ST: Sigfox software for STM32 MCUs boosts connectivity choices for IoT-device developers
STMicroelectronics has extended its STM32 software ecosystem with a Sigfox package that simplifies development and gives extra flexibility to connect Internet-of-Things devices to long-range, low-power wireless networks.
The new X-CUBE-SFOX package is ready to use with ST’s B-L072Z-LRWAN1 Discovery Kit, which is already LoRa enabled through I-CUBE-LRWAN embedded software. Developers can now work with either of these established Low-Power Wide Area Network (LPWAN) technologies on the same hardware, and create products that can use the two protocols individually or alternatively. The Discovery Kit features the Murata CMWX1ZZABZ-091 module powered by an STM32L072 microcontroller, a sub-GHz radio transceiver SX1276 from Semtech, and is expandable via Arduino headers to add sensors or other IoT-device functions and capabilities.
X-CUBE-SFOX contains a complete set of Sigfox libraries and application examples for the STM32L0, and can be ported to other microcontrollers in the STM32 family. With over 700 STM32 variants, from ultra-low-power to high-performance lines, developers can leverage unrivaled flexibility to optimize the performance and features of IoT devices that take advantage of Sigfox services including basic connectivity, radio recognition, and GPS-free location. The software’s low memory footprint and efficient CPU utilization minimize demand for system resources, helping to lower bill-of-materials (BOM) costs and power consumption.
The X-CUBE-SFOX software can be downloaded free of charge; the B-L072Z-LRWAN1 Discovery Kit is available now.
