Hi @Gk ,
yes, this kind of application is supported by ST Bluenrg chips, that can be directly connected to ST MEMS microphones.
Specifically, you can refer to the FP-AUD-BVLINK1 function pack, that runs on STM32 and performs voice streaming over Bluetooth low energy in a half-duplex configuration. It includes drivers and middleware for Bluetooth low energy (BlueNRG-MS) and MP34DT01-M or MP34DT04-C1 digital MEMS microphones. You can also interface the supported platforms with the STBLESensor smartphone app.
If you don't want to use an STM32 but just the BlueNRG-1 and BlueNRG-2 devices, you can refer to the STSW-BLUENRG1-DK application and to the STSW-BLUETILE-DK function pack (this last is dedicated to a specific platform, the Bluetile kit), to find examples for the sensor data streaming over BLE, and in particular Voice over BLE communication (for example in the folder: \Project\BlueNRG1_Periph_Examples)
If this has been helpful for you, please let me know selecting this answer as Best for future users.
