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.
