Low cost tool enables custom Wi-Fi implementations for the Internet of Things

March 08, 2012 // By Jean-Pierre Joosting
GainSpan® Corporation has introduced SDK-Builder, a web-based tool that enables developers to select Wi-Fi features and build custom binary for their embedded devices, with no IDE tool chain. SDK-Builder, claims to be the first such tool for the embedded Wi-Fi market, reduces development cost for companies designing connected devices based on GainSpan's Wi-Fi modules.

SDK-Builder eliminates the need to use pre-built firmware binary images, but rather allows users to create custom firmware binary images on-demand tailored to their applications. This tool provides a baseline default configuration (essential wireless stack features, WPA/WPA-2 personal security and networking services) and then lets developers choose the additional software features and functionalities by selecting them on a menu. Features include host interfaces, security, provisioning methods, application layer protocols, and over-the-air firmware upgrade, using external flash and other test modes.

In addition, SDK-Builder provides developers with built-in intelligence to eliminate invalid code combinations, a real time binary file size indicator to show total memory usage, and error alerts when memory limits are exceeded.

SDK-Builder can be used with the company's family of certified Wi-Fi modules: the GS1500M is a leading-edge 802.11b/g/n module, while the GS1011M is an ultra-low power 802.11b module which is ideal for battery operated devices.

SDK-Builder is available immediately by purchasing an annual subscription license. The tool is accessible at http://sdkbuilder.gainspan.com.
