The Connect One Mini Socket iWiFi module from TDC is designed to offer a secure connection between embedded applications and a WLan.

Features include extensive security features – such as an on-chip firewall protecting the application from incoming Internet traffic. The module is fully loaded with all internet protocols and parameters.

In order to minimise design-in overhead, the module offers a AT+i SerialNET ‘plug and play’ operating mode for instant serial to IP bridging, without any need to make changes to the host application.

The only support required from the host design is a header to connect the module to the target board, and a suitable antenna attached to the on-module SMA connector, no TCP/IP or WLan stacks are required on the host.

The full feature set of the module is extremely extensive, for developers with more specific requirements. It includes support for up to 10 simultaneous TCP/UDP sockets, two listening sockets, a web server with two websites, SMTP and POP3 clients, MIME attachments, FTP and Telnet clients. 

The security of the module supports SSL3/TLS1 protocol for secure sockets, and HTTPS FTPS protocols as well as WEP, WPA and WPA2 Wi-Fi encryption.
