OK, so I’m still figuring out how to time the sending of my messages to the cloud.
I read the article you suggested “Sending MQTT messages within rate limits”,
but basically none of the examples provided there work for me.
I’ve narrowed it down to this: if I use only “CAYENNE_OUT(n)” functions with virtualWrite inside
it works perfectly, I get the messages in the cloud every 15 seconds.
But if I use any other kind of methods to send the messages, like “CAYENNE_OUT_DEFAULT()”,
of the if millis code in the loop, or a timer function, or the if state changed code in the loop, then I never get any messages in the cloud, and the device disconnects after about 50 seconds then reconnects after 30 seconds continually. In the code above, If I change just just the one line of code, from “CAYENNE_OUT(0)” to “CAYENNE_OUT_DEFAULT()” then it does not work anymore.
I’ve tried to debug it, and when it does not work in the console I see about 5 commands “AT+CIPSEND=1,40” one after another without anything in between,
but with the working code every command like that is followed my a message to the cloud.
Any advice ? Thank you.
