ESP32-S3 Bluetooth source support

Postby unmjiox » Sun Mar 19, 2023 12:08 pm

Hi, I am trying to use an ESP32-S3 as a bluetooth source.

I tried compiling the pipeline_bt_source from esp-adf, but it does not compile with ESP32-S3 as a target. Then I noticed that only boards with ESP32 as marked as compatible in the compatibility chart.

Why is that ?
Is there a way to make this example work on an ESP32-S3 ?
Thank you

Likely because that needs Bluetooth Classic, and the ESP32 is the only chip that supports that.

Hi, thanks for the reply.
Bluetooth classic, as opposed to only Bluetooth LE ?
Weren't all the ESP32 chips supposed to be similar in functionality ?
At docs.espressif.com, if I select ESP32-S3 I can still see a section about bluedroid under "Bluetooth API"

I don't know where you got that idea?

Yes, on ESP32-S3 chips you'd only use the BLE parts of Bluedroid.
