I'd like to transmit digital sensor readings (two inputs) from one XBEE platform board powered by 9V battery  to another XBEE platform board connected to a PC . The one sensor connects SO/CS/SCK > AD3/AD2/AD1 on the XBEE; the other connects IN_RX/IN_CTS/OUT/TX/OUT_RTS > Dout/CTS/Din/RTS.
Can I test remote sensing entirely with AT commands? Is there an example on the web?
If not, I assume that I'd have to set  to API mode; program  to wake-up regularly and transmit a frame from sensor 1 and 2, hopefully not at the same time. Is there a worked example of this on the web?
