3.5 Ack’ed Mode

UDP is not a 100% reliable connection and occasional reports or command/responses may be

lost. Since all commands have responses, the server can repeat any command to which there is no

response. In order to assure reliable reception of reports, LTE devices can be confi gured

either in Normal or Ack’ed mode to send the reports. In the Normal mode the reports are simply

sent “as is” with no acknowledgment from the server. In the Ack’ed mode every report sent is

expected to be acknowledged by the server by sending back an ACK message back. If

acknowledgement

is not received within the specified timeout, the report is re-sent. If the report is

not acknowledged after the specified number of attempts, it is queued. If acknowledgement is

received after the report is queued (i.e. past timeout of the last attempt), it is ignored.

Report is not considered “complete” until its acknowledgement is received. Thus, if report X is

sent and report X+1 is triggered while waiting for acknowledgement of X, report X+1 will be

queued until such acknowledgement is received and only then sent. The LTE will attempt

to re-send queued report(s) every time a new report is triggered. If there is more than one report
