I switched the timestamp query from callingmillis()tomicros(). As per Arduino documentation,this change improved time resolution by 250from 1 millisecond precision to 4 microsecond precision. Since I had time on my mind anyway, I took a research detour to learn how ...

Analyze the timestamps of each set of messages to see how closely the average of the differences corresponds to the configured periodic rates. avgPeriodFast = mean(milliseconds(diff(msgRxFast.Time))) avgPeriodSlow = mean(milliseconds(diff(msgRxSlow.Time))) A plot of the received signal dat...
()is called frequently prior to hard deadlines. The APIos_queryTimeCriticalJobs()can be used to check whether there are any deadlines due soon. Before doing work that takesnmilliseconds, callos_queryTimeCriticalJobs(ms2osticks(n)), and skip the work if the API indicates that the LMIC needs...
