PM (Power Mode)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Set or read the power mode of the device. Enabling boost mode improves the receive sensitivity by
2dB and increase the transmit power by 3dB.

CA (CCA Threshold)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Set or read 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.
Note If device is operating in Europe, this value must be set to 0x34 to comply with EN 300 328 Listen
Before Talk requirements. Alternatively the device can be set to PL3 as explained in Europe (CE).
Parameter range
0x28 - 0x50
Default
0x2C (-44 decimal dBm)
