STMicroelectronics (ST) has added the Sigfox package to the STM32 software ecosystem. This package simplifies development and enhances flexibility in connecting long-range, low-power wireless networks and IoT devices.

The new X-CUBE-SFOX package can be used with ST's B-L072Z-LRWAN1 Discovery Kit, which enables LoRa communication via the embedded software I-CUBE-LRWAN. Developers can choose one of these two Low-Power Wide Area Network (LPWAN) technologies to work on the same hardware, and it is also possible to develop products that use both protocols or selectively use them. This Discovery Kit consists of Murata's CMWX1ZZABZ-091 module powered by the STM32L072 microcontroller and Semtech's SX1276 sub-GHz wireless transceiver, and allows for the addition of functions and capabilities for sensors or other IoT devices via Arduino headers.

X-CUBE-SFOX provides a complete set of Sigfox libraries and includes application examples for the STM32L0. Additionally, it can be ported to other microphone controllers in the STM32 family. Developers can leverage the exceptional flexibility of the STM32 product family, which comprises over 700 models ranging from ultra-low power to high performance lines, to optimize the performance and functionality of IoT devices utilizing Sigfox services, such as basic connectivity, wireless identification, and GPS-free location. This software reduces material costs and power consumption by minimizing requirements for system resources through its small memory footprint and efficient CPU utilization.
