I configured two XBees using XCTU, connected them to the computer and sent Bytes back and forth. Works.
This is the current, non-working setup:
• 1 XBee, connected to an Arduino Mega using SparkFun XBee Explorer USB
• 1 XBee, connected to an Arduino Mega using SparkFun XBee Explorer Regulated
-
GND to GND
-
5V to 5V on the Arduino
-
DOUT to RX1 on the Arduino
-
DIN to TX1 on the Arduino
void setup() {
Serial1.begin(9600);
pinMode(13, OUTPUT);
//After 3 seconds the XBee should send out a couple of "A"s coming from the serial port
delay(3000);
int i = 0;
while (i < 10) {
Serial1.print("A");
delay(100);
i++;
}
}
void loop() {
//If anything is sent to the XBee it should appear in the Arduino's serial buffer
//making the LED on pin 13 turn on
if (Serial1.available() > 0) {
digitalWrite(13, HIGH);
}
}
The DIN LED on the Explorer Regulated flashes as supposed to but nothing is received on the computer where my Terminal application is listening.
Same when I send something from the Terminal, the LED on pin 13 of the Arduino does not indicate any bytes in the buffer, meaning that the XBee probably never received anything.
