What i'm trying to do is a web radio with BT speaker capabilty using ai thinker ESP32 audio kit.
Basically i have to macro state one, connect to wifi and play web radio, second one switch off wifi, switch on bluetooth and wait BT connection.
I've done this easy sample to better explain (after the code some log):

#include <Arduino.h>
#include "AudioBoard.h"
#include "BluetoothA2DPSink.h"
#include "OneButton.h"
#include "WiFi.h"
BluetoothA2DPSink *a2dp_sink;
OneButton KEY_1(36);
const char* ssid_1     = "SSID";         // The SSID (name) of the Wi-Fi network you want to connect to
const char* password_1 = "PWD";     // The password of the Wi-Fi network

enum MachineStates {
    WIFI_START,
    WIFI_WAIT,
    WIFI,
    BT_START,
    BT
};
MachineStates currentState = WIFI_START;
void changeMode();
i2s_pin_config_t my_pin_config = {
    .mck_io_num = 0, //I2S_PIN_NO_CHANGE,
    .bck_io_num = 27,
    .ws_io_num = 25,
    .data_out_num = 26,
    .data_in_num = 35 //I2S_PIN_NO_CHANGE
};
void setup() {
        Serial.begin(115200);
    while (!Serial) {
    ;
    }
    CodecConfig cfg;
    cfg.input_device = audio_driver::ADC_INPUT_NONE;
    cfg.output_device = audio_driver::DAC_OUTPUT_ALL;
    cfg.i2s.bits = audio_driver::BIT_LENGTH_16BITS;
    cfg.i2s.rate = audio_driver::RATE_44K;
    cfg.i2s.fmt = audio_driver::I2S_NORMAL;
    AudioKitEs8388V1.begin(cfg); 
    AudioKitEs8388V1.setVolume(75);
    KEY_1.attachClick(changeMode);
    i2s_pin_config_t my_pin_config = {
        .mck_io_num = 0,
        .bck_io_num = 27,
        .ws_io_num = 25,
        .data_out_num = 26,
        .data_in_num = 35
    };
}

void loop() {
    KEY_1.tick();
    if (currentState == WIFI_START)
    {
        Serial.println("WIFI Start!");
        WiFi.enableSTA(true); //Needed to switch on WIFI?
        WiFi.mode(WIFI_STA);
        WiFi.begin(ssid_1, password_1);
        currentState = WIFI_WAIT;
    }
    if (currentState == WIFI_WAIT)
    {
        if (WiFi.status() == WL_CONNECTED)
        {
            Serial.println("WIFI connected!");
            currentState = WIFI;
        }  
    }
    if (currentState == BT_START)
    {   a2dp_sink = new BluetoothA2DPSink();
        a2dp_sink->set_pin_config(my_pin_config);
        a2dp_sink->start("MyMusic");
        Serial.println("BT started!");
        currentState = BT;
    }
}

void changeMode()
{
    if (currentState == WIFI)
    {
        currentState = BT_START;
        WiFi.disconnect(true, true);
        delay(1000);
    }
    if (currentState == BT)
    {
        currentState = WIFI_START;
        a2dp_sink->disconnect();
        a2dp_sink->end(true);
        delete a2dp_sink;
        delay(1000);
    }
}
