製品概要
概要
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 Peripheral module can also stream audio to an Android™ device running the STBLESensor app v 4.2.0 or higher
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.
