I am trying to make a connection between 2 Arduino's with the APC220 rf modules.

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

void loop() {
   int value = 5;
   Serial.println(value);
   delay(1000);
}

I uploaded this code to my Arduino Nano and Uno. I disconnected the rf modules for uploading the code.

I tried to run this program with an external power source (lipo 11.1V 2200mAh). The Arduino is powered on(power led is on) BUT the tx led doesn't blink.

The only way to make it work is by using the usb and opening the serial monitor on my pc.

I tried to use a 10k resistor between tx and rx (or rx to ground) but the code won't run...

Can someone help me?

Solution : the arduino worked perfect. When you connect the arduino with an exernal power supply the tx and rx lights won't light up, Even when they are transmitting or receiving.
