User Manual

The default value for DCS = 0 represents the default SMS sent by a mobile. If you do not
need any particular data coding scheme use DCS=0.
Not all the DCS combinations described in the 3gpp 3.38/23.038 are supported, both by the
network and by the Telit HE910V2. Some features may be not implemented at network level
or at device level, resulting in a +CME ERROR: 3 (operation not allowed) result code. If this
happens then use a different DCS.
 send command AT+CSMP=<fo>,<vp>,<pid>,<dcs><cr>
where:
<fo>: Message format
<vp>: Validity Period
<pid>: Protocol Identifier
<dcs>: Data coding Scheme
 wait for OK
For example:
1- Let us assume you want to set the SMS parameters to the values:
Message Format:
 SMS submit
 do not reject duplicates
 VP Format integer (relative)
 status report not requested
 No Header on PDU
 Reply path not set
Hence, the message format is the binary number 00010001 corresponding to the integer 17.
 Validity period 24 hours corresponding to an integer value 167. 12 hours + ((167
-143) x 30 min) = 24 hours
 Protocol ID implicit (SMS sent to a mobile terminal) corresponding to a value 0.
 DCS default value 0.
