Unsolicited Message Syntax
The modem can notify the application of events as they occur. There are two types of unsolicited messages:
those that the modem will always report and those that are optional.
The format for unsolicited messages is:
As a general rule, unsolicited messages are not embedded in an AT command response. The unsolicited
message may be returned after an AT command is issued and before the AT command response, but not in the
middle.
Therefore, the following is NOT possible:
However, the following example is possible:
It is strongly recommended to design the host application parser to ignore unrecognized unsolicited messages.
Such a design allows for modifications to the returned unsolicited messages for testing purposes and possible
future enhancements to the modem. Unsolicited messages are discarded while the modem is in 32khz sleep.
Unsolicited messages can be buffered under certain conditions. The buffer is 15 entries deep and when full will
drop the oldest messages for a new message. To control the unsolicited message continue, use AT+WUSLMSK.
AT commands are buffered in PPP and TCP online data. It is recommended that during buffering that the level of
unsolicited messages be dropped back as far as possible; the Ring Indicator can be used as a replacement for
many unsolicited messages.
