Arduino Nano + iPhone 11 + HM-10 "Packet too big"

Need Help With My Project
1

Hello, I trying to connect Arduino Nano with my iPhone through HM-10 Bluetooth connection, but I only have an error, “Packet too big”

  • Arduino Nano
  • iPhone 11 IOS 13.4.1
  • Blynk server 0.6.1

#define BLYNK_PRINT Serial
#define BLYNK_DEBUG

#include <SoftwareSerial.h>
SoftwareSerial SwSerial(10, 11); // RX, TX
    
#include <BlynkSimpleSerialBLE.h>
#include <SoftwareSerial.h>

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

SoftwareSerial SerialBLE(8, 9); // RX, TX

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

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

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

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!
}

Conected in this way:

Nano pin D9 -> HM10 RX
Nano pin D8 -> HM10 TX
Nano pin 3v3-> HM10 VCC
Nano pin GND->HM10 GND

I have changed pins.

#define BLYNK_PRINT Serial
#define BLYNK_DEBUG

#include <SoftwareSerial.h>
SoftwareSerial SwSerial(10, 11); // RX, TX
    
#include <BlynkSimpleSerialBLE.h>
#include <SoftwareSerial.h>

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

SoftwareSerial SerialBLE(2, 3); // RX, TX

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

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

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

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!
}

SORRY, IT FAILS AGAIN.
I didn’t anything and I have the same errors.

Why do you have this twice:

and a definition for a SoftwareSerial port that’s not used?

Pete.

#define BLYNK_PRINT Serial
//#define BLYNK_DEBUG
#define BLYNK_USE_DIRECT_CONNECT

#include <SoftwareSerial.h>

#include <BlynkSimpleSerialBLE.h>

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

SoftwareSerial SerialBLE(2, 3); // RX, TX

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

  SerialBLE.begin(19200);
  Blynk.begin(SerialBLE, auth);

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

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

}

this is my code.

The same error…

People generally say that you’ll get problems when using SoftwareSerial at baud rates above 9600.

I have changed and same error.
