data for the defined Idle Time period. Bear in mind that data could be continuously sent
from the modem to the connected device, but if nothing is received back, the modem
will disconnect. If the modem is connected as an auto-connect client then it will try to
reconnect to the server once it has disconnected.
TCP Connect Message:
The TCP connect message function allows for sending either a
custom string or the IMEI number over the socket connection when it is established. If the
field is left blank then the IMEI number of the modem will be sent, otherwise the custom
message, up to 32 characters.
Client connect timeout:
Define the number of retries for the modem to connect to a
remote TCP Sever. This setting is only valid when modem is doing automatic
reconnection.
UDP Session Control
To enhance the reliability of UDP IP Stack communication and control over the UDP
activity and data communication, the user can enable or disable keep alive in
conjunction with the Network Dormant period or alternatively specify Wake up time in
seconds.
Wake up feature will send dummy UDP packets prior to sending any data received via
serial port to setup a channel with the network. The modem will send dummy packet
twice as per timing set, followed by the actual data. This is to ensure the UDP data is not
lost.
Network Dormant Period
: By default, the network puts the modem in dormant or standby
mode within 20 seconds of no data activity.
Keep Alive : This sends a dummy UDP packet prior to modem going dormant and this is
based on the Network Dormant Period, this packet will be sent only if the modem
doesn’t send any data over the wireless network for the Network Dormant period.
Wake Up: Wake up feature will send dummy UDP packets prior to actual data, this wakes
up the communication channel and guaranties sending the complete UDP data packet
to the receiving end. Enabling this could lead to additional delay in data transfer due to
modem sending a dummy packet first to initialize the UDP connection with remote site.
FTP Client
