Sleep

Sleep Mode. <NonBeacon firmware> Set/Read Sleep Mode configurations.
0 - 5
0 = No Sleep
1 = Pin Hibernate
2 = Pin Doze
3 = Reserved
4 = Cyclic sleep remote
5 = Cyclic sleep remote
w/ pin wake-up
6 = [Sleep Coordinator] for
backwards compatibility
w/ v1.x6 only; otherwise,
use CE command.
0
ST
Sleep
(Low Power)
Time before Sleep. <NonBeacon firmware> Set/Read time period of inactivity (no
serial or RF data is sent or received) before activating Sleep Mode. ST parameter is
only valid with Cyclic Sleep settings (SM = 4 - 5).
Coordinator and End Device ST values must be equal.
Also note, the GT parameter value must always be less than the ST value. (If GT > ST,
the configuration will render the module unable to enter into command mode.) If the ST
parameter is modified, also modify the GT parameter accordingly.

SP
Sleep
(Low Power)
Cyclic Sleep Period. <NonBeacon firmware> Set/Read sleep period for cyclic sleeping
remotes. Coordinator and End Device SP values should always be equal. To send
Direct Messages, set SP = 0.
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).

DP (1.x80*)
Sleep
(Low Power)
Disassociated Cyclic Sleep Period. <NonBeacon firmware>
End Device - Set/Read time period of sleep for cyclic sleeping remotes that are
configured for Association but are not associated to a Coordinator. (i.e. If a device is
configured to associate, configured as a Cyclic Sleep remote, but does not find a
Coordinator, it will sleep for DP time before reattempting association.) Maximum sleep
period is 268 seconds (0x68B0). DP should be > 0 for NonBeacon systems.

Interface Data Rate. Set/Read the serial interface data rate for communications
between the RF module serial port and host.
Request non-standard baud rates with values above 0x80 using a terminal window.
Read the BD register to find actual baud rate achieved.
