random Voltage

Hello all,

I seem to have an random voltage output at my receiving Xbee development board.
Seems to vary from .9 volts or so to 3.3 volts or somewhere near there.

The transmission side has been set up as Analog input no more then 3 volts.
I jumped the refV and the VCC.

The receiving end is setup at PWM.

The device output has a steady volts output of about.65 volts.
But the receiving end shows .55-.7 and moving around in that span.

Also channel one shows the same voltage of the .65 volts input on the transmitter, even do there is nothing connected to it.

Thanks for the help.

Which XBee module is this? What is the full part number for it?

What firmware version and function set are you working with?
