Step 9: Solder Leads to the Bluetooth Module

Solder a length of wire between the CTS-I and RTS-O pins of the BlueSMiRF to short them. These are used for hardware flow control, which we don't need.

Cut four wires (or better yet, a ribbon cable) and solder them to the VCC, GND, TX-O and RX-I pins of the BlueSMiRF. Again, you can leave these long and cut them to size later, when you get an idea for how much space you are working with.

Bluetooth! Snazzy. I used some spare speaker wire (the kind thats two wires stuck together) that was left over from installing my stereo.
