DFR0768 questions to exactly detect the End of mp3 file
MassimoBesozzi 2022-09-26 00:31:31 833 Views2 Replies hi,
as I am finishing my project with the DFPlayer Pro, 128MB of memory, I would like to know if there is a safe way to know the end of an mp3 file.
I currently use Query AT + QUERY = 4 \ r \ n to know the total time of the file.
But it is not very accurate, so I would like to know if there is a better method or if you plan to implement one
Also it would be very useful for me to be able to instantly stop an mp3 file to run a new one. This is currently not possible
I use the command AT + PLAYFILE = / path / file.mp3 \ r \ n
Should I use the AT + DEL \ r \ n command, or does this erase the file from memory?
Thanks for the kindness
Best regards

Hi!
You can only use code to determine the duration of a file.
You can consider using AT+PLAY=PP, AT+PLAY=NEXT or AT+PLAYMODE=2.
jenna thank you for your reply.
The problem is that I need to stop an mp3 while it is still running and immediately start another mp3.This is a priority for me because I would like to use the DFPlayer Pro in a pinball game where the sounds must follow the game in real time.I tried some DFPlayer Pro modules and, after a certain number of times of playing an mp3 without the previous one finishing, the modules stopped working. They are no longer even recognized by the PC.It is not a cable problem because by connecting a new DFPlayer Pro to the PC, it is immediately recognized
Thank you for any help
