The STEVAL-BLUEMIC-1 evaluation board mounts the SPBTLE-1S Bluetooth®SMART application processor compliant with BT specification v4.2. It supports multiple simultaneous roles and can act as a Bluetooth Smart master and slave device at the same time. This BLE wireless battery powered solution also embeds digital MEMS microphone MP34DT05-A (or MP34DT04-C1 in the first generation board) and 3D accelerometer + 3D gyroscope, which render this evaluation board suitable for a wide range of advanced smart applications. The evaluation board comes with a SW development kit that includes the Bluetooth low energy stack, all the drivers for audio and inertial data acquisition, and button and LED management. A ready-to-use BlueVoice library is included as middleware and a sample application is provided to get you started with voice streaming over BLE to an Android or iOS device, running the ST BlueMS apps.
