ESP32 audio to Bluetooth / DIY speaker example Arduino

Sound reproduction using ESP32 via Bluetooth. The Arduino IDE bluetooth example requires only an esp32 board and speakers. #ESP32 audio output - you can create multichannel audio on GPIO25 and GPIO26.

dude, you dont know how you helped me a lot... i was killing myself 2 weeks dont knowing how to use that library + i DIDNT KNOW that esp32 had DAC pins that can play music... i wanna thank you with my whole heart, you are my hero

[@sumitluitel7836]

hey did you try this? Did this work?

[@neoncraft_]

@@sumitluitel7836 yes, it works perfectly fine

[@BarnaclesBailey]

Many thanks for the AWESOME demo video! Simple and to the point, was a great help to understand how it all pieces together :) Going to watch your video that integrates the MAX98357 next!

[@user-sv5hr4fq1d]

can you tell me why I can’t find main in the code from github

[@user-sv5hr4fq1d]

U found it?

[@waka7377]

creo que te falta poner un capacitor a la salida de cada DAC para filtrar la parte continua y además amplificar la señal al menos con un transistor para no quemar la esp32

[@AleksandrIvin]

Nice demonstration! Have you also try any other ways to make sound louder?

[@afyu]

Used a board with an amplifier for sound output MAX98357

[@joshuagardiner9096]

I am using ESP32 c6 and it doesn't seem to work...

[@user-js1im6kc4m]

Nice video😆

[@fantasystudios5628]

hey dude . can you please provide the code for this i can't get it right . please provide it . please

[@DollarJonny]

То самое чуdство когда назвал провода wires кабелями cables в видео об электронике , не понимая в чем разница =)

[@janekkomorowski9046]

Hi, do you know how to resolve error: 'i2s_config_t' does not name a type? I am using the example you showed but this is what i get

[@JehadurRE]

did you fixed it ?

[@VelmuruganG-dr3yd]

Can we hear 8d music with this if I connect and old headphones speakers to it

[@afyu]

a lot of noise in the sound and a weak signal that will not let you shake the headphones

[@ayrusproductions9872]

can i give output to the amplfier for better sound and is there any noise like humming or something

[@afyu]

You can connect an amplifier. But I think the noise will remain

[@mradulbhardwaj3147]

How to Serial communicate along with Bluetooth speaker ??

[@mradulbhardwaj3147]

Kindly reply ?

[@user-sv5hr4fq1d]

Where in ur code main?

[@OmegaINDcreates]

How would I increase the quality of the audio so I avoid that awkward buzz found in your testing?

[@afyu]

It is better to use output via I2S. There's no noise.

[@TheOldKid]

I must have gremlins. I have downloaded more stuff trying to do this and I keep getting no file exist for audiotools and the bluetooth. I must be doing/did something wrong somewhere

[@TheOldKid]

Got it to upload. Looks like code has changed a little. No doubt it's on my end but my esp is visible to my phone but won't connect.

[@SJCB21]

Can you somehow add startup sound? Modify power off sound?

[@afyu]

you can add a buzzer summen or play a short music file from memory

[@SJCB21]

@@afyu how

[@xdon6549]

is it possible to also use nodemcu ?

[@afyu]

yes nodemcu esp32

[@tonymitmakaroni527]

Is it possible to increase the volume, its very silent. Very cool video!

[@afyu]

Increase the volume only by using an additional amplifier

[@syedmohamadadil3848]

Hello, is the song played from the phone?

[@afyu]

esp32 is connected via Bluetooth to a smartphone. The sound itself is from esp32.

[@syedmohamadadil3848]

Yes, but is the phone the source of the song?

[@PoorPlyser]

​@@syedmohamadadil3848 The songs he used are at the bottom of the description.

[@PoorPlyser]

​@@syedmohamadadil3848oh, nvm. He connected via bluetooth from the phone to the esp32. But chose the song from the phone

[@mehteshwarsinghgabbi4946]

Hello brother I saw full video on esp mcu based Bluetooth speaker I want to install google assistant and Alexa code in my esp mcu can you help me in installing google assistant and Alexa voice commands and code in esp32 based mcu and make a video step by step on youtube

[@afyu]

I do not plan to shoot such a topic at the moment. It may be useful on this topic www.arduino.cc/pro/software-speech-recognition-engine/

[@didierdurand7334]

Connect a speaker directory on gpio is a stupidity

[@pascayogamohammadihshongif5190]

can this bluetooth connect to laptop?

[@afyu]

yes you can connect

[@K.O.W]

Can you leave a link to the code?!?!

[@afyu]

github.com/pschatzmann/ESP32-A2DP

[@emran.e]

please make a vidio wifi audio receiver & transmitter for 5.1 sarrainodu sound

[@Marc_Wolfe]

tHAT GITHUB LINK IS CLUTTERED GARBAGE.

[@afyu]

Everything is fine github.com/pschatzmann/ESP32-A2DP

[@Marc_Wolfe]

Arduino begs to differ. # error "ESP32C3, ESP32S2, ESP32S3 do not support A2DP"

[@afyu]

in the video a board with esp32 was used. I haven’t tested it on other boards with modifications.

[@Marc_Wolfe]

Garbage library that lacks support, and is cluttered with nearly identical example code.
