Making two arduinos talk together via Bluesmurf

i have been struggling problem times now.
i have bluesmurf (silver) modules, , want able send numbers 1 arduino other one. have been searching long , didnt find soloution.


what have right now, 2 bluesmurf connected , show green light when both online

char data = 0;            //variable storing received data
void setup()
{
    serial.begin(9600);   //sets baud serial data transmission                               
    pinmode(13, output);  //sets digital pin 13 output pin
}
void loop()
{
   if(serial.available() > 0)      // send data when receive data:
   {
      data = serial.read();        //read incoming data & store data
      serial.println(data);          //print value inside data in serial monitor
      serial.println("\n");       
      if(data == '1')    {          // checks whether value of data equal 1
         digitalwrite(13, high);   //if value 1 led turns on
         serial.println("on");
      }
      else if(data == '0') {       //  checks whether value of data equal 0
         digitalwrite(13, low);    //if value 0 led turns off
         serial.println("off");

#define button 8

int state = 20;
int buttonstate = 0;
void setup() {
  pinmode(button, input);
  pinmode(9, output);
  serial.begin(9600); // default communication rate of bluetooth module
}
void loop() {
 if(serial.available() > 0){ // checks whether data comming serial port
    state = serial.read(); // reads data serial port
 }
 
 // reading button
 buttonstate = digitalread(button);
 if (buttonstate == high) {
   serial.write('1'); // sends '1' master turn on led
   digitalwrite(13, high);
 }
 else {
   serial.write('0');
   digitalwrite(13  , low);
 } 
}






anyone knew solution ?
