Is there a way to use esp32 as bluetooth host and client at the same time

[spacebiker]

I need to connect smartphone to esp32 and send audio stream, but esp32 I also want to connect with headphones and send audio. So for smartphone esp32 is client, but for headphones it is host. Is it possible to make two connections like this?

True wireless headphones use a custom implementation to stream audio to two headphones at the same time - typically the stream is sent to one headphone, when then forwards the audio stream to the other headphone. You could try research that, I am unaware of any open source implementation.

Good luck!
