Bluetooth for Wifi credential

[flashdato]

I am building wifi speaker and at this point, I need to be able to write wifi credentials on the board.

I have found this code example BUT I can not integrate it into my Wifi Speaker module

`

#include "AudioTools.h"
#include "AudioCodecs/CodecMP3Helix.h"
#include "AudioLibs/AudioBoardStream.h"
#include "BluetoothSerial.h" //Header File for Serial Bluetooth, will be added by default into Arduino
#include <EEPROM.h>
#include "WiFi.h"

const char *urls[] = {
"https://tale-server.onrender.com/stream"
};

ICYStream urlStream(ssid, pass);
AudioSourceURL source(urlStream, urls, "audio/mp3");
AudioBoardStream kit(AudioKitEs8388V1);
MP3DecoderHelix decoder;
AudioPlayer player(source, kit, decoder);

float volume = 1;

//bluetooth parameters

String buffer_in;
unsigned long previousMillis = 0;
byte val;
int addr = 0;
byte indS = 0;
byte indP = 0;
String stream;
byte len = 0;

String temp2;
unsigned int interval = 20000;

void next(bool, int, void *) {
player.next();
}

void up(bool, int, void *) {
volume = volume + 0.1 > 1 ? 1 : volume + 0.1;
player.setVolume(volume);
}

void down(bool, int, void *) {
volume = volume - 0.1 < 0 ? 0 : volume - 0.1;
player.setVolume(volume);
}

void previous(bool, int, void *) {
player.previous();
}

void stopResume(bool, int, void *) {
if (player.isActive()) {
player.stop();
} else {
player.play();
}
}

// Arduino setup

}
// Serial.println(stream);

}`

this code could be awful so tell me if there is example or some other project on ESP32

I don't understand you!
If you do the authentication outside of the ICYStream or URLStream you just don't provide any login parameters!
I just added this functionality so that I don't have to code the wifi login functionality in each sketch.

You can save some lines of code if you provide the password and ssid via the corresponding methods...

[pschatzmann]

I am afraid I still don't understand your problem that you have with my library!

[flashdato]

Basically I want it to wait for me it is starting before setup and code I am adding needs setup function to get wifi credentials

How can I jump over that basically delay initializing ur library and wifi

[pschatzmann]

You can move the logic into the loop

[flashdato]

No because than other functions for example volume up wont work because it needs player defined

[pschatzmann]

You will need to manage the state and not call any functionality which is not available yet!
Even the login should be in the loop and be executed whenver we are not logged in yet or lost the connection
