It's possible to force the connection of remote device to server after a long inactivity period of time ( 1 hour to 1 week ). If no event occurs for long time, the unit will perform anyway a connection at specified time interval.

The same behavior can be achieved using the AT#CON or  AT#SYNC command within a scheduled operation ( be careful of interactions with WEB > service > maxtime ).

WEB > service > maxtime elapsed without local events, connection is due, or

scheduled operation (single or recursive) with command  AT#SYNC

The device opens the connection to server - if not already connected - uploading data and downloading pending commands (if any), leaving the connection open.

The connection could be closed by network operator after an inactivity period.
