want to continue coding but i cannot because it crashes so it doesnt worth it.
delay(1000);

}

i m using nodeMCU v3, with ESP8266MOD chip on it, i tried with 8v input and 2200uF big capacitor, it crashes. i tried blinking sketch with serial.println inside, it doesnt crashes. seems to crash only when using message m = bot.getUpdates(); or other using BOT library. i also tried to upgrade firmware but i don't know if i chose the last or correct one. i have another NodeMCU v3 board, i tried (without upgrading firmware) and it still crashes. i don t know what else to try to do.

it connects to wifi at
WiFi connected
172.31.189.167
it's correct ip of my net. i also tried to change network, it still crashes: it's not a wifi problem but (i think) a bot telegram library problem.

Can someone please help me?
Thanks a lot!

I am getting the same on a normal NodeMCU ESP-12E...
The example EchoBot 8266 fails completely and resets the device forever. Useless.

internet is good because we can share problems and SOMETIME solve it.
i think it will be hard to solve it. new year's eve is near, i propose to drink a lot and burn nodemcu into Etna's vulcano (in Lord of Rings' style).

[fmarzocca]

The reset is generated from the getUpdates() function.

probably, if i dont use it (only blinking) it never crashes. are they other TelegramBot library that could i use? please if you find solutions write here, i ll do the same.

Accepted suggestion! :-)

..this is not fair.... look on google.

i'm trying to use Gianbacchio's library, looks more professional, but i have another issue: it doesnt connect to my wifi, even if i set up with my SSID and WPA key (i tried to change to WPA2 or WEP).

please tell me if it works with your NodeMCU. I'm trying Example "echoBot".

HEY I SOLVED!!!!
here what i m using:

1. arduino ide 1.8.6
2. Strumenti --> Gestione Schede --> ESP8266 old version 2.3.0 installed (OLD VERSION!)
3. CasaJasmina Telegrambot v1.2.5 (today it's the last version)
4. CasaJasmina need ArduinoJson library by Benoit Blanchon to work, NOT THE LAST ONE, i m using v5.13.1

if you installed 2) ESP8266 newer version, you have to

1. uninstall Arduino (c:\users\user\Document\Arduino\Libraries will not be deleted, so don't worry!)
2. go to %appdata% --> Local --> Arduino15 and DELETE that folder (it contains ESP8266 new version, you have to delete)
3. install arduino ide 1.8.6
4. install new shield ESP8266 and choose 2.3.0 version like mine.

Now i m running this code and it works (no reset)

/*
  EchoBot on ESP8266

  This example shows how to program a Telegram Bot
  that echoes your messages.

  This example code is in the public domain.

*/

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

// Initialize Wifi connection to the router
const char* ssid  = SECRET_SSID;
const char* password = SECRET_PASS;


// Initialize Telegram BOT
const char BotToken[] = SECRET_BOT_TOKEN;

WiFiClientSecure net_ssl;
TelegramBot bot (BotToken, net_ssl);


void setup() {

  Serial.begin(9600);
 // while (!Serial); // Wait for the Serial monitor to be opened

  // attempt to connect to Wifi network:
  Serial.print("Connecting Wifi: ");
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");


  bot.begin();

}

void loop() {
 
    message m = bot.getUpdates(); // Read new messages
    if ( m.chat_id != 0 ){ // Checks if there are some updates
      Serial.println(m.text);
      bot.sendMessage(m.chat_id, m.text);  // Reply to the same chat with the same text
    } else {
      Serial.println("no new message");
    }

}

that is EXAMPLE: EchoBot-ESP8266.ino into CasaJasmina Telegrambot v1.2.5 Library. Of course i had to put my data (SSID, WPA, token).
Let me know if you have problems.
Tomorrow i ll look for a better stable library ;-)
keep in touch!

[konig87nikkinakki]

With those library and settings that i ve written to you, you can program this:
https://www.instructables.com/id/Smart-House-Telegram-Bot-With-Nodemcu-esp8266-Rela/
and it works (NOTE: image in the guide is wrong connecting Rele and Led, please only use to read code and try to run it, it will work with these settings).

[fmarzocca]

I am using another library, with no need to downgrade board manager! 2.3.0 is a very old core for esp8266

Ok, can you please tell me what's your library name? i d apprieciate.

[fmarzocca]

We cannot use this support thread as a chat. I told you, it's not fair. This is a support ticket for this Library.

certo, come no.
Thank you.

accept this method in your code

WiFiClientSecure client;
TelegramBot bot (BotToken, client);
void setup() {

client.setInsecure();
