transmitter module

#include <VirtualWire.h>
//Grove - 315(433) RF link kit Demo v1.0
//connect the sent module to D2 to use  
#include <VirtualWire.h>
int RF_TX_PIN = 2;
void setup()
{
  vw_set_tx_pin(RF_TX_PIN); // Setup transmit pin
  vw_setup(2000); // Transmission speed in bits per second.
} 
void loop()
{
  const char *msg = "hello";
  vw_send((uint8_t *)msg, strlen(msg));  // Send 'hello' every 400ms.
  delay(400); 
}

receiver module

//Grove - 315(433) RF link kit Demo v1.0
//connect the receive module to D2 to use ..
#include <VirtualWire.h>
int RF_RX_PIN = 2; 
void setup()
{
  Serial.begin(9600);
  Serial.println("setup");
  vw_set_rx_pin(RF_RX_PIN);  // Setup receive pin.
  vw_setup(2000); // Transmission speed in bits per second.
  vw_rx_start(); // Start the PLL receiver.
}
 
void loop()
{
  uint8_t buf[VW_MAX_MESSAGE_LEN];
  uint8_t buflen = VW_MAX_MESSAGE_LEN;
  if(vw_get_message(buf, &buflen)) // non-blocking I/O
  {
    int i;
    // Message with a good checksum received, dump HEX
    Serial.print("Got: ");
    for(i = 0; i < buflen; ++i)
    {
      Serial.print(buf[i], HEX);
      Serial.print(" ");
	  //Serial.print(buf[i]);
    }
    Serial.println("");
  }
