SM (Sleep Mode) Command
<Sleep Mode (Low Power)> The SM Command is
used to set/read the RF modem's Sleep Mode set-
tings that configure the modem to run in states
that require minimal power consumption.
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 modem remains inactive
before entering Sleep Mode.
For example, if the ST Parameter is set to 0x64
(100 decimal), the modem 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.
