ICYStream and WiFiManager - Initial WiFi credentials unknown ( Moved from wrong repository discussion)

[Ephesian]

Thanks for your previous reply ->pschatzmann/arduino-audio-driver#38

I realised that I had posted in wrong place. I am very new to ESP32 and c++

I am using an AI Thinker AudioKit V2.2 A247 with an E8388, and I can get a Sinewave output

The problem with this is that since I have moved the AudioTools objects into the code, the StreamCopy object copier is not found

src/main.cpp: In function 'void loop()':
src/main.cpp:92:3: error: 'copier' was not declared in this scope
copier.copy();
^~~~~~
src/main.cpp:92:3: note: suggested alternative: 'open'
copier.copy();
^~~~~~
open

here is my sketch.

This is impossible to read: Please use the proper code formatting syntax,

Dont define variables locally that you want to be available across your sketch.

Maybe you should start with some C++ tutorial first...
