Re: ESP32 Webradio

The problem is that Bluetooth consumes a lot of RAM, and the web radio needs a lot of it, especially for AAC. It is currently not possible to dynamically allocate and de-allocate the Bluetooth memory, which makes switching between the two modes during runtime impossible. You might get around this if...
