+CNMI – new message indications to terminal equipment
Class 2 messages and messages in the message waiting indication group
(stored message) result in indication as defined in <mt> = 1.
3 - Class 3 SMS-DELIVERs are reported directly to TE using unsolicited
result codes defined in <mt> = 2. Messages of other data coding schemes result in
indication as defined in <mt> = 1.
<bm> - broadcast reporting option
0 - Cell Broadcast Messages are not sent to the DTE
2 - New Cell Broadcast Messages are sent to the DTE with the unsolicited result
code:
+CBM: <length><CR><LF><PDU> ( in PDU mode)
or
+CBM:<sn>,<mid>,<dcs>,<pag>,<pags><CR><LF><text> (in text mode)
where:
<length> - PDU length
<PDU> - message PDU
<sn> - message serial number
<mid> - message ID
<dcs> - Data Coding Scheme
<pag> - page number
<pags> - total number of pages of the message
<text> - message text
<ds> - SMS-STATUS-REPORTs reporting option
0 - status report receiving is not reported to the DTE
1 - the status report is sent to the DTE with the unsolicited result code:
+CDS: <length><CR><LF><PDU> (PDU mode)
or
+CDS: <fo>,<mr>,,,<scts>,<dt>,<st> (text mode)
2 - if a status report is stored, then unsolicited result code is sent:
+CDSI: <memr>,<index>
where
<memr> - memory storage where the new message is stored ("SM")
<index> - location on the memory where SMS is stored
<length> - PDU length
<PDU> - message PDU
<fo> - first octet of the message PDU
<mr> - message reference number
<scts> - arrival time of the message to the SC
<dt> - sending time of the message
<st> - message status as coded in the PDU
<bfr> - buffered result codes handling method
0 - TA buffer of unsolicited result codes defined within this command is
flushed to the TE when <mode> 1…3 is entered (OK response shall be given
before flushing the codes)
1 - TA buffer of unsolicited result codes defined within this command is
cleared when <mode> 1…3 is entered.
Note: DTR signal is ignored, hence the indication is sent even if the DTE is
inactive ( DTR signal is Low). In this case the unsolicited result code may be lost
so if TRIZIUM remains active while DTE is not, at DTE startup is suggested to
check whether new messages have reached the device meanwhile with command
AT+CMGL=0 that lists the new messages received.
