How To Rename BLE device

I am having problems with renaming my BLE device. Here is the code I am using to rename it.

void setup()
{
Serial.begin(9600);
delay(5000);

Serial.print(“AT+NAME= Dank Tank”); //<<<<This is renaming it

delay(5000);

SerialBLE.begin(9600);
Blynk.begin(SerialBLE, auth);
Serial.println(“Waiting for connections…”);
}

What does this have to do with Blynk?
