AWS IoT ExpressLink encapsulates security and cloud connectivity into a communication module, simplifying the development of embedded applications for IoT devices. Pairing FreeRTOS with AWS IoT ExpressLink helps developers focus on the differentiated value of their IoT devices rather than wrangling with provisioning and connectivity code. A serial interface to an AWS IoT ExpressLink module, along with some simple AT commands, are all that’s needed to quickly connect to AWS from an embedded application using FreeRTOS.
