The Telit wireless modules store the values set by several commands in the internal non-
volatile memory (NVM), allowing this setting to remain even after power off. In the NVM
these values are set either as
factory profile
or as
user profiles
: there are
two customizable
user profiles
and
one factory profile
in the NVM of the device. By default the device will
start with user profile 0 equal to factory profile.
For backward compatibility each profile is divided into two sections, one
base section
that
was historically the one that was saved and restored in early releases of code, and the
extended section
, which includes all the remaining values.
The
&W
command is used to save the actual values of
both sections
of profiles into the
NVM user profile.
Commands
&Y
and
&P
are both used to set the profile to be loaded at start up.
&Y
instructs
the device to load at start up only the
base section
.
&P
instructs the device to load at start up
the full profile:
base + extended sections
.
The
&F
command resets to factory profile values in the base section of profile, while the
&F1
resets to factory profile values in the full set of base + extended section commands.
The values set by other commands are stored in NVM outside the profile: some of them are
stored always, without issuing any
&W
, while others are stored by issuing specific
commands (
+CSAS
,
#SLEDSAV
,
#VAUXSAV
,
#SKTSAV
,
#ESAV
); all of these values
are read at power-up.
The values set by following commands are stored in the profile base section:
