FP-AUD-BVLINK2 Data brief STM32Cube function pack for full-duplex voice streaming over Bluetooth low energy using Opus compression
●FP-AUD-BVLINK2 is an STM32Cube function pack that performs voice streaming over BLE in a full-duplex configuration using the advanced Opus compression algorithm. The application runs on the STM32 Nucleo and includes drivers and middleware for BLE (BlueNRG-MS) and digital MEMS microphones.
●The software with the suggested combination of STM32 and ST devices can be used, for example, to develop wireless audio communication systems in smart home or wearable applications.
●Thanks to the low bitrates you can achieve while maintaining high voice quality with Opus, combined with the low power features of BlueNRG, you can develop applications featuring very low consumption.
●The same audio codec can be used to implement high quality stereo music streaming.
●The software runs on the STM32 microcontroller and includes all the necessary drivers to use the devices on the STM32 Nucleo development board and expansion boards, as well as on the STEVAL-BCNKT01V1 and STEVAL-STLKT01V1 evaluation boards.
●It also includes the Opus audio codec as the STM32Cube middleware.
●Features
■Complete firmware to implement full-duplex speech communication over Bluetooth low energy (BLE) using Opus compression
■A BlueVoiceOPUS customized profile for audio over BLE, including an easy-to use set of APIs to exploit advanced Opus functionality (source code available)
■Third-party Opus v1.2.1 middleware: an open, royalty-free and highly versatile audio codec that is standardized by the Internet Engineering Task Force (IETF) as RFC 6716
■Digital audio signal acquisition and processing
■Audio out playback through USB or jack connector
■Sample implementation available for X-NUCLEO-IDB05A1 plus X-NUCLEO CCA02M1 connected to a NUCLEO-F446RE or NUCLEO-L476RG, for SensorTile (STEVAL-STLKT01V1) and BlueCoin (STEVAL-BCNKT01V1)
■Easy portability across different MCU families thanks to STM32Cube
■Free, user-friendly license terms
