I've connected the bluetooth rx and tx pins to arduino rx and tx, respectively. Do I need to declare the pins as output/input
or is there some native protocol that allows the bluetooth module to access the serial already?
Do I always need to use rx and tx for signal transmission?
Or are any of the digital pins applicable?
Would I need to refine/use a pre-amplifier when transmitting the signal?
