XBEEs didn't work...

I tried to do the XBEE demo learn.parallax.com/tutorials/projects/xbee-802154-pc-demo on my Activity Board instead of Education Board but it didn't work! For the time being, I tried to test my thermometer (DS1620) with the Test_DS1620.spin and it worked first and the terminal displayed the "temperature = 76F" in every 5 seconds. However after 1 minute, the display for the temperature on terminal had disappeared. As I observed that the DI LED on XBEE was blinking red at first when it worked for 1 minute, and dimmed for the rest of the time. I doubt it has some thing to do with the baud rate and sampling rate which I am not sure!

I used XBEE USB dongle instead of XSTICK and I have set up XBEEs on XCTU for one Coordinator API mode and one End Device AT mode. I also set up the End Device's sampling rate for 5 seconds and D3 for ADC. I am not sure what's wrong and the fact that first time worked and then stopped really confused me..

I ran the test code again on PropIDE's terminal and it kind of worked: it displayed strange characters like the ones in picture. Does anyone know what did I do wrong?

I tested SimpleIDE's terminal and it is working. I don't know why PropIDE terminal does not work, it is strange..

I am more confused: I studied the test_DS1620.spin and it says debug port is 0 which I suppose is the USB serial terminal. I have run with USB terminal and it is working fine displaying temperature.
BUT why is it RANDOMLY working on the XBEE terminal as well? the code did not specify anything about XBEE I suppose? I hope some can help me on this.
