Is there a way to poll the MP3 player to see if it is currently playing a song?

Thanks,

hi.Shannon

Can you try command"7E 02 C6 7E",it will return "0XC6 XX YY ",XX is High byte of the file number and YY is Low byte of the file number.

Yeah, I found this data sheet for the chip very helpful:
microelectronicos.com/datasheets/WT5001.pdf

I ended up using the command “7E 02 C2 7E”. After C2 it returns 1 if it is playing, 2 if it is stopped, and 3 if it is paused.
