how can i send a specific code from hc05 to another hc05 , not all serial.print just a small code from it
Your post is incoherent, but the probable answer is you can't. The HC-05 is a plain-vanilla SPP device used to transmit data.
Code can be data, and looks that way to an HC-05, but it would appear that that is not what you want.
you could have one HC-05 act as a Bluetooth master and the other as a Buetooth slave ??
