Synchronize Rtc Time With Gps Time; Reporting Frequency - Novatel RTT2211 User Manual

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.
