Hi !

Since Bluetooth 5.2, the SIG has designed the Basic Audio Profile, which is designed specifically for audio over BLE. You can read about this profile here : https://www.bluetooth.com/specifications/specs/basic-audio-profile-1-0-1/. This sounds like the profile you should use for inter-compatibility with audio devices on BLE.

Do note that TI does not currently provide an implementation of this audio profile. The customer will have to implement this profile themselves.

The recently released CC2340R5MODA has BLE and UART but no I2S.
The CC27xx devices have BLE, UART and I2S, but TI does not provide a module for these chips.
The CC2650MODA do not support Bluetooth 5.2

The CC2652RSIP / CC2652PSIP / CC2651R3SIPA all have an I2S, BLE 5.2 and UART. You can either chose one of these modules, or use a third party module for the CC27xx.

Kind regards,
Lea

There are also custom BLE implementations of BLE audio that you can find here : https://software-dl.ti.com/lprf/simplelink_cc2640r2_latest/docs/blestack/ble_user_guide/html/voice/ble_voice.html

Depending on the type of product that you are building, a vendor-specific profile like this one could be enough.

Kind regards,
Lea
