Configuration via SMS if the INSYS GPRS 5.0 serial is protected by a 
password and a confirmation is required. 
 
 
 
Note: Between CN: <phonenumber> a space character must 
be inserted. If no phone number is entered after CN: no phone 
number 
the response will automatically be sent 
to the sender. 

To protect against unauthorized configuration or attempts to estab-
lish a connection, two protection mechanisms are available which 
are also used for incoming SMS. 
Configuration password 
Note: see also Chapt. 6.1.1 -Password Protection 
 
 
Selective call acceptance 
Note: see also Chapt. 6.1.2 - Delete password 

 
 
Depending on the settings, SMS from unauthorized senders or with 
an invalid password are either 

¾

  Deleted immediately, or 

¾

  Stored in the memory and not processed 

 

The automatic processing of an incoming SMS takes place via an in-
dependent, module-internal interface and has usually no effect on the 
communication between the application and the GSM/GPRS engine. 
 
Only when the SMS memory is accessed (especially reading and delet-
ing), it can happen that the µcontroller accesses the SMS storage 
location at the same time. In this case, the application would receive 
ERROR as response. The application should therefore execute the 
command once more, if necessary. 
The INSYS GPRS 5.0 serial evaluates all SMS storage locations made 
available by the GSM/GPRS engine (storage locations of the SIM card 
and storage locations in the engine itself).
