Serial not working

Using Arduino Programming Questions
#1

I have Arduino IDE version 1.0.5.

I have connected my Arduino Leonardo through USB to the PC.
I have connected to my Arduino a Xbee module at pins 2 and 3 with SoftwareSerial.
I also have a Xbee module connected to the PC.
Both of the XBee modules are set to API mode 2 (I don’t know if this matters).

This is the code I’m running:

#include <SoftwareSerial.h>

char buffer[256];
SoftwareSerial xbee(2,3);

void setup()
{
  xbee.begin(9600);
  xbee.listen();
  Serial.begin(9600);
}

void loop()
{
  if(xbee.available())
  {
    xbee.readBytes(buffer,xbee.available());
    Serial.println(buffer);
  }
}

Both the Xbee modules notify serial messages through their LEDs. Both of them were checked to see if they are operational.

The question is simple: why doesn’t the serial port (on 2 and 3 pins) work? When I attach to xbee Serial1 port, it does work, but when I use SoftwareSerial, it doesn’t.

#2

Not sure because I never used SoftwareSerial but:

Not all pins on the Leonardo support change interrupts,
so only the following can be used for RX:
8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).

You were right, my friend. It worked. I would have never thought about this.

Thanks
