"PROFILE" Profile files This tag refers to the profile files that can be loaded on to the module to
support Mobile Network Operators (MNOs) specific configurations. For more
details on the profiles, see the +UMNOPROF command. The +URDFILE and
+ULSTFILE AT commands are not allowed with this tag, the user can only
download or delete these files.
"GNSS" GNSS files This tag has to be used to store the firmware file for the internal GNSS receiver.
"CALLSRV_EXT" Emergency Call
Number List (ECNL)
management
This tag is used to manage the Emergency Call Number List (ECNL) file stored
in NVM. All numbers in the list will be treated as emergency numbers when
dialled and will result in disabling the thermal daemon software shut-down.
Some notes about ECNL:
• If eCall is enabled, the ECNL list is not used and call is treated as any normal
call.
• Conflict manager will not manage these calls, meaning no ongoing calls will
be dropped.
• Maximum allowed numbers in the ECNL list is 20. Numbers after 20 will be
ignored.
• Reboot is required to reload the ECNL list after download.
File should be composed by text lines consisting of 'type','number' lines that end
with carriage return where 'type' is a type of the number in 'number' according
to one of the formats supported by 3GPP TS 24.008 [12] sub-clause 10.5.4.7).
All numbers that start with '00' should be stored with '+' instead in order to
keep only one occurrence for international number. In order to manage numbers
properly the configuration file should contain the number with international
prefix and without it.
Example of a two line ECNL file:
2,+390123456789
2,390123456789
"XLWM2M" LwM2M object script
files
This tag is used to read or store Lua files defining a LwM2M object for
use by the LwM2M client. The file specified with the "XLWM2M" can be
only downloaded completely (see +UDWNFILE AT command), deleted
(see +UDELFILE AT command), fully or partially read (see +URDFILE or
+URDBLOCK) and queried (see +ULSTFILE AT command). If the +UDWNBLOCK
AT command is issued to partially download file with the "XLWM2M" type tag,
the module returns an error result code.
