HC-06 Bluethoot communication During this week i purchased two hc-06 bluethoot module for arduino with the purpose of maintain a stable bluethoot connection between two arduino devices. Most people use hc-05 and hc-06 togheter so my question is if i can make a connection without hc-05 module.
No.

What you have is two slave devices and you need a master in order to initiate the Bluetooth communication with the slave. So, either you need two HC-05 Or 1* HC-05 and 1* HC-06.
