<Sleep Mode (Low Power)> SM Command is

used to adjust Sleep Mode settings. By default,

Sleep Mode is disabled and the module remains

continually active. SM Command allows the

module to run in a lower-power state and be

configured in one of eight settings.

Cyclic Sleep settings wake the module after the

amount of time designated by SM Command. If

the module detects a wake-up initializer during

the time it is awake, it will synchronize with the

transmitter and start receiving data after the

wake-up initializer runs its duration. Otherwise, it

returns to Sleep Mode and continue to cycle in

and out of inactivity until the Wake-up Initializer

is detected. If a Cyclic Sleep setting is chosen,

the ST, LH and HT parameters must also be set

as described in the “Sleep Mode” section of this

manual.

Pin Sleep – PC (Power-up Mode), PW (Pin

Wake-up)

Serial Port Sleep – ST (Time before Sleep)

Cyclic Sleep – ST (Time before Sleep), LH

(Wake-up Initializer Timer), HT (Time Before

Wake-up Initializer), PW (Pin Wake-up)

ST (Time before Sleep) Command

<Sleep Mode (Low Power)> ST Command sets

the period of time (in tenths of seconds) in which

the module remains inactive before entering into

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

transmitting 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.
