RF interfacing commands

The following AT commands affect the RF interface of the device.

PL (TX Power Level)

Sets or displays the power level at which the device transmits conducted power.
Note If operating on channel 26 (CH = 0x1A), output power will be capped and cannot exceed 8 dBm
regardless of the PL setting.
Parameter range
0 - 4
PL setting XBee3 TX power
4 8 dBm
3 5 dBm
2 2 dBm
1 -1 dBm
0 -5 dBm
Default
4

PP (Output Power in dBm)

Display the operating output power based on the current configuration (channel and PL setting). The
values returned are in dBm, with negative values represented in two's complement; for example:
-5 dBm = 0xFB.
Parameter range
0 - 0xFF [read-only]
Default
N/A

CA (CCA Threshold)

Defines the Clear Channel Assessment (CCA) threshold. Prior to transmitting a packet, the device
performs a CCA to detect energy on the channel. If the device detects energy above the CCA
threshold, it will not transmit the packet.
The CA parameter is measured in units of -dBm.
