This development effectively combines Bluetooth low energy features with the connection capacity of Sigfox wide-area networks. It includes examples and recommendations regarding the simultaneous use of the two protocols. Very low active RF and MCU current, and low-power mode current consumption provide excellent battery lifetime, allowing operation with coin cell batteries and energy-harvesting applications. The STEVAL-FKI001V1 evaluation board uses the Arduino interface to help development, as it is compatible with ST Arduino shield boards featuring MEMS motion sensors, environmental sensors, and Time-of-Flight (ToF) ranging sensors.
