SHOWVER - Show Version
Non-Volatile Address = 0x0A
Setting the SHOWVER register to 0x00 suppresses the start-up message,
including firmware version, which is sent out of the UART when the module
is reset. A value of 0x01 causes the message to be output after reset. By
default, the module start-up message is output. Figure 57 shows examples
of the commands and Figure 58 shows the available values.

V Meaning
0x00 Startup message is NOT output on reset or power-up.
0x01
Startup message is output on reset or power-up. This is a
blocking operation, and any incoming UART data is lost during the
transmission of this message through the CMD_DATA_OUT line. All
UART commands must be sent after this message has completed.

ENCSMA - CSMA Enable
Volatile Address = 0x56; Non-Volatile Address = 0x0B
Carrier-Sense Multiple Access (CSMA) is a best-effort transmission protocol
that listens to the channel before transmitting a message. If another
device is already transmitting on the same channel when a message is
ready to send, the module waits before sending its payload or changes
to an unused channel. This helps to eliminate RF message corruption at
the expense of additional latency. By default, CSMA is enabled. Figure
59 shows examples of the commands and Figure 60 shows the available
values.
See the Carrier Sense Multiple Access section for details.
