Invalid CMD value

DFPlayer-Mini-mp3/DFPlayer_Mini_Mp3/DFPlayer_Mini_Mp3.cpp

Line 403 in c0bc055

mp3_send_cmd (0x18);

I spent quite a bit of time finding the error. I hope someone sees this message and doesn’t follow my path.
There may be a mistake in your CMD source. The correct value for random playback is the command (0x08, 3)

Fragment from the documentation:
0x08 | Specify playback mode (0/1/2/3) | Repeat/folder repeat/single repeat/ random
