So I'm completely new to this and I thought I was going about it the correct way by buying the Wireless Sensor Networks book when I purchased my boards and xbee's. I'm following along in the book and of course the book recommends that I do not use the pro xcs 900's but that is what I have and now I need some help.
I have the Xbee's configured to the default settings. I do not see anywhere in the settings using X_CTU where I can set the destination address high and destination address low. I only see a Destination address which it only accepts a 4 bit address. So I'm not sure what to do here. I originally left it alone because I think I read somewhere that if they were both on the same address that they would talk to each other.
Everything seemed to be going well until I loaded the doorbell sketch onto the Mega's. As soon as I load the sketch on I completely loose the ability to communicate with both Xbee's through X-CTU. This leads me to believe that is has something to do with the baud rate because it is setting it in the sketch using Serial.begin(9600). I can load the slow blink program I found in the tutorials and I can still talk to the Xbee's through X-CTU with no problems. I realize that the 9600 baud rate associated with the Xbee Pro is talking about the rate between Xbee's. So I thought maybe I should change the Serial.begin command to 19200 which didn't help either.
I feel like there is something that I'm missing so I decided to ask for help. So please if anyone knows what I'm doing incorrectly I would really appreciate it if you could guide me in the right direction.
