French software companies MicroEJ and Witekio are collaborating on a demonstrator for Sigfox connectivity for embedded or IoT projects.
The demonstrator aims to leverage a connection to a Sigfox low-power wide-area network (LPWAN) of a geo-location application running on MicroEJ’s operating system and an ARM Cortex-M evaluation board from ST Microelectronics.
The partnership wants to offer Witekio’s system software integration services to customers choosing MicroEJ for developing their next generation of cloud connected IoT services.
“This project demonstrates how MicroEJ can be used to create connected and interactive applications for cost-effective embedded and IoT devices in record time thanks to MicroEJ OS and associated development tools,” said Fred Rivard, CEO of MicroEJ. “MicroEJ and Witekio offer complementary technologies and skillsets to support the development and deployment of innovative embedded and IoT customer projects.”
The geolocation system illustrates how the Sigfox LPWAN can be used to collect and store location data of connected objects. The demonstrator includes an embedded device prototyped on an ST Microelectronics STM32F7 evaluation kit running MicroEJ OS and connected to the Sigfox network through a Sigbee radio module.
Dedicated embedded applications were developed for MicroEJ OS including a system configuration app, a graphical user interface for live positioning, a system interaction app for triggering position recording through a GPS module, and a data push app for pushing location data over the Sigfox network.
Published location data are stored on Sigfox network backend infrastructure. Data can be collected and observed on a user-friendly map from a mobile application running on Apple iOS or Google Android tablets and smartphones and connected to the backend.
“Witekio is a system software integrator capable of helping customers develop and integrate all their software layers from hardware to the cloud,” said Yannick Chammings, CEO of Witekio. “We enjoy successful collaboration on joint customer projects with MicroEJ on ARM-based microcontrollers and microprocessors. Our companies have complementary expertise and offer tools, technologies and integration services.”
Witekio started 15 years ago under the name Adeneo Embedded, as a precursor of complex and connected embedded systems. The company uses a system level approach, engineering and integrating intelligent systems software for any device from the hardware to the cloud.
MicroEJ is an independent software vendor for the smart digital world. With more than $20m of R&D investment, the company is focused on providing turnkey software to solve the embedded world’s major business problems and to enable application-driven uses and services in the IoT world commensurate with the cost and resource constraints of that world.
