5.
Sending (accumulating) data is done using the +MIPSEND command.
6.
Actual send is done using the +MIPPUSH command, by specifying the IP address and port
number of the destination.
NOTE:
Every +MIPPUSH sets the destination IP address and destination port number for the current
and future transactions. These values are used for the next push if not explicitly overwritten.
The following occurs when creating a UDP/IP connection from the SMC modem (client/server) to
WEB (client/server):
1.
Client side:
– The SMC modem client connects to the 1x network and receives an IP address (using the
+MIPCALL command).
– The SMC modem opens a UDP/IP stack as one of its "sockets" (using the +MIPOPEN and
selecting the protocol UDP).
2.
The SMC modem sends data to the Website, as the Web site’s IP address is known and is
public, and the port number is previously agreed upon.
3.
Sending (accumulating) data is done by the +MIPSEND command.
4.
Actual send is done by the +MIPPUSH command by specifying the Website IP address and
Website port number.
5.
Server side:
– After receiving the first packet from the client, the server knows the IP address and port
number of the SMC modem.
– The IP address and port number for the specific mobile SMC modem should be saved in the
DB.
NOTE:
Every +MIPPUSH sets the destination IP address and destination port number for the current
and future transactions. These values are used for the next push if not explicitly overwritten. FTP
Online Data Mode
The Online Data Mode (ODM) feature, allows the user to transfer raw data (without using the
AT+MIPSEND and AT+MIPPUSH commands) between SMC modem and Network. The data transfers
via established network connection (socket), based on internal TCP or UDP protocol stack. RS232
connection between SMC modem and terminal with Hardware flow control is required for the feature
execution.
A special AT Command AT+MIPODM (instead of AT+MIPOPEN) is used to open a socket in Online
Data Mode. The command provides a set of parameters for the feature configuration and corrects
performance. When a socket is successfully opened in Online Data Mode, all data, comes from
terminal, "as is" is being sent to Network and vice versa: all data, comes from Network, "as is" is
being sent to terminal.
