ST (Time before Sleep)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Sets or displays the wake time of the device.
The ST parameter is only valid for end devices configured with Cyclic Sleep settings (SM = 4 - 5) and
for coordinators.
Coordinator and End Device ST values must be equal.
Parameter range
1 - 0xFFFF (x 1 ms)

SP (Cyclic Sleep Period)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Sets and reads the duration of time that a remote device sleeps. After the cyclic sleep period is over,
the device wakes and checks for data. If data is not present, the device goes back to sleep.
The SP parameter is only valid if you configure the end device to operate in Cyclic Sleep (SM = 4-5).
Coordinator and End Device SP values should always be equal.
