4.16.25. $OFFDLY Power off delay
Command Function This command allows the user to configure
the minimum time that the PWR_CTRL
signal must be low before the module
recognizes the signal as a power off
command. This delay can be considered
as a software debounce time for the
PWR_CTRL signal.
If the PWR_CTRL signal is held low for
longer than the time specified by $OFFDLY,
then the modem performs a software-
controlled shutdown. The modem
gracefully deregisters from the network
before powering down so it may take a few
seconds before current consumption
decreases. Requires a pulse on the
PWR_CTRL or RESET pin to wake the unit
back up.
