I am trying out the document named "Analog to Digital Conversion on the XBee 802.15.4" on Digi.com. I have 2 analog IN values that need to be transferred to the Rx end Xbee 802.15.4 wirelessly. But I not getting any serial output at all on the Rx side. I followed all the setup as per document I mentioned. I am trying to get the UART out not the PWM output. But I am not seeing anything on the Rx end Arduino that is connected to the Rx Xbee. Did anyone ever tried that? Is there anything special that I need to do on these? Any help would be appreciated.
Do you have a connection to your VRef pin? I struggled once with this until I tried that. Just connect your 3.3V supply to VRef.
Can you hook up the receiving XBee so that it goes straight into a terminal program? Perhaps the issue is in your code, and that would confirm that the XBee is receiving. Many XBee carrier boards can be connected to an FTDI cable going into a USB port.
What are your transmitting XBee's settings?
Yes I have connected the vref to 3.3v. And tried connecting the Rx xbee on an explorer so I could see the Hex output on the X-CTU terminal. But there is my problem I do not see anything coming in on the X-CTU terminal. I have the configuration as per the Digi document. And I also have the same 2 analog INs like the document. But I do not see anything coming to my Rx xbee on the X-CTU terminal. My xbees are good, I double checked. I am not sure what is wrong. Thanks
Have you tried sending and receiving simple data through this pair of XBees? I assume that's what you mean when you say you double-checked them, but I'm just double-checking. 
Do your boards have blinking TX and RX lights on them? Can you tell from that whether the TX board is transmitting? Obviously if not, then that's where your problem is. If it is transmitting, well, you know the drill.
I am just using breakout board. I don't have any LEDs connected to them. But I made sure that my soldering was correct. Did your one worked? Did you do ADC conversion to UART out or PWM? Could you please send me your code on the receiving side arduino. May be I am doing something wrong.... Thanks
Sorry - I haven't received the data to an Arduino, just to a terminal program. That much worked just fine, but it doesn't help you any.
