Fast SYSHALT the GL865 V3/V3.1
The procedure to power OFF of module described in Chapter 5.2, normally takes up to 10
second to de-attach the network and internal filesystem properly closed.
The Fast SYSHALT feature permits to reduce the current consumption and the time-to-
power SYSHALT to minimum values.
NOTE:
Refer to AT command reference guide (Fast Sys Halt - #FASTSYSHALT) in
order to set up detailed AT command.
5.3.1.
Fast SYSHALT by Hardware
The module provides an input to give to the FW of the module advance notice that the power
source is failing and allow it to prepare for the power failure.
The Fast SYSHALT can be triggered by configuration of any GPIO. HIGH level to LOW
level transition of GPIO forces the fast power down procedure.
NOTE:
Consider voltage drop under max current conditions when defining the
voltage detector threshold in order to avoid unwanted shutdown.
