NOTE: Not all the DCS combinations described in the GSM 3.38 are supported, both by the
network and by the Telit GM862-QUAD / PY. Some features may be not implemented at network
level or at device level, resulting in a +CMS ERROR: 303 (operation not supported) 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's assume you want to set the SMS parameters to the values:
- Message Format:
- SMS submit
- don't 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.
command:
AT+CSMP= 17,167,0,0
response:
OK
2- Let's assume you want to set the SMS parameters to the values:
- Message Format:
- SMS submit
- don't reject duplicates
- VP Format semi octet (absolute)
- status report requested
- No Header on PDU
- Reply path not set
Hence, the message format is the binary number 00111001 corresponding to the integer 57.
- Validity period format is absolute, hence it represents the expiration date of the message and the
desired expiration date is for example 29/06/02 at 02:20 in the time zone of Italy (+1).
