Message Log Queue Size
restricting the size of this queue to 3000 messages.
<UdpAckQsize>
Maximum # of unsent messages stored in message log queue for UDP with
Acknowledgement messages. Valid range is 0-3000. The default is 0, which is
treated as a special value indicating no message size restriction. This is the
equivalent of restricting the size of this queue to 3000 messages.
<UdpAckSmsBckupQsize>
Maximum # of unsent messages stored in message log queue for UDP with
Acknowledgement messages where SMS messaging is allowed as a backup
when UDP messageing is unavailable. Valid range is 0-3000. The default is 0,
which is treated as a special value indicating no message size restriction. This
is the equivalent of restricting the size of this queue to 3000 messages.
Notes
Over-the-air messages sent via the event engine are stored in flash and
indexed via one of the message log queues. Due to indexing restrictions, no
queue can contain more than 3000 unsent messages.
For performance reasons, messages formatted via the event engine re stored
in an array of 256 1000-byte flash files. Indexing for these messages is
maintained in separate flash files (one for each queue).
Normally, the number of unsent messages that can be stored in flash is a
function of the size of the messages. For example, when storing messages
containing only NMEA data, the message log files will be completely filled
after about 2500 messages. Binary messages are typically smaller and take
up less space in the message log files, but are still subject to the 3000
message maximum per queue.
When the message log files are full OR when an individual queue exceeds
3000 messages, the oldest log file is deleted so that newer messages can be
stored in a circular fashion using a new file in the place made available by
deleting the oldest file. For some applications, the message buffers can
contain far more unsent messages than is desired.
The device only saves messages in the message log if the STORE_MSG
(PARAM2 bit 6) is set. Wakeup messages and other messages which do not
have the STORE_MSG bit set will not be stored in the message log. This is a
change from the behavior of other Novatel Wireless devices. (GSM/GPRS
devices will save some messages in the message log depending upon the
network status even though the STORE_MSG bit is not set.)
The purpose of this command is to mark older messages as ‘sent’ so that the
number of messages in the queue never exceeds the threshold set by the
user.
Please note that the values specified in this command are not reflected in the
value calculated for input event 61 (memory full percentage). That
percentage represents the worst case (largest percentage) of either the % of
the size of all unsent messages with respect to the size of all 256 log files OR
the % of unsent messages with respect to the 3000 messages allowed for an
individual queue.
