most unreliable transfer mode.
QoS 1 – At Least Once
This level guarantees that the message will be delivered at least once,
but may be delivered more than once.
QoS 2 – Exactly Once
QoS 2 is the highest level of service in MQTT. This level guarantees that
each message is received only once by the intended recipients. QoS 2 is
the safest and slowest quality of service level.
