STM32 ODE function pack for half-duplex voice streaming over Bluetooth low energy

ソフトウェア入手 データブリーフのダウンロード



FP-AUD-BVLINK1 is an STM32 ODE function pack that performs voice streaming over Bluetooth low energy in a half-duplex configuration. The application runs on the STM32 Nucleo and includes drivers and middleware for Bluetooth low energy (BlueNRG-MS) and MP34DT01-M or MP34DT04-C1 digital MEMS microphones.

The expansion is built on STM32Cube software technology to ease portability across different STM32 microcontrollers. The software comes with sample implementations of the drivers for X-NUCLEO-IDB05A1 plus X-NUCLEO-CCA02M1, when connected to a NUCLEO-F401RE, NUCLEO-L476RG or NUCLEO-L053R8 board.

FP-AUD-BVLINK1 is also compatible with SensorTile (STEVAL-STLKT01V1) and BlueCoin (STEVAL-BCNKT01V1).
