(underscore character) + “the last 6 digits of the MAC address”
and cannot be changed.

authentication. The length should be no more than 63 characters.

Reconnection
Interval
The time interval between attempts by the ET-2200 module to
connect to the broker if a connection failure occurs. The valid range
is 5 to 65000 seconds
10(s)
Keep Alive
Interval
The keep-alive mechanism is provided to ensure that both the
client and the broker are alive and the connection is still open.
If a Client doesn’t send any messages during the Keep Alive period,
it must send a PINGREQ packet to the broker to confirm its
availability. The broker must reply with a PINGRESP packet to also
indicate its availability. The broker will disconnect a client, which
doesn’t send a PINGREQ packet or any other message within one
and a half times of the Keep Alive Interval. The valid range is 5 to
65000 seconds.
20(s)
Main Topic
Name
The Topic Name is a combination of the Main Topic Name and the
Sub Topic Name. The Main Topic Name can be empty. The same
part of the Topic Names can be entered in the Main Topic Name
field to improve the processing efficiency of all Topic Names. A
shorter Topic Name also improves processing efficiency.
