10. Evaluation Board
The II-EVB-365-G2 evaluation board enables you to evaluate the Nano WiReach SMT G2 without
changing anything in your current development environment. Using a simple Windows-based
application on a PC, you can issue AT+i commands.
AT+i commands are used to configure parameter values into iChip’s flash memory and activate
Internet tasks such as email send, sockets, FTP sessions, configuration, and more.
A full description of AT+i commands can be found in the AT+i Programmer’s Manual on Connect
One’s website.
To help you evaluate the Nano WiReach SMT G2, Connect One supplies the iChip Config Utility. This
is a Windows-based application that contains intuitive dialog boxes to fully configure iChip CO2144.
It doesn’t require any knowledge of AT+i commands. It also contains local firmware update tools.
The iChip Config Utility allows you to perform specific Internet communication tasks such as sending
and receiving emails, activating iChip’s websites, entering SerialNET mode, and more. The latest
iChip Config Utility version and user manual can be found on Connect One’s website under the
Support section.
On board connectors allow a choice of Host interfaces:
x RS232 COM port
x SPI
x USB Device
