Which XBees? Series 1 or 2?

Which is the Firmware Version as reported by ‘Test/Query’ in X-CTU? This will tell us exactly which XBee you have and which document covers that XBee. Have you downloaded and read the Digi XBee doc?

What are the parameter settings in both XBees?

How are you sending an ‘A’ into the XBee?

What software are you using on the PC to send/receive from the XBee?

Which Interface between the XBee and PC are you using?
