I have what is probably a simple question that I just so happen to have not found a definitive answer to. I am wiring up a bluetooth antenna (BlueSmirf RS-SMA) to control my robot wirelessly. I know I have to wire up power (VCC), ground (GND), transmit (TX-0), and receive (RX-1). My question is do I need to wire up RTS-0 and CTS-1 in any fashion? I cannot seem to find anything to indicate yes or no.
