Stalker V3 & RX/TX Xbee

I’m newbie; in order to Xbee Stalker V3 works, I must use 2 wires (XBEE/TX to DO Stalker; XBEE/RX to D1 Stalker); by seeing schematics Eagle I see connexion exists already, but it’s don’t work, I don’t know why ?
Somebody could help me ?
Best regards for all.


Have you solved this problem?
Through Uart to control XBee on Stalker V3, you need a Serial communication code on Arduino instead of XCTU.
