AT commands
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
The following table shows the TX power versus the PL setting.

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, and negative values are represented in two's complement; for example, -
5 dBm = 0xFB.
Parameter range
0 - 0xFF [read-only]
Default
N/A
CH (Operating Channel)
Set or read the operating channel devices used to transmit and receive data.
In order for devices to communicate with each other, they must share the same channel number. A
network can use different channels to prevent devices in one network from listening to the
transmissions of another.
The command uses 802.15.4 channel numbers.
