Yes. The only chip we have at this moment which does BT Classic is the (non-C, non-S, original) ESP32.
thank you
and still there is no plan for BLE 5.1 or 5.2 ? for audio LE feature ?
I think it canceled to use ble 5.2 in esp32-h2 version !

Hi
I'm confused ! every Bluetooth Documents that I read said: every chip or module or ... that work with BLE will Support Bluetooth Classic(BR/EDR).
you sure S3 doesn't support it?
and I did not study ESP32 C3 datasheet so you mean is it too ?? :cry:

Most of the Bluetooth specifications in Bluetooth SIG documents are optional. It is up to each chip vendor to implement these optional functionalities such as BLE, Long Range, Mesh-Networking, Bluetooth direction finding based on AoA (Angle of Arrival) & AoD (Angle of Departure) including classic BR/EDR for audios are also optional features in Bluetooth.

Hi,
we have developed custom board using esp32DOWD V3 for our product, as we are upgrading our product with new features we have chosen esp32s3(which have more gpio s) and developed custom board which has to support audio streaming over BLE. I have tried A2DP protocol on esp32s3 r2 chip which is not supporting audio streaming, does audio streaming supports on esp32s3?, are there any other latest chip sets in esp32 S series which support audio streaming.

As far as I know, only ESP32 supports classic BR/EDR and A2DP with AAC. The later ESP32-xx are not support. Espressif is focusing on making IoT SoCs right now. You'd better settle with ESP32 modules or wait for a big brother ESP32-P4.
