20 Nano Socket iWiFi G2 N2 Datasheet 9. Evaluation Board The II-EVB-363-G2-N2 evaluation board enables you to evaluate the Nano Socket iWiFi G2 N2 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 iChips 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 Programmers Manual on Connect Ones website. To help you evaluate the Nano Socket iWiFi G2 N2, Connect One supplies the iChip Config Utility. This is a Windows-based application that contains intuitive dialog boxes to fully configure iChip CO2144. It doesnt 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 iChips websites, entering SerialNET mode, and more. The latest iChip Config Utility version and user manual can be found on Connect Ones website under the Support section. On board connectors allow a choice of Host interfaces:
