SM (Sleep Mode) Command
<Sleep Mode (Low Power)> The SM Command is
used to set/read the RF module's Sleep Mode set-
tings that configure the module to run in states
that require minimal power consumption.
For more information regarding Sleep Modes,
refer to the Sleep Mode sections [p14]
ST (Time before Sleep) Command
<Sleep Mode (Low Power)> The ST Command is
used to set/read the period of time (in millisec-
onds) in which the RF module remains inactive
before entering Sleep Mode.
For example, if the ST Parameter is set to 0x64
(100 decimal), the module will enter into Sleep
mode after 10 seconds of inactivity (no transmit-
ting or receiving).
This command can only be used if Cyclic Sleep or
Serial Port Sleep Mode settings have been
selected using SM (Sleep Mode) Command.
TP (Board Temperature) Command
<Diagnostics> TP Command is used to read the
current temperature of the board.
