I just met this article herehttp://m.instructables.com/id/Arduino-AND-Bluetooth-HC-05-Connecting-easily/?ALLSTEPS
It suggests using software serial library and use some other pins as TX/RX instead of the original ones(pin0,pin1) This would lead us on a better bluetooth perfomance and no more trouble..
Any one knows something more about this?
It is nonsense and is more likely to lead to the exact opposite. I can't say I'm surprised to hear this, it seems pretty typical of the junk the comes from instructables.
If you have not yet used bluetooth, you might find the following background notes useful

Well ok 8) 8)
No i've used Bluetooth many times, i just came out to this and i thought i should ask..
By the way on the link you posted there was a simple schematic and showed a level shifting on the TX line , is that really necessary ?
As we know HC-06 operates on 5v..

Once you know the principle, you can't say it isn't. It can't be a bad idea, but I have never done it, and I've never had a problem.
