App Control for the ESP32

[WillyBilly06]

Hi! In case you need to open issue about how to control the ESP32 through BLE, it's controlled through my Android app called BDK Audio and I have posted it so come check it out!

Here's the link to the repo for the app:

You need to install Android Studio then build the app and install it to your phone. And for your information, it only be able to connect my ESP32 BLE code only and not any other devices.

@WillyBilly06 If you are any interested I made a fork of esp-idf and ported cfint's codecs and changes on the v5.4 of esp-idf. https://github.com/FlashForger/esp-idf/tree/v5.4.3-a2dp-sink-codecs. It's seems to work without crashing, but I haven't extensively tested beyond that, ldac and sbc seem to be working.

Tried to do it on v5.5 (you can see a branch in my fork repo) but there I get a runtime crash when trying to use ldac.

@FlashForger Hey so I have updated it to support ESP-IDF 5.5.2 and it is on my other repository in case if you still wanna use this for the old IDF. Also, I have updated the AAC decoder on the new one to be much more lightweight and doesn't use PSRAM at all as FDK decoder is really heavy and ESP32 A2DP only supports AAC-LC anyway so I have changed to libhelix one and use their decoder for the AAC.

The repo should also have the new esp-idf in there. I haven't added to the main code to support ESP32 without PSRAM (It will disable every feature available except the A2DP) but I will try to optimize more for it to be able to run everything on internal ram if possible.

@FlashForger Oh and also if we're using without PSRAM, all the codecs still work
