I using XBee Pro SX rf module mounted on sx development board and using XBee java library to open the xbeedevice conenction and broadcast a message.
Below is the code i am running in Eclipse-
public class MainApp {
/* Constants */
// TODO Replace with the port where your sender module is connected to.
private static final String PORT = “/dev/tty.usbserial-FTKDZ7DC”;
// TODO Replace with the baud rate of your sender module.
private static final int BAUD_RATE = 9600;
private static final String DATA_TO_SEND = “Hello XBee World!”;
public static void main(String[] args) {
XBeeDevice myDevice = new XBeeDevice(PORT, BAUD_RATE);
System.out.println(“device info:”+myDevice.toString()+“~~~”+myDevice.isOpen());
byte[] dataToSend = DATA_TO_SEND.getBytes();
try {
myDevice.open();
System.out.format(“Sending broadcast data: ‘%s’”, new String
(dataToSend));
myDevice.sendBroadcastData(dataToSend);
System.out.println(" >> Success");
} catch (XBeeException e) {
System.out.println(" >> Error");
e.printStackTrace();
System.exit(1);
} finally {
myDevice.close();
}
}
}
I am getting the follwing error when i try to open the xbeedevice:
com.digi.xbee.api.exceptions.XBeeException: Error reading device information.
