Sudden Momentary Power Loss (SMPL) $WSMPL
Description: This command enables or disables the Sudden Momentary Power Loss feature.
When AT+CFUN is issued SMPL is disabled to allow for a normal power down and is enabled
again on power up.
Please note that if the command receives the input value that is the currently set parameter value
it will return an error. If Sudden Momentary Power Loss is already enabled and an application
tries to enable it again the command will return an error and the same is true for disable.
The setting is persistent. As a result, it is saved after a power cycle. The default is 0 (Disabled).
An SMPL event can cause a ring indication to a host application during sleep.
