The SoftwareSerial library can configure other digital pins on your Arduino so that they can be used for serial communication. This is where Arduino's SoftwareSerial library comes in.

If you want your Arduino program to print some output while also talking to RVR+/RVR, you may find that using the Arduino's built-in hardware for serial communication gives you messy results: Getting NORDIC main application version. This demo will walk you through how to set up a Software Serial connection using Arduino's SoftwareSerial library.
