Ok, weird thing, the mp3_play_physical command works but the numbering is based on the order the files are copied over onto the SD Card, whereas the mp3_play command just doesn't work...I am getting a strange click from repeating the hum, but it might be he audio file itself, so will modify and test.


The actual lib DFRobot is providing is incomplete, not developper-friendly, and flawd for some functions.
Add to that a datasheet also incomplete and containing some false info, and that will explain your problems.

With my project (which ils close to completion) I'll provide an all new lib for DFPlayer based on SoftwareSerial communication (forget about busy pin ans replace it by TX pin).
