Invalid HW cmd: 1018039319

I just created a sketch from
And didn’t change a thing from that forum but I’m still getting the error in the serial monitor-
Invalid HW cmd: 1018039319
the whole text in the serial monitor includes-

[169346] Connecting...
[169549] Ready (ping: 85ms).
[183574] Invalid HW cmd: 1018039319

And just repeats those 3 lines of text
the whole code consists of-

  Download latest Blynk library here:

  Blynk is a platform with iOS and Android apps to control
  Arduino, Raspberry Pi and the likes over the Internet.
  You can easily build graphic interfaces for all your
  projects by simply dragging and dropping widgets.

  Blynk library is licensed under MIT license
  This example code is in public domain.

  Note: This only works on Android!
        iOS does not support Bluetooth 2.0 Serial Port Profile
        You may need to pair the module with your smartphone
        via Bluetooth settings. Default pairing password is 1234

  Feel free to apply it to any other example. It's simple!

  NOTE: Bluetooth support is in beta!

  You can receive x and y coords for joystick movement within App.

  App project setup:
    Two Axis Joystick on V1 in MERGE output mode.
    MERGE mode means device will receive both x and y within 1 message

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "21d19d7c7f8245c9ae9b00f9a2c8ebd1";

SoftwareSerial SerialBLE(10, 11); // RX, TX

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

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

void setup()
  // Debug console

  Blynk.begin(SerialBLE, auth);

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

void loop()

Im using bluetooth HC05 and an arduino Mega and attempting to use the joystick to control a H-Bridge for the wheels (haven’t added that yet)

May not be related to your error, which I suspect happens whenever you move the joystick?.. but with the Mega, I recommend you use one of its three auxiliary Hardware serial ports (instead of SoftSerial) for your BLE connection, for faster and more reliable connections.

Switch to that and see if it helps.
