Utilise esp32 bluetooth as another audio output/control for Karadio

[MarcLuc]

Another feature worth looking into is using bluetooth wireless headphones as another possible audio output and playback control? bt headphones like sony wireless headphones MDR-ZX770BN... That way user/ listener can adjust volume or channel via BT headphones. Let me know if you need someone to test!

I can't. Not enough sram to include BT in code.
I will try with the esp32 WROVER.

I am currently looking into A2DP SRC capabilities as well (ESP32 as bluetooth playback device). Maybe you could use an external SRAM chip, like IPS6404L-SQ-SPN for example? See https://esp32.com/viewtopic.php?t=5450

I join the question. It would be great to add A2DP. Maybe you can fork project only with A2DP or make a setting like #define I2S #define A2DP e.t.c. for select only needed feature, but not all?

It is in progress.
A2DP sink and source for wrover esp32
Planned in 2019....

For pure A2DP sink, some other project are available yet on wroom

Any progress so far?
