I have just started using xbee rf modules a week ago and I have some trouble to set up a pushbutton and led scenario. I configured the two modules (with a xbee explorer) according to many tutorials I found using xctu (Version: 6.3.
but the led did not turn on when I pressed the button. so my question is ... how can I verify that the D0 pin that I configured as Digital Input receives a HIGH signal.
Is there any recent tutorial on this topic?
