I am just starting out a project and I am having a little bit of trouble. I want to send data collected from an IR distance sensor, and send it with an XBee Pro S2B to my computer so I can do other stuff with it. The code I am using right now is pretty simple:
void setup()
{
Serial.begin(9600);
}
void loop(){
int distance = analogRead(0);
Serial.println(distance);
delay(1000);
}
The problem I am having is that when I turn on the arduino with batteries and disconnect the usb cable, the tx light stops turning on and no serial data is sended, AND if I connect it to the computer via USB again it won't work anyway, only works right when I upload the code. The XBees are configured correctly, I have done the chat example on the Building Wireless Sensor Networks by Robert Faludy.
Is it some code error? I must be really obvious. By the way, when I upload the code and the serial data is sended throught usb, the data displayed on Arduino IDE's console is correct, so the sensor is wired correctly.
I am using an Arduino UNO and I have the XBee's and arduino's drivers installed correctly, and for the XBee I am using the XBee Explorer from Sparkfun
