+CNMA New Message Acknowledgement to ME/TE

Description: The write / execute command confirms successful receipt of a new message (SMS-

DELIVER or SMS-STATUS-REPORT) routed directly to the TE. If ME does not receive

acknowledgment within required time (network time-out), ME sends RP-ERROR to the

network. TA shall automatically disable routing to TE by setting both <mt> and <ds>

values of AT+CNMI to zero.

Syntax:

Test Command: AT+CNMA=?

Test Response: +CNMA: (list of supported <n>s)

Exec. Command: AT+CNMA

Exec. Response: OK

ERROR

+CMS ERROR <err>

Write Command: AT+CNMA=<n>

Write Response: OK

ERROR

+CMS ERROR: <err>

Parameter Description:

<n> Parameter required only for PDU mode.

0 Command operates similarly as in text mode.

1 Send positive (RP-ACK) acknowledgement to the network. Accepted only in PDU mode.

2 Send negative (RP-ERROR) acknowledgement to the network. Accepted only in PDU

mode.

Note:

The execute / write command shall only be used when AT+CSMS parameter <service> equals 1 (= phase

2+) and appropriate URC has been issued by the module; i.e.:

<+CMT> for <mt>=2 incoming message classes 0,1,3 and none;

<+CMT> for <mt>=3 incoming message classes 0 and 3;

<+CDS> for <ds>=1.
