please help me! I can’t connect my Arduino Mega to blynk, even though my source code Arduino already has ‘Done Uploading’. and the problem is:

I connecting Arduino Mega 2560 to ESP8266 ESP01 which upgraded version. anybody know how to solve my problem?:frowning:

Hi, you need to post your code . . .

You also need to provide detailed information about how you have connected your Arduino Mega and ESP-01 together.

i connected Arduino Mega 2560 to ESP01.
ESP01 pin --> Arduino Mega
TX --> RX
RX --> TX
VCC --> 3.3V
CH_EN --> 3.3V
GND --> GND

do you know my problem? i can’t find it :frowning:

The TX and RX pins on the Mega are best used for serial debugging, so you’d be better off using one of te other three serial ports on the Mega for your connection to the ESP-01.
Read this for more info (Yes, it’s about connecting a Bluetooth module rather than an ESP-01, but the same issues remain):

You’ll obviously need to amend the sketch that you upload to the Mega (which @Bill_Donnelly has asked you to post, but which you haven’t) .

please help me! I can’t connect my Arduino Mega to blynk, even though my source code Arduino already has ‘Done Uploading’. the source code is:



#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "q7uYUIAuDGELS0ImHQCvvVSnir8aLeGZ";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "Tembok Wifi";
char pass[] = "1sampai8";

// Hardware Serial on Mega, Leonardo, Micro...
#define EspSerial Serial1

// or Software Serial on Uno, Nano...
//#include <SoftwareSerial.h>
//SoftwareSerial EspSerial(17, 18); // RX, TX

// Your ESP8266 baud rate:
#define ESP8266_BAUD 9600

ESP8266 wifi(&EspSerial);

void setup()
{
  // Debug console
  Serial.begin(9600);

  // Set ESP8266 baud rate
  EspSerial.begin(ESP8266_BAUD);
  delay(10);

  Blynk.begin(auth, wifi, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, wifi, ssid, pass, "blynk-cloud.com", 80);
  //Blynk.begin(auth, wifi, ssid, pass, IPAddress(192,168,1,100), 8080);
}

void loop()
{
  Blynk.run();
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!
}    ```



 and the problem is:

@vikalaeli please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:

I’ve merged this into the previous topic you created on this subject- please don’t keep creating new topics on the same subject otherwise your forum account will be suspended.

I’ve already told you what the first step towards resolving this issue is, but you’ve ignored that advice. Is there any reason why?

Pete.

Please change your ESP buadrate to 9600 if you’re using the sofwtare serial
