6.2.2 Receiving SMS
SMS are stored at the SMS storage locations in the SIM card. You can read out the num-
ber of all available SMS storage locations on the SIM card using the tab "Basic settings" in
the HSComm software in the group "GSM connection" and the button "Locate SIM SMS
storage locations now".
The INSYS GSM queries the SMS storage locations as soon as the INSYS GSM is not busy
with data connections, alarm processing or processing of
AT commands for 60 seconds.
Any activity at the serial interface (
AT
commands) restarts the query interval without
executing the query. No query is made during an active data connection.
Commands entered at the serial interface are ignored.
The baud rate and the number of SMS storage locations to be configured determine the
duration of the query.
Example:
Baud rate 19200 bps
Configured SMS storage loca-
tions: 15
Result:
Query duration: 5 seconds
