Notes
•
Configurations are not saved in non-volatile memory and lost when the module
boots. Configuration is needed each time the module boots up.
•
The module uses PDP context 1 (CID 1) to send the message. No check is done
between the address type and the PDP context type; only valid address syntax is
checked.
•
Messages are concatenated with the current time in ISO 8601 format when sent:
"<date>T<time><timezone> / YYYY-MM-DDThh:mm:ss±hh:mm".
Example: "TEST MESSAGE" is concatenated as "TEST MESSAGE 1997-07-
16T19:20:30+01:00"
•
The total length of the UDP sent is less than or equal to 160 characters. It is
recommended to configure the current time using the
+CCLK
command.
•
The last gasp UDP feature is only effective when CID 1 is activated.
•
The device shuts down immediately if there is no UDP configuration.
•
The device shuts down with a 2-second timeout in case of UDP sending failure due
to PDP bring-up failure or socket failure.
