I am working with the LM3S6965 device. I developed a small web server for configure the parameters of my application. With the cable interface eth all seems ok (.....) Now I would like to add a WiFi connection. I'm looking for the wifi module, but often the module include their own tcp stack with limited configuration and can not support multiple connections (I need 12 TCP connections available) The WiFi module with HTTP server function are more expensive for my application. I need a simple radio module with UART connection (The unique SPI interface is busy with display, serial flash ...) without the TCP stack on it and can exchange data at the same level of the MAC device microcontroller. Someone knows a WiFi module with these characteristics I also have a second solution by updating the device to the Stellaris 9000 series and using a normal wifi pendrive connected to the USB host port. But I do not know if the USB pen WiFi should be standard (such as disk mass storage) or anyone who can create a proprietary interface.
An option for you may be the CC3000 802.11bg solution. See below information. The interface is not UART, but SPI.

Hi,
I got this reference from one of the forum. You can check with WhizNets. They seems to have WiFi module and TCP/IP core and other network software available. You can buy as per your requirement.
