AT+CNMA New Message Acknowledgement to ME/TE
=1) execute command confirms reception of a new message (SMS-DELIVER or
SMS-STATUS-REPORT) which is routed directly to the TE. In PDU mode (
=0) write command is used
to send either positive (RP-ACK) or negative (RP-ERROR) acknowledgement to the network. Parameter
defines which one will be sent.
EHS6 will not send another "
" or "
" URC to the TE until previous one is acknowledged with this com-
mand. If the ME does not receive acknowledgement within required time (network timeout), it sends an "RP-
ERROR" message to the network. The ME will automatically disable routing to the TE by setting both
and
values of
to zero.
