FP-AUD-BVLINKWB1 X-NUCLEO-CCA02M2 P-NUCLEO-WB55 STM32Cube function pack for STM32WB MCU featuring advanced audio streaming over Bluetooth 5.0 using Opus codec
■The X-NUCLEO-CCA02M2 expansion board has been designed around MP34DT06J digital MEMS microphone. It is compatible with the ST morpho connector layout and with digital microphone coupon boards such as STEVAL-MIC001V1, STEVAL-MIC002V1 and STEVAL-MIC003V1.
■The X-NUCLEO-CCA02M2 embeds two MP34DT06J microphones and allows synchronized acquisition and streaming of up to 4 microphones through I²S, SPI, DFSDM or SAI peripherals.
●Key Products on board
■Is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface.
●FP-AUD-BVLINKWB1 Software
■FP-AUD-BVLINKWB1 is an STM32Cube function pack that performs full-duplex voice streaming or stereo music streaming over BLE using the advanced Opus compression algorithm. The application runs on the P-NUCLEO-WB55 and includes drivers and middleware for BLE and digital MEMS microphones.
■Sample implementation available for X-NUCLEO-CCA02M2 connected to a P-NUCLEO-WB55
●Key features
■Complete firmware to implement full-duplex audio or stereo music streaming over Bluetooth 5.0 using Opus codec for both encoding and decoding
■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 v1.3 (downloadable from http://opus-codec.org/) 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 and Audio out playback through USB
■Compatibility with ST BLE Sensor app to perform audio streaming at 16 kHz and speech to text, or to stream stereo music @48kHz for devices supporting BLE 4.2 or higher
■Free, user-friendly license terms
