2.9.2 Store/Transmit Event Data
The user can configure the MT 3050 to store event-generated data in its internal memory to be sent over
the air to a remote server. This feature can be enabled or disabled using the AT$MSGLOGEN command.
“Total Number of Unread Messages” is decremented if an unread message is read via the AT$MSGLOGRD
command.
Example: Assume there are 50 unread messages in the message queue, and the total number of messages
in the message queue is 100. This means that the first 50 messages have been read while the last 50
messages have not been read. If a user sends
AT$GPSLOGRD=0,1,51
then the total number of unread
messages drops down to 49 after successful transmission of that message. However, if a user sends
AT$GPSLOGRD=0,1,99
then the total number of unread messages still remains at 50—that message is
transmitted to the remote server.
A user can also read a message stored in the memory by inputting the appropriate starting index number.
2.9.3 Synchronize RTC Time With GPS Time
The Real Time Clock ("RTC") is synchronized with GPS time automatically every time the device is powered
up and first acquires valid GPS data. Additionally, the RTC time is synched with GPS time every time the
GPS time rolls over from 23:59:59 to 00:00:01.
2.9.4 Reporting Frequency
The minimum reporting frequency of the device is as follows:
l
Periodic reporting is limited to max of 1 per 6 seconds.
l
The general reporting interval is 1 message every 2 seconds.
