STM32 Sigfox software expansion for STM32Cube

Sigfox™ is a long range wireless area network allowing low-power sensors to benefit from a planetary network, enabling end devices with low BOM cost.

The X-CUBE-SFOX Expansion Package consists of a set of libraries, open routines and application examples for the Murata CMWX1ZZABZ-xxx module acting as an end device. It includes an application running on the low-power wireless B-L072Z-LRWAN1 Discovery kit.

X-CUBE-SFOX running on the CMWX1ZZABZ-xxx is Sigfox™ ready.

Two examples are additionally provided in the package. They implement respectively: a Sigfox™ modem controlled via AT commands over a UART interface, and a push button that sends environmental sensor data to the Sigfox™ network when pushed.
