Description

To set the mode how the module indicates new SMS messages received from the network to users

Format



AT+CNMI=<mode>[,<mt>[,<bm>[,<ds>[,<bfr>]]]]<CR>



AT+CNMI?<CR>



AT+CNMI=?<CR>

Parameter

<mode>: Set the indication mode after receiving SMS messages. 0: Buffer unsolicited result codes in the TA. If TA result code buffer is full, indications can

be buffered in some other place or the oldest indications may be discarded and replaced with the new received indications.

1: Discard indication and reject new received message unsolicited result codes when TA-TE link is reserved (e.g. in on-line data mode). Otherwise forward them directly to the TE.

2: Buffer unsolicited result codes in the TA when TA-TE link is reserved (e.g. in on-line data mode) and flush them to the TE after reservation. Otherwise forward them directly to the TE.

3 Forward unsolicited result codes directly to the TE. TA-TE link specific inband technique used to embed result codes and data when TA is in on-line data mode.

<mt>: Set the format of the new SMS indication codes. The default value is 0. 0: SMS indication codes will not be sent to the TE. 1: The format of the new SMS indication codes is +CMTI: "MT" ,<index>. The SMS

message is stored rather than directly displayed. 2: The format of the new SMS indication codes is

+CMT :<oa>,<scts>,<tooa>,<lang>,<encod>,<priority>[,<cbn>],<length><CR><LF> <data> (text mode). SMS messages are directly displayed rather than stored.

3: Use the report codes defined by <mt>=2 to transmit SMS indication codes to the TE. The SMS indication codes in other modes are the same as that of <mt>=1.

<bm>: Set the format of the new cell broadcast codes. The default value is 1. 0: Not send the indication information of new cell broadcast. The cell broadcast will not be

stored. 1: The cell broadcast indication code is +CBMI:" BC" ,<index> and the cell broadcast is

stored. 2: The format of the new cell broadcast indication codes is

<oa>,[<alpha>,]<scts>[,<tooa>,<length>] <CR><LF><data>(text mode). The cell broadcast will be directly displayed rather than stored.

3: The CBM of the third-type information will be displayed on the end device using the report codes defined by <bm>=2. For other type SMS messages that support CBM storage, the indication codes are the same as that of <bm>=1.

<ds>: Report status of SMS message sending. The default value is 1.

5.5 Setting the New Message SMS Indications Mode: +CNMI

Neo_WM620 WCDMA Module AT Command Set

36

0: No status report of SMS message sending 1: The format of the SMS sending status report is

+CDS :<fo>,<mr>,[<ra>],[<tora>],<scts>, <dt>,<st>(text mode).

<bfr>: The default value is 0. 0: When <mode> is set to 1 or 2, codes defined by this command and stored in TA will be

sent to TE. The module will return OK before transmitting the codes. 1: When <mode> is set to 1 or 2, the codes defined by this command and stored in TA will

be cleared.

Return Value

See the Example.

Example

AT+CNMI=2,1,0,0,0 OK

Set the SMS message indication mode.

AT+CNMI=? +CNMI:

Remarks

SMS messages are classified into four classes based on the storing:



Class0: displayed only



Class 1: Stored in the ME memory



Class 2: Stored in the SIM card

<cid>: (PDP Context Identifier) a numeric parameter that specifies a particular PDP context definition. The parameter is local to the TE-MT interface and is used in other PDP context-related commands. The range of permitted values (minimum value = 1) is returned by the test form of the command.

<PDP_type>: (Packet Data Protocol type) a string parameter. IP Internet Protocol (IETF STD 5)

<APN>: (Access Point Name) a string parameter which is a logical name that is used to select the GGSN or the external packet data network. If the value is null or omitted, then the subscription value will be requested.

<PDP_address>: a string parameter that identifies the MT in the address space applicable to the PDP. If the value is null or omitted, then a value maybe provided by the TE during the PDP startup procedure or, failing that, a dynamic address will be requested. The read form of the command will continue to return the null string even if an address has been allocated during the PDP startup procedure.

A Reference Process of AT Command Programming

A.1 Content of PDU SMS Messages

<PDU> SMS message sending format: 1>: 0891 08: indicates the length of the SMSC address information 91: indicates the format of the SMSC address 2>: Inversion of every two bits (add F if the bits are not sufficient) in SMSC number, fixed. For example,

China Unicom 8613010888500 should be 683108705505F0 here. 3>: 0100 01: Indicates basic parameters 00: indicates message baseline value 4>: Convert the receive ng number into hexadecimal. For example, the number length is 11 bits and then the hexadecimal length should

be 0B. 5>: 81 (Receiving mode) there are multiple receiving modes. 81 indicates that the receiving mode is

unknown. 6>: Inversion of every two bits (add F if the bits are not sufficient) in the recipient number. For example,

13421839693 should be 3124819396F3 after conversion. 7>: 0008 8>: The hexadecimal length of the SMS message content. For example, the UCS2 code of hello is

00080A00680065006C006C006F, that is 10 bits and the hexadecimal length is 0A. 9>: Message content, for example, the USC2 code of hello is 00080A00680065006C006C006F. One PDU message contains the above 9 parts and the parameter values are determined by the actual situation.

If the SMSC address length is 0, replace 08 with 00 and the SMSC type and address fields must be omitted.

The following is an example of the PDU message whose SMSC address length is not 0: 0891683110808805F001000B813124819396F300080A00680065006C006C006F Wherein, 0891 683108705505F0: SMSC number of China Unicom 0100 0B: the length of the recipient number 81: Receiving mode 3124819396F3: The number of recipient 0008 0A: The length of the content
