I am sending data from xbee pro s1 module to the same type of xbee receiver. The receiver's being mounted on the xbee usb explorer from the Sparkfun.
16-bit data has been separated into two packages for each of them is 8-bit size.
My problem is that the received data shown on the xctu terminal are only dots, however, when I checked the hex number of them, they are all correct.
More strangely, I found that the Xbees would not work(transmit data) when the data value is 0..e.g. The wireless transmission would stop at the point where the data is 0!
Can you please tell me how could that happen? It is so weird for me.
