we use barcode reader with usb. Connectig it with aduino(UNO).
 All we want to realizing is next.
 At first, scanning a barcode and its information is save in variable A.
 and send it to the second computer with bluetooth.
 Doing this process several times, and fnally,
 displaying all information in second computer.


 For this, we made two programs.
 One is for senging information with BT, and the other is reading barcode numbers with scanner.

 we wanted to intergrate it, but it is too hard for us.

 please help...!!

 This is specific code..!

and BT communication code is here.
블루투스



#include <softwareserial.h>

SoftwareSerial BTSerial(2, 3 ); //Connect HC-06 TX,RX()
void setup()
{
Serial.begin(9600);
BTSerial.begin(9600);
}
void loop()
{
if (Serial.available())
BTSerial.write(Serial.read());
}

How can I intergrate those two codes...!
