SM (Sleep Mode) Command
<Sleep Mode (Low Power)> The
SM command is used to set and
read Sleep Mode settings. By
default, Sleep Modes are disabled
(SM = 0) and the RF module
remains in Idle/Receive Mode.
When in this state, the module is
constantly
ready to respond to either serial or
RF activity.
SM command options vary
according to the networking system
type. By default, the module is
configured to operate in a
NonBeacon system.
* The Sleep Coordinator option
(SM=6) only exists for backwards
compatibility with firmware version
1.x06 only. In all other cases, use
the CE command to enable a
Coordinator.
SP (Cyclic Sleep Period) Command
<Sleep Mode (Low Power)> The SP
command is used to set and read
the duration of time in which a
remote RF module sleeps. After the
cyclic sleep period is over, the
module wakes and checks for
data. If data is not present, the
module goes back to sleep. The
maximum sleep period is 268
seconds (SP = 0x68B0).
The SP parameter is only valid if the
module is configured to operate in Cyclic Sleep (SM = 4-6). Coordinator and End
Device SP values should always be equal.
To send Direct Messages, set SP = 0.
NonBeacon Firmware
End Device - SP determines the sleep period for cyclic sleeping remotes. Maximum
sleep period is 268 seconds (0x68B0).
Coordinator - If non-zero, SP determines the time to hold an indirect message before
discarding it. A Coordinator will discard indirect messages after a period of (2.5 * SP).
