MC52i AT Command Set

MC52i AT Command Set
15.1 Usage of Remote-SAT
If both an alpha identifier or text string, and an icon are provided with a proactive command, and both are
requested to be displayed, but the ME is not able to display both together on the screen, then the alpha identifier
or text string takes precedence over the icon.
If the SIM provides an icon identifier with a proactive command, then the ME shall inform the SIM if the icon could
not be displayed by sending the response "Command performed successfully, but requested icon could not be
displayed" (via AT^SSTR).
The icon data can be fetched directly from the SIM via command AT+CRSM, for details please refer to GSM
11.11, Annex G. The icon data can be read from the SIM on system start then cached.
15.1.6 Using SMS Related AT Commands
ME activities triggered by SAT often end in sending or receiving short messages. Usually, a short message containing
a service request is sent to the network, for example a request to send the latest news. Subsequently,
the network returns a short message containing the requested information. This short message needs to be read
by the application running on the TE.
Set SMS text mode
AT+CMGF=1
Activate the display of a URC on every received SMS
AT+CNMI=1,1
If needed activate extended SMS text mode parameter output
AT+CSDH=1
This is useful in order to obtain more detailed header information along with the incoming SMS (e.g. SMS class).
Please refer to 3GPP standard GSM 03.38 for details.
As a result, a URC will be output each time a short message is received
+CMTI: "MT", 1 where
• the first parameter "MT" specifies the storage type of the SMS
• the second parameter contains a unique location number.
In the given example, the short message was stored to the memory type "MT" at location number 1.
The short message storage "MT" is a logical storage. It is the sum of the two physical storages "ME" (Mobile
Equipment message storage) and "SM" (SIM message storage). For more detailed information please refer to
[1], particularly AT+CPMS and AT^SSMSS.
To read the SMS data use
AT+CMGR=
where is the location number of the received SMS, e.g. 1 in the example above.
To list all stored short messages use
AT+CMGL="ALL"
To delete a certain SMS after reading use
AT+CMGD=
