This SW has been replaced by FP-SNS-MOTENV1

The BLUEMICROSYSTEM1 expansion software package for STM32Cube lets you read and display real-time inertial and environmental sensor data through an Android™/iOS™ app.

The package implements application level functions based on the Bluetooth low energy protocol and enables communication with Android/iOS devices. Developers can use it to prototype applications with Android/iOS services, and transmit real-time sensor data with ease.

The software runs on the STM32 microcontroller and includes drivers that recognize the Bluetooth low energy (BlueNRG) hardware and sensor devices. The expansion is built on the STM32Cube framework for STM32 microcontrollers and comes with a sample implementation to kick-start development.
