Parameter Range Default
PL
Power Level. Select/Read the power level at which the RF module transmits conducted
power.
CRE
XBee
(boost mode disabled)
0 = -8 dBm
1 = -4 dBm
2 = -2 dBm
3 = 0 dBm
4 = +2 dBm
XBee-PRO
4 = 17 dBm
XBee-PRO
(International Variant)
4 = 10dBm
4
PM
Power Mode. Set/read the power mode of the device. Enabling boost mode will improve
the receive sensitivity by 1dB and increase the transmit power by 2dB
Note: Enabling boost mode on the XBee-PRO will not affect the output power. Boost
mode imposes a slight increase in current draw. See section 1.2 for details.
CRE
0-1,
0= -Boost mode disabled,
1= Boost mode enabled.

DB
Received Signal Strength. This command reports the received signal strength of the
last received RF data packet. The DB command only indicates the signal strength of the
last hop. It does not provide an accurate quality measurement for a multi-hop link. DB
can be set to 0 to clear it. The DB command value is measured in -dBm. For example if
DB returns 0x50, then the RSSI of the last packet received was
-80dBm.
CRE

Observed range for
XBee-PRO:
