The MQTT (Message Queue Telemetry Transport) library provides a lightweight publish/subscribe (or PubSub) messaging protocol that runs on top of TCP/IP and is often used in Machine to Machine (M2M) and Internet of Things (IoT) use cases. Resetting a timer results in the timer recalculating its expiry time so the expiry time becomes relative to when the timer was reset, and not when the timer was originally started. Therefore, calling a message buffer API function that places the calling task into the Blocked state can change the calling task’s notification state and value.
