MQTT_DEPTH

 

public final static int

This controls the conditions under which trigger messages are written as a result of messages arriving on this queue. With this option, a trigger message is written whenever the number of messages of priority TriggerMsgPriority or greater on the queue equals or exceeds TriggerDepth.

After the trigger message has been written, TriggerControl is set to MQTC_OFF to prevent further triggering until it is explicitly turned on again.
