Bluetooth HC-05 or HC-06


I need a bluetooth connection between the arduino and an android device. Now, I don’t now which model (HC-05 or HC-06) I should use.

I know, that the HC05 can be master and slave and the HC-06 only can be a slave.

But which bluetooth shield do I need? The arduino don’t need to conenct to the android device automatically, so is the HC-06 module ok? It would be ok when I connect to the arduino from the android phone manually.

Thanks a lot!

No idea?
