COMM history fields confusing


geoffm Aug 24, 2011 05:03 PM

We've connected to our loggernet server using the loggernet sdk. We're storing the comm history into our database but I'm a little confused as to the description of the fields (Attempts, Retries, Failures).

Our sensors record data once a minute. That data is transmitted every ten. When I receive a new comm record I often see something like (A=13, R=0, F=0). Why are there 13 attempts? If I only connect once every ten minutes, shouldn't this read 1?

Thanks in advance

Each record in the Comms history tracks the number of "S", "W", and "F" messages that are reported in the comms log for a ten minute interval. The act of polling a datalogger for data is an operation that takes not one but several interactions with the datalogger. For CR10X final storage collection, for instance, there are several commands that need to be given and acknowledged before we can judge collection to be successful for a given final storage area. Each of these interactions has a chance of failure so logging a success on that operation in the comms log is worthwhile.
