I have a couple of XBEE S2 with RPSMA antenna I'm using the xbee explorer(with arduino) and XBIB development board with X-CTU on a PC.
if I drive the arduino from the USB,,, it works... not really fine, but there's some data beeing sent and received.
However, as soon an i move to batteries (http://www.batteryspace.com/li-ion18500cylindricalrechargeablecell37v1400mah518wh---ullisted.aspx) NOTHING works! the xbee xplorer's tx blinks but i receive nothing on the other end. the arduino's XBEE doesn't even receive anything.
i have other components connected and they are ALL working fine except for the XBEE. I know that the program is still there and the power is OK. what can be wrong!
here's a simple schematic
