4.2.11.17
Notification of no space to save SMS messages
This unsolicited response indicates that an incoming SMS message cannot be saved because there is no
room remaining in the memory on the CM52. Under this condition the CM52 returns a NACK to the network.
The network keeps the message and attempts to resend it again at another time. When this unsolicited
message is received, all SMS messages stored on the CM52 should be read or deleted. The current size of
the SMS buffer on the CM52 is 10 messages. The CM52 SMS message storage feature is intended to provide
only a small buffer to temporarily hold a few messages while the host application is performing other actions.
The format of the unsolicited response is:
*EUNSOL: BUFFERFULL
4.2.11.18 Timestamp
message
This unsolicited response is a timestamp heartbeat. The purpose of this unsolicited response is to provide a
timestamp that can be used in Diagnostic logs to locate events. This message should NOT be used for
anything else. SEMC recommends that customers code the ability to handle this message in their application.
By doing so, SEMC and the customer can match diagnostic logs to AT command logs.
If timestamp is enabled, the message will be reported every 10 seconds while the module is not in deep sleep
mode. When the module is sleeping the time span can vary. The timestamp always matches the timestamp in
the diagnostic log. Additionally, if on a digital system, the timestamp is in GMT + the time zone and the
module rescans to AMPS after digital service, the time will remain. If the module powers on and locates
AMPS service, the timestamp starts at 00:00:00 and keeps relative time from that point until digital service is
found, at which point the timestamp will reflect network time.
The format of the unsolicited response is:
*EUNSOL: TIME STAMP,HH:MM:SS
Where hh is 00-23, mm is 00-59, and ss is 00-59.
4.2.11.19 DTMF
message
In CDMA mode, this unsolicited response is an indication to the application that a voice call is active and the
external application sent over-dial digits through a burst DTMF message to the network. Refer to ATD over-
dial for more details.
