Client ID is the unique identity of the client to the server.
It must be unique when all clients are connected to the same
server, and it is the key to handle message at QoS 1 and 2.
If the client does not get a response after the connection
timeout, the connection will be considered as broken. The
Range: 1-65535
After the client is connected with the server, the client will
send heartbeat packet to the server regularly to keep alive.

QoS 0 – Only Once
This is the fastest method and requires only 1 message. It is also the
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.
