When i use XBee Java Library User Guide.
I use the code to test my Xbee.
the code is here(the same with the code in pdf) and i find something strange。
package com.digi.xbee.example;
import com.digi.xbee.api.WiFiDevice;
import com.digi.xbee.api.XBeeDevice;
import com.digi.xbee.api.exceptions.XBeeException;
import com.digi.xbee.api.models.XBeeProtocol;
public class MainApp {
/* Constants */
// TODO Replace with the port where your sender module is connected to.
private static final String PORT = “COM5”;
// 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);
byte[] dataToSend = DATA_TO_SEND.getBytes();
try {
myDevice.open();
byte[] sleepTime = myDevice.getParameter(“SP”);
System.out.println(sleepTime[0]);
System.out.format(“Sending broadcast data: ‘%s’”, new String
(dataToSend));
if (myDevice.getXBeeProtocol() == XBeeProtocol.XBEE_WIFI) {
myDevice.close();
myDevice = new WiFiDevice(PORT, BAUD_RATE);
myDevice.open();
((WiFiDevice)myDevice).sendBroadcastIPData(0x2616, dataToSend);
} else
myDevice.sendBroadcastData(dataToSend);
System.out.println(" >> Success");
} catch (XBeeException e) {
System.out.println(" >> Error");
e.printStackTrace();
System.exit(1);
} finally {
myDevice.close();
}
}
}
when i connect my xbee with a arduino uno R3,i got this :

i DO determine that my xbee is in API mode.And the interesting thing is that i also have a arduino board without chip(so it can not upload program in arduino).When i use this borken board,this code can run well,and i can receive “Hello XBee World” from XCTU.
Does anyone have a similar problem？Can anyone give me some advice?
