RF interfacing commands
The following AT commands affect the RF interface of the device.
PL command
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
The following table shows the TX power versus the PL setting.
PL setting XBee3 TX power XBee3-PRO TX power
4 8 dBm 19 dBm
3 5 dBm 15 dBm
2 2 dBm 8 dBm
1 -1 dBm 3 dBm
0 -5 dBm -5 dBm
Default
4
PP command
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. The CCA threshold is set upon device initialization,
any change to the CCA threshold must be written to flash with the WR command and the module
reset (power cycle or FR command) before the new threshold is observed.
