Esp32 play sounds to a speaker over bluetooth

I have an esp32 dev board (esp32-Wroom-32e? Processor I think). I want to be able to pair it with a generic bluetooth speaker and send sounds/music to it. I have been unable to find any examples of that. Is it doable? How can I get started??

Hi,
You will find it at the
esp-adf project on GitHub. The ADF is the audio framework and contains several applications
examples related to audio, including Bluetooth players.

Please forgive my ignorance. This is my first experience with any microcontroller. I have been a computer programmer for mainframe/mini/PC systems for over 40 years, but this is new to me. Can this code me 'integrated' with a normal Arduino-IDE sketch or would I have to start all over in C ?

Thanks. I will post on the arduino forums and see if there is something equivalent there. Don’t really want to rewrite everything for a one off project like this. Have a great day

Hope your journey is great, but know that you are jumping in the pool a bit on deep end with a first project like this.
You should get more familiar with the platform first, and FreeRTOS as this a dual core processor. make friends with menuconfig. There are a bazillion options in there which you can thing of it as your BIOS for a PC. Not having a feature enabled in there will cause some things not to work, so be aware.

Try to resist starting off with Arduino-IDE, and use ESP-IDF. Arduino is a total joke, and will cause more harm than good later in like. ESP-IDF unlocks everything.

Thanks! I probably should have started with the esp-idf but not sure I want to change at this point. Have the project 75% completed already. It’s not a product, just a one off learning project. If I can’t get the mp3 working through arduino, I will switch.
At least the hardware I have built won’t need changing if I switch dev tools
