Hello. I just purchased the espluxe after finding it here.
I have NOT flashed home assistant. Just using default firmware flashed onto the device. I have a 16GB microSd card. Formatted it to fat and put an mp3 on it. Now I put it in the device and hit play but nothing happens except for a human voice that says “beep”
The base “bluetooth” app should do I have not tested this function for a while. and i know it is picky on the format of the mp3, you can plug the serial log and check error message.
Otherwise the Arduino library has example for the Luxe for things pretty close but you will need chatgpt to make an example
Chatgpt will probably write you the app in a minute providing the example above.
