The Silicon Labs Gecko SDK (GSDK) is a single integrated package of 32-bit IoT product software development kits (SDKs) and Gecko platform. It is the primary tool for development in the Silicon Labs IoT Software ecosystem. It provides many powerful features to offer a seamless experience which includes ultra-low power consumption, strong network reliability, Industry-leading ability to support a large number of nodes, and abstraction of complex requirements like multiprotocol and pre-certification. The GSDK is covered by one of several different licenses with the default license of Master Software License Agreement (MSLA). Silicon Labs also extends over-the-air (OTA) software and security updates to remotely update the devices, minimize the maintenance cost and improve the end-user product experience.
