program arduino using HC05

I followed following tutorials.

  1. Arduino Project Hub
  2. http://www.instructables.com/id/Program-an-Arduino-Wireless-Over-Bluetooth/
  3. https://sites.google.com/site/wayneholder/inexpensively-program-your-arduino-via-bluetooth

I got the same error in all the projects.
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
How can I resolve this error ?
