Is there anything provided by ST about Bluetooth LE audio?

[승양.1]

Hello

I'm going to use BLE to make a Bluetooth speaker that is connected to a cell phone.

As far as I know, I need to use I2S to use audio output, is there an MCU that supports BLE and I2S communication?

And can I know an example or something to refer to?

Thank you.

Hello @승양.1 and welcome to the STM32 Community =)

There is a large selection of STM32 microcontrollers which may answer your request.

I advise you to use the ST-MCU-FINDER tool (integrated also in STM32CubeMX) that allows an easy search of MCU with multiple criteria to ensure the selection of the right MCU.

Note that Audio over BLE is a pretty recent addition to the Bluetooth specs - are there many (any?) phone which support it yet?

" As far as I know, I need (sic) to use I2S to use audio output"

You don't need to - there are plenty of other ways to transport audio.

"can I know an example or something to refer to?"

putting "st ble audio" into google, the very first hit is:
