Need help to send serial data from arduino to XBee and to another XBee wirelessly?

Question

I try to send serial data RPM to XBee series1 and then from XBee to another XBee wirelessly in API with Escapes Mode. I think I have to send the data Frame.But not very sure. Any help?

Following is the code to read RPM and send to XBee?

#include <XBee.h>
#include <SoftwareSerial.h>
/* Serial communication with Xbee.
On Arduino pin 9 is Rx connect to Xbee Tx, 
pin 8 is Txconnect to Xbee Rx*/
SoftwareSerial xbeeSerial(9, 8); // RX, TX

XBee xbee = XBee();

int pin = 7;  //7
float rpm;
float duration;
float y;

unsigned long val,time;
float rps;
float read_rpm;



uint8_t start_data[] = { 0x7E, 0x00, 0x50, 0x01, 0x01, 0xff, 0xff,0x00, 0x05, 0x00,0x01,0x03, 0x84, 0x00 };

void setup() 
{
  Serial.begin(9600);
  pinMode(pin, INPUT);
  Serial.println("I am ready to send some RPM!");
  xbeeSerial.begin(9600);
  time = millis();
}

void loop()
{

void loop()// run over and over
{
 val =  pulseIn(pin, LOW,70000000);

 duration=(float)val/1000000.00;
 rps= 1.00/duration;
rpm=60.00*rps;

/* Sending float to Xbee
Float is 4 byte size*/
serialFloatPrint(rpm);

int floatToInt = (int)rpm;

/* To send INT to XBEE
Int is 2 byte size*/
xbeeSerial.write(highByte(floatToInt));
xbeeSerial.write(lowByte(floatToInt));

  Serial.write(0x03);

  delay(2000);
}

void serialFloatPrint(float f) {
  byte * b = (byte *) &f;

  //xbeeSerial.print("f:");
  xbeeSerial.print(b[0]);
  xbeeSerial.print(b[1]);
  xbeeSerial.print(b[2]);
  xbeeSerial.print(b[3]);
  /* DEBUG */
  Serial.println();
  Serial.print(b[0],BIN);
  Serial.print(b[1], BIN);
  Serial.print(b[2], BIN);
  Serial.println(b[3], BIN);
  //*/
}
}

You are using it as in non-API mode when data are passed to Xbee wireless transparently. To use Xbee in API mode use e.g. Xbee-Arduino library.
