esp32-audio-station

An ESP32 bluetooth speaker and web radio, inspired by KitchenRadio and my previous bluetooth and web radio projects. That project was made thanks too CelliesProjects/ESP32_VS1053_Stream and ESP32-A2DP libraries ! 🙏

Features

• 2 modes : Web Radio or Bluetooth receiver
• mp3 and aac decoding (depends of VS1053 module)
• OLED screen displaying radio, songs, volume
• fetch radios from a json file (to easily update them)
• IR remote (next / previous / volume + / volume - / mute / source)

Status

I wasn’t able to switch correctly from bluetooth to wifi (not enought RAM when enabling wifi). So I store mode in preferences and reboot ESP32... 😐 When it reboots, it checks for mode and starts bluetooth or wifi.

Hardware

• ESP32-WROOM-32D/ESP32-WROOM-32U with Antenna
• VS1003B VS1053 MP3 Module Development Board (make sure it decodes AAC for better stream quality)
• 2.4" 128x64 OLED I2C SSD1309 Display Module
• IR receiver
• IR remote (from an old DVD player)

Connections

ESP32	VS1053	OLED	IR
GND	X	X	G
5V	5V		R
3.3V	3.3V
IO18	SCK
IO19	MISO
IO23	MOSI
EN	XRST
IO5	CS
IO16	DCS
IO4	DREQ
IO21		SDA
IO22		SCL
IO27			Y

Don’t use GND next to 5V ! Uploading will crash

From that example.

Configuration

Copy parameters.h.dist to parameters.h and change it to your settings.

⚠️ Web Radios are fetch from a JSON file. You'll need to create a JSON file containing web radios name and URL (see WebRadios.h) and host it somewhere on the internet.

Note : some VS1053 board aren't able to decode aac streams. You can usually find mp3 alternative (or change board).

Librairies

• paulgreg/ESP32_VS1053_Stream_raw, forked from CelliesProjects/ESP32_VS1053_Stream to expose playChunk
• ESP32-A2DP
• IRRemote

cd Arduino/libraries && git clone -b expose-play-chunk https//github.com/paulgreg/ESP32_VS1053_Stream_raw.git)

Flash

Flash using « ESP32 DEV Module » (or ESP32-WROOM-DA for my model)

⚠️ You’ll need to change layout to have enougth flash size : NO OTA (2 MB APP/2 MB SPIFFS)
