How to enable debug on ESP32

[SamuilDimitrov]

Hello im trying to run the WebSocketClientSocketIOack example and connect it to a flask server. But every time i try to run it i get this in the Arduino IDE:

[IOc] Disconnected!
[IOc] Disconnected!
[IOc] Disconnected!
[IOc] Disconnected!
[IOc] Disconnected!
...

How to enable the debug output?

I added

#define DEBUG_WEBSOCKETS
#define DEBUG_WEBSOCKETS(...) Serial.printf( __VA_ARGS__ )

and

USE_SERIAL.setDebugOutput(true);

and that outputs in the Arduino IDE this:

[SETUP] BOOT WAIT 4...

How to make mu output like this: #725 (comment) ?

[Links2004]

for platform IO you can use:

build_flags = -D DEBUG_ESP_PORT=Serial

It would greatly help if this piece of information can be added to the README.md or to the source.
