the first connection is failed, it will retry to connect to the server up to the max. reconnect
times. Each retry will be separated by the reconnect “interval”.
3) GPRS connect once
While using this mode, the unit will connect to the server when there is a report to send (but
only try once). If it is not successful, the report will be stored and sent out in the next
successful connection. Disconnect GPRS connection when report sending is completed.
4) Reduce GPRS dialup method
Parameters: On/Off, Max. reconnect times, connect delay
If this method is used, the unit will reduce the GPRS dial-up connection when the dial-up is
failed after number of times. User can define the delay time for the unit before try to
reconnect to the server. If there is trigger report, the unit will connect to server immediately.

Keep alive
Keep alive procedure
Parameters: On/Off, and interval / retry times. In order to keep connection in GPRS
network, the unit can be set to send short keep alive report to the server in order to prevent
the disconnection from the mobile service provider.
Send reports after a successful keep alive ACK. Parameters: On/Off.
If you select this function, all the reports will only be sent out after a successful keep alive
ACK. (So if your keep alive time is shorter then select this function will be OK.) This
function is very useful while using UDP to prevent report lost.
Send a keep alive packet right before a due reports if no data stream within certain time:
Parameters: On/Off, and idle time.
Some GSM provider might cut connection, if there is no data within certain time. It might
result report lost in this “fake connection” duration. For example, you can set parameters in
this region, ex 20 mins. (it means if the unit did not send any data in this 20 mins (including
keep alive or normal reports) ), then it will send a keep alive packet to check if the GPRS
connection is valid or not. If not, it will actively reconnect to GPRS network.
