I purchase 2 xbee S2 modules. One I can communicate with both XCTU and a terminal. The other can only communicate via the terminal but XCTU cannot talk to the module. I am using an Arduino UNO to talk to the xbee thru a USB/COM Port conn. This problem appeared after I tried to tweak the firmware. I have seen solutions talked about. A reset switch (but there is no reset switch on the xbee of course). Also this on digi talks about resetting the xbee but I do not know what specific development board (with url for the product itself) can be used to execute a reset. Does anyone have any suggestions? Thanks ---

The answer would be XBIB-R-Dev Board. Check below link… [http://www.digi.com/support/productdetl.jsp?pid=3683&osvid=62&tp2=0&tp=3](http://www.digi.com/support/productdetl.jsp?pid=3683&osvid=62&tp2=0&tp=3) ---

I found out how to do a reset. Is there any explanation of how the terminal works for regular term comm but not for xctu which is using the same terminal parameters? ---

The XBee module UART output setting ends with \r only rather than . I hope this what you are asking about
