Arduino Blue to Blynk

Need Help With My Project
1

Arduino MEGA ,with HM-10 bluetooth connecting to iphone.
I have the “arduinoblue” setup connecting with any problem from hardware serial2 port


#include <ArduinoBlue.h>

const unsigned long BAUD_RATE = 9600;

int prevThrottle = 49;
int prevSteering = 49;
int throttle, steering, sliderVal, button, sliderId;

// See: https://www.arduino.cc/reference/en/language/functions/communication/serial/
ArduinoBlue phone(Serial2);

// Setup code runs once after program starts.
void setup() {
    // Start serial communications.
    // The baud rate must be the same for both serials.
    Serial.begin(BAUD_RATE);
    Serial2.begin(BAUD_RATE);
    
    delay(100);

    Serial.println("setup complete");

I have problem connecting to blynk with the code below, what i may be doing wrong?


#define BLYNK_PRINT Serial


#include <BlynkSimpleSerialBLE.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "HRbgs53z9956PosfEmezwGtY6zLZCNw0";

BLYNK_WRITE(V1) {
  int x = param[0].asInt();
  int y = param[1].asInt();

  // Do something with x and y
  Serial.print("X = ");
  Serial.print(x);
  Serial.print("; Y = ");
  Serial.println(y);
}

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

  Serial2.begin(9600);
  Blynk.begin(Serial2, auth);

  Serial.println("Waiting for connections...");
}

void loop()
{
  Blynk.run();
}

I am using the ios app Blynk.
Also a working hardware serial example on mega will help a lot. Thanks in advance.

managed to get something from serial monitor. Packet too big ???
any ideas?

@kiteklan 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:

Thanks for the advise , corrected.

Blynk is totally not usefull for Turkey, there is long pings and timeouts for Bluetooth.
can not control the device

I’d say that there are many Blynk users who disagree with you…

The ping time to the server is probably more about your WiFi, local internet connection and ISP than anything else.
The nearest Blynk cloud server is in Frankfurt, which is around 3,000km, so with a good internet connection the ping times should be very good.

Bluetooth timeouts are very much a hardware and physical distance to the phone issue - unless you have something else that is trying to connect to your HM-10 that’s causing an issue.

If your internet connection is poor then you could always set-up a local Blynk server on your network.
