Hello,
I am trying to establish a simple wireless communication between two arduino unos R3 by using JS XBEE shield and the XBee model series 1. I configured the two Xbees sucessfully and now am trying to have the arduinos send and receive a simple message with the JS Xbee shield. The code I have is as shown below and basically is to have the arduino print H and L on the serial monitor. I first tested if the XBees were sending and receiving okay and from the CTU terminal the XBEE receiver did not print H and L but printed Letters and symbols. How can I ensure that the arduino uno is communicating with the XBee model correctly? I am relatively new to these devices and from tutorials they said to move the jumper to XBEE setting but on the shield and the arduino uno I can't tell where the jumpers are. I feel like they are soldered on already and cannot be moved. A friend of mine said that once you connect the xbee to the shield the arduino should be connected and sending data to the shield. How can I be so sure though he is right? Anyway to check and make sure the xbee and arduino are talking to each other? Thank you!
Code was using:
void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.print('H');
delay(1000);
Serial.print('L');
delay(1000);
}
