Xbee PRO and Xbee PRO S1

Is there any difference in working characteristic between Xbee pro AND xBEE prOs1 ?

Hmm, your questions uncertain. Do you mean the Xbee running ZigBee (the S2) and the Xbee running only 802.15.4 (the S1?)?

If so, there are huge differences. The 2 XBee can be swapped in hardware, but they cannot talk to each other.
