I was not aware that _any_ Espressif hardware even supported classic bluetooth other than the very first ESP32 (which I am not sure if they're even available).

I was not aware that _any_ Espressif hardware even supported classic bluetooth other than the very first ESP32 (which I am not sure if they're even available). And I was getting around 50ms latency back then (with the original ESP32 and SBC!)
What exactly did you try?
- timothyb89 4mo agoI’m using BLE GATT messaging with an upgrade path to L2CAP CoC channels for clients that support it. Roughly the path is: audio input -> opus encode -> BLE transmit -> smartphone/desktop. The latency floor ends up being ~80ms due to jitter buffer sizing, etc.
- AshamedCaptain 4mo agoWhile this explains the bw limit, I'm still surprised re latency, it sounds really bad even for L2CAP.
