New Message Acknowledgement: +CNMA
Description: This command allows reception of a new message routed directly to the TE to be
acknowledged.
• In TEXT mode, only positive acknowledgement to the network (RP-ACK) is possible.
• In PDU mode, either positive (RP-ACK) or negative (RP-ERROR) acknowledgement
to the network is possible.
Acknowledge with +CNMA is possible only if the +CSMS parameter is set to 1
(+CSMS=1) when a +CMT or +CDS indication is shown (see +CNMI command). If no
acknowledgement is given within the network timeout, an RP-ERROR is sent to the network, the
<mt> and <ds> parameters of the +CNMI command are then reset to zero (do not show new
message indication).
Command syntax in text mode: AT+CNMA
Command syntax in PDU mode: AT+CNMA [ = <n> [ , <length> [ <CR>
PDU is entered <ctrl-Z / ESC> ] ] ]
Note: PDU is entered using <ackpdu> format instead of <pdu> format (e.g.. SMSC
address field is not present).
