CA (CCA Threshold) Command

<RF Interfacing> CA command is used to

set and read CCA (Clear Channel

Assessment) thresholds.

Prior to transmitting a packet, a CCA is

performed to detect energy on the transmit

channel. If the detected energy is above

the CCA Threshold, the RF module will not

transmit the packet.

CC (Command Sequence Character)

Command

<AT Command Mode Options> The

CC command is used to set and read

the ASCII character used between

guard times of the AT Command Mode

Sequence (GT + CC + GT). This sequence enters the RF module into AT Command

Mode so that data entering the module from the host is recognized as commands

instead of payload.

The AT Command Sequence is explained further in the AT Command Mode section.

CE (Coordinator Enable) Command

<Serial Interfacing> The CE command is

used to set and read the behavior (End

Device vs. Coordinator) of the RF module.
