I'm about to ask a related question - but can answer yours... this applies to an S2B

in AT mode, use +++ to get to the AT command prompt, and enter ATDB

in API mode, use a packet like: 7e 00 04 08 52 44 42 1F

You'll get a response like: 7e 00 06 88 52 44 42 00 2F 70

the last 2 bytes before the checksum are the signal strength (00 2F)

enter into AT mode by giving +++

once entered it replies with OK

type ATDB and enter

you will get the nearby paired xbee RSSI value(if series2) for series 1 it automaticallt detects and eply with rssi value....

from the RSSI dbm value the distance can be calculated easily.

as checked for

rssi 0
<1 mtrs

rssi 1
>1 to <3 mtrs

rssi 2
>3 to <5 mtrs

rssi 3
>5 to <7 mtrs

rssi 4
>7 to <9 mtrs

rssi 5
>9 mtrs
