use pin 0 (RX) and 1 (TX) for wireless connection

Ok, this is the code i tried to use:

int send = 5;
int income = 0;

void setup() {
Serial.begin(9600);
}

void loop(){

// transmitter
Serial.print("I sent: ");
Serial.println(send, DEC);

// reciever
if (Serial.available()) {
// read the incoming byte:
income = Serial.read();

// say what you got:
Serial.print("I received: ");
Serial.println(income, DEC);
}
}

But I get an errror when i want to move the code to the arduino board. --> "Programmer is not responding." (even through pressing RESET)
When I remove the PINS from 1 (TX) and 0 (RX) installation is possible

THis is how I configured the board and the modules:

Thanks for your help
