!MCO:PRO:RC=1 in debug logs

[alowhum]

When enabling MyDebug on a node I'm working on, I sometimes see bursts of this:

100776 !MCO:WAI:RC=1
100780 !MCO:PRO:RC=1
100782 !MCO:PRO:RC=1
100784 !MCO:PRO:RC=1
100786 !MCO:PRO:RC=1
100788 !MCO:PRO:RC=1
100790 !MCO:PRO:RC=1
100792 !MCO:PRO:RC=1
100794 !MCO:PRO:RC=1
100796 !MCO:PRO:RC=1
100798 !MCO:PRO:RC=1
100800 !MCO:PRO:RC=1
100802 !MCO:PRO:RC=1
100804 !MCO:PRO:RC=1
100806 !MCO:PRO:RC=1
100808 !MCO:PRO:RC=1
100810 !MCO:PRO:RC=1
100812 !MCO:PRO:RC=1
100814 !MCO:PRO:RC=1
100816 !MCO:PRO:RC=1
100818 !MCO:PRO:RC=1
100820 !MCO:PRO:RC=1
100823 !MCO:PRO:RC=1
100825 !MCO:PRO:RC=1
100827 !MCO:PRO:RC=1
100829 !MCO:PRO:RC=1
100831 !MCO:PRO:RC=1
100833 !MCO:PRO:RC=1
100835 !MCO:PRO:RC=1
100837 !MCO:PRO:RC=1
100840 !MCO:PRO:RC=1
...etc...
102779 !MCO:PRO:RC=1

I don't see anything about this on the forum. I did find that MCO means "MySensors core".

It seems to happen during the wait part of the code below, which is in the receive function:

    // Change relay state
    desiredState = message.getBool()?RELAY_ON:RELAY_OFF;
    if(desiredState == RELAY_ON){
      send(relay_message.setSensor(message.sensor).set(RELAY_ON)); // Send on state
      digitalWrite(RELAY_1, RELAY_ON);
      Serial.println(F("Turning on"));
      wait(PULSELENGTH);
      digitalWrite(RELAY_1, RELAY_OFF);
      Serial.println(F("Turned off"));
      //send(relay_message.setSensor(message.sensor).set(RELAY_OFF)); // Send off state
    }
    send(relay_message.setSensor(message.sensor).set(RELAY_OFF)); // Send off state
	}

Perhaps I should keep the receive function as brief as possible?

Yes, that was it. I love it when I answer my own questions

@alowhum the warning is emitted at https://github.com/mysensors/MySensors/blob/dd91aeb9c30dbd658bd02c34445669a7cd996c0f/core/MySensorsCore.cpp#L60

Calling wait and send from within receive can cause recursive loops, which is why the log message is shown.

[alowhum]

Ah, interesting, thanks for the explanation.
