3.5.1.4 Select New Messages indication behavior

When the device receives a new message a unsolicited indication is generated, this indication may be

sent to the DTE, buffered if the DTE is busy (for example during a data call) or discarded.

To set the desired behavior:

•

send command

AT+CNMI=<mode>,<mt>,<bm>,<ds>,<bfr><cr>

where:

Set command selects the behaviour of the device on how the receiving of new messages from the

network is indicated to the DTE.

Parameter:

<mode> - unsolicited result codes buffering option

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, otherwise forward them directly to the TE.

2 - Buffer unsolicited result codes in the TA in case the DTE is busy and flush them to the TE after

reservation. Otherwise forward them directly to the TE.

3 - if <mt> is set to 1 an indication via 100 ms break is issued when a SMS is received while the

module is in GPRS online mode. It enables the hardware ring line for 1 s. too.
