Bluefruit LE UART Friend on Arduino Uno

It's just on my laptop for now. Will be from a 9v wall socket adapter as soon as i'm finished.
I have another question though.
I got it working, and I can chat back and forth, but what variable is my phone texts? (RX) I am trying to do something like:

If (phoneinput == "test") {
Serial.println("Yay, it works");
}

What do I put in the statement? It seems like ble.buffer would be the one, as it says "Serial.println(ble.buffer);", but I can't seem to get it to work.
