Connecting 2 Arduino boards via Bluetooth

I have a problem related to connecting 2 Arduino board via Bluetooth using HC-05 modules. I followed the instruction in this website http://blog.zakkemble.co.uk/getting-bluetooth-modules-talking-to-each-other/ and i succeed in connecting two modules. But when i tried to use these two modules with the Uno boards, it didn’t work. Here is my code:

The code for Arduino UNO (HC-05 master):

#include <SoftwareSerial.h>

long unsigned starting = millis();
const int rxPin = 10; //SoftwareSerial RX pin, connect to JY-MCY TX pin
const int txPin = 12; //SoftwareSerial TX pin, connect to JY-MCU RX pin
SoftwareSerial mySerial(rxPin, txPin);
const int led_pin = 13;
void setup() {
// put your setup code here, to run once:
mySerial.begin(9600);
pinMode(led_pin,OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
long unsigned ending = millis();
if (ending - starting > 2000)
{
starting = millis();
mySerial.write(‘t’);
digitalWrite(led_pin,HIGH);
delay(500);
digitalWrite(led_pin,LOW);
delay(500);
}
}

The code for Arduino UNO (HC-05 slave):

#include <SoftwareSerial.h>

long unsigned start = millis();
const int rxPin = 10; //SoftwareSerial RX pin, connect to JY-MCY TX pin
const int txPin = 12; //SoftwareSerial TX pin, connect to JY-MCU RX pin
SoftwareSerial mySerial(rxPin, txPin);
const int led_pin = 13;
void setup() {
// put your setup code here, to run once:
mySerial.begin(9600);
pinMode(led_pin,OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
char value;
if (mySerial.available())
{value = mySerial.read();}
if (value == ‘t’)
{
digitalWrite(led_pin,HIGH);
delay(500);
digitalWrite(led_pin,LOW);
delay(500);
}
}

I saw that the LED in the Arduino master board was on for after each 2s, but the LED in Arduino slave board wasn’t. Can you help me? Sorry for my bad English. Thank you very much!

If you are not using the HardwareSerial pins for communication, why are you not using them to talk to the PC? Debug by guessing sucks.
