Sleep commands
The following commands are sleep commands.
SM (Sleep Mode)
Sets or displays the sleep mode of the device.
Normal mode is always awake. Pin sleep modes allow you to wake the device with the SLEEP_
REQUEST line. Asynchronous cyclic mode sleeps for SP time and briefly wakes, checking for activity.
Sleep Support mode is always awake but can effectively communicate with SM8 nodes. Synchronized
Cyclic Sleep nodes sleep for SP and wake for ST time.
Synchronous modes are unavailable if BR = 0 and are incompatible with asynchronous modes.
