Overview
Connect One’s II-EVB-630W offloads IP connectivity tasks from a host processor or
device. II-EVB-630W supports effortless integration of many upper-layer Internet
protocols using either AT+i™ commands or the iChipConfig Utility, both of which are
described in this document.
II-EVB-630W features include the ability to stream data over TCP or UDP sockets (up
to 10 simultaneous active sockets are available) and manage two listening sockets. A
secure socket (SSL3/TLS1) is fully supported. Additional features include the ability
to send and receive emails with or without attachments, a built-in web server with
two internal websites, one for remote control and management of the II-EVB-630W
and the other for the device; HTTP, FTP, and Telnet clients; and the SerialNET™
(Device Server) mode, a plug-and-play operating mode that enables the connection
of any device with an RS232 interface to the Internet without changing anything on
the device’s hardware or software.
1.1
iChip CO2128SEC — The II-EVB-630W Internet
Engine
The host processor communicates with the II-EVB-630W via Connect One’s high-
level AT+i command set. AT+i commands are simple ASCII characters that are sent
across the RS232 interface. The AT+i Application Programming Interface (API)
requires writing just a few lines of code on the host processor to implement Internet
connectivity.
AT+i commands make it very easy to configure, test, and implement high-level
Internet protocols with virtually no understanding of TCP/IP or other Internet
protocols. Using AT+i commands, the device only needs to tell the II-EVB-630W
what task to perform, but not how to perform it. For example, if the device has to
send textual email, after a one-time short configuration of subject, recipient, mail
account, etc., the device sends AT+iEMA:<lines of text>.
The iChip CO2128SEC inside the II-EVB-630W establishes a connection or uses the
existing one, builds the email (headers and content), connects to the SMTP server
and sends the email. A status report is sent to the device upon completion. All these
actions are completely hidden from the device and only require sending a few
characters in addition to the email content. This mode of operation is applicable for
all features of the II-EVB-630W.
1.2
How to Use this Manual
iChipConfig Utility is a front-end Windows-based user interface for the AT+i
commands. The iChipConfig Utility, combined with the II-EVB-630W, enables quick
and full product configuration, serial-based and Web-based updating of firmware,
and packaging of a website and parameters file. This functionality is achieved from
any device, machine, or system.
