I configured the Xbee following this tutorial. When i tried to communicate with the Xbee node in the network using the command:

$ rosrun rosserial_xbee xbee_network.py /dev/ttyUSB0 1

I am getting the error as below

[ERROR] [WallTime: 1487541445.323876] Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

I tried altering baud rate, Delay etc in Arduino but it dint help, how to get around with this issue

Hardware used: Xbee series 1, Abee explorer, Arduino UNO.
