Accelerating Innovation through open technologies

To reach the IoT vision of everything connected, interoperability between technologies is necessary to explore new ideas, rapidly build prototypes, and get to market quickly. Sierra Wireless is invested in several open source initiatives to provide IoT developers access to existing hardware and software components so they don’t have to build everything from scratch.
Open Source Software

Legato™ Open Source Linux Platform

Legato simplifies application-level development with a secure application framework, maintained Linux distribution, and feature-rich development environment. Released in open source, Legato future-proofs software investments by offering the flexibility to port the entire stack and applications over to any application processor. With security and connectivity built in, the robust APIs let you connect to any cloud or network enabling IoT developers to focus on building the value-add applications that improve the user-experience.

For Sierra Wireless customers, you can start developing immediately with Legato pre-integrated, tested, and validated inside the application processors of AirPrime WP Series and AR Series.
