Sleep Commands
Name and Description
Wake Time.
Units of msec, represented in hex.
Note 1: the minimum value for ST is a function of SP, SS, MT, NN, and NH. If the user
attempts to set the value of ST too low it will automatically be increased to a minimum
effective value.
Note 2: To effectively enter command mode it is necessary that the value of ST is set
greater than the value of GT.
Sleep Period.
Units of 10 msec, represented in hex
Number of Missed Syncs.
Read the number of wake cycles that have elapsed since the last sync message was
received.
Missed Sync Count.
Count of the number of syncs that have been missed. This value can be reset by setting
ATSQ to 0. When the value reaches 0xFFFF it will not be incremented anymore.
Sleep Status
The SS command can be used to query a number of Boolean values describing the
status of the module.
Bit 0: This bit will be true when the network is in its wake state.
Bit 1: This bit will be true if the node is currently acting as a network sleep coordinator.
Bit 2: This bit will be true if the node has ever received a valid sync message since the
time it was powered on.
Bit 3: This bit will be true if the node has received a sync message in the current wake
cycle.
Bit 4: This bit will be true if the user has altered the sleep settings on the module so that
the node will nominate itself and send a sync message with the new settings at the
beginning of the next wake cycle.
Bit 5: This bit will be true if the user has requested that the node nominate itself as the
sleep coordinator (using the commissioning button or the CB2 command).
All other bits: Reserved - All non-documented bits can be any value and should be
ignored.
bit 6 = This bit will be true if the node is currently in deployment mode.
All other bits: Reserved - All non-documented bits can be any value and should be
ignored.
Operational Sleep Period.
Read the sleep period that the node is currently using. This number will oftentimes be
different from the SP parameter if the node has synchronized with a sleeping router
network.
Units of 10mSec
Operational Wake Period.
Read the wake time that the node is currently using. This number will oftentimes be
different from the ST parameter if the node has synchronized with a sleeping router
network.
Units of 1 mSec
Wake Host.
Set/Read the wake host timer value. If the wake host timer is set to a non-zero value,
this timer specifies a time (in millisecond units) that the device should allow after waking
from sleep before sending data out the UART or transmitting an IO sample. If serial
characters are received, the WH timer is stopped immediately. The device will shorten
its sleep period by the value specified with the WH command to ensure that it is
prepared to communicate when the network wakes up.
