Using Bluetooth speakers

[ProHarshit]

Hi. I want to use the espeak project with Bluetooth. Reading the Audio Tools project, I think it is possible. But can anyone suggest me the proper code for that? I am using ESP32 WROOM 32

[pschatzmann]

You can e.g. use an A2DPStream as output class

Can you please suggest the lines I have to change?

Have a look at this example and just change the TTS implementation

Sir, will this code work? I am not able to run my computer for some temp issues.
#include "AudioTools.h"
#include "FileSystems.h"
#include "espeak.h"
#include "AudioLibs/A2DPStream.h"

const char* name = "LEXON MINO L";

AudioInfo from(22050, 1, 16);
AudioInfo to(44100, 2, 16);

A2DPStream a2dp;
FormatConverterStream out(a2dp);
ESpeak espeak(a2dp);

void setup() {
Serial.begin(115200);
espeak.begin();
audio_info espeak_info = espeak.audioInfo();
Serial.println("Starting...");
out.begin(from, to);
auto cfg = a2dp.defaultConfig(TX_MODE);
cfg.name = name;
cfg.silence_on_nodata = true;
a2dp.begin(cfg);
a2dp.setVolume(0.3);
Serial.println("A2DP Started");

void loop() {
espeak.say("Hello world!");
delay(5000);
}

No, you need to send the output from the espeak to out and not a2dp!

#include "AudioTools.h"
#include "FileSystems.h"
#include "espeak.h"
#include "AudioLibs/A2DPStream.h"

const char* name = "LEXON MINO L";

AudioInfo from(22050, 1, 16);
AudioInfo to(44100, 2, 16);

A2DPStream a2dp;
FormatConverterStream out(a2dp);
ESpeak espeak(out);

void setup() {
Serial.begin(115200);
espeak.begin();
audio_info espeak_info = espeak.audioInfo();
Serial.println("Starting...");
out.begin(from, to);
auto cfg = a2dp.defaultConfig(TX_MODE);
cfg.name = name;
cfg.silence_on_nodata = true;
a2dp.begin(cfg);
a2dp.setVolume(0.3);
Serial.println("A2DP Started");

void loop() {
espeak.say("Hello world!");
delay(5000);
}

Is this ok sir?
