The BLUEMICROSYSTEM2 expansion software package for STMicroelectronics’ STM32Cube allows for the reading and displaying of real-time environmental sensor data, digital microphone levels, battery level, voice communication over Bluetooth low energy (BLE) and acoustic source localisation information with a dedicated BlueMS app for Android/iOS.
The package implements application level functions based on the BLE protocol and enables communication with Android and iOS devices. Developers can use it to prototype applications with Android or iOS services and transmit real-time sensor data.
The software includes the drivers for the embedded STM32 Nucleo expansion board and STEVAL-STLKT01V1 development kit devices, and comes with a sample solution to kick-start development. The drivers abstract low-level hardware details, so middleware components and applications can access the sensors in a hardware-independent manner and low-power strategies reduce system power consumption to a few microamps.
