Hello everyone:
I have 2 boards (1 arduino uno and 1 mega). And I want to connect them using HC-05 bluetooth module, setting uno as master and mega as slave, but I cannot find any examples of how to connect them =( (just examples of how to connect arduino to computer or android), but nothing about two arduinos between them. Can you help me? :~ Thanks! 
Bluetooth is serial, so a regular serial setup and connection should work. I would know, I do it all the time with my robot and controller (Uno and Mega).
If you can read and print data to/from the serial monitor with one, you can get the two Arduino to talk to each other. The only thing that may be an issue is range. Bluetooth can only go ~30 ft, depending on your surroundings.
Start with simply reading data to and from the serial monitor, get that to work, then substitute the computer with a second Arduino with the same code.
