Have you had a look over this?
// Debug console
// Blynk will work through Serial
// 9600 is for HC-06. For HC-05 default speed is 38400
// Do not read or write this serial manually in your sketch
It means your hardware serial pins (Rx,Tx) are connected to HC-05 (Tx,Rx) pins respectively. Not the software serial pins as they are for debugging only.
Pay attention to HC-05 Rx<---->Arduino Tx connection must pass by voltage divider since it is a 3.3v chip.
The photo is for demonstration. Remember that you need to wire the hardware serial pins to your Bluetooth module.
I tested HC-05 over a baudrate of 9600 and it is working as well.
