    In normal applications, DTU will always try to connect with the center even if the 

center has problems or closed. To reduce these unnecessary wireless data flow, you can 

configure the “Connect Retry Times” and “Reconnect Time Interval” items. When 

DTU fail to connect to the center with the configured Retry Time, It will sleep 

“Reconnect Time Interval” time, then start next retry.
