Caution: MQTT Clients IDs must be unique and if two clients attempt to connect with the same client ID, one will be forcefully disconnected from the server to allow the other client to connect. |

If the server does not receive, at minimum, a PINGREQ message from a client within 1.5 times the Keep Alive, it will terminate the connection and send the client's LWT if it has been defined.
For MQTT Transmission, this is an DEATH message.

If both the Random Startup Delay and the Reconnect Delay are configured, the startup delay for any one client will be the aggregate of the two configured values. For example, with the Random Startup Delay = 10-1000ms and the Reconnect Delay = 1000ms, the startup delay for any one client will be between 1010 and 2000ms |
