DFPlayer Pro Slave Mode
Elena.Elena 2023-10-06 14:00:31 210 Views1 Replies Hi,
A simple question about the DFPlayer Pro.
I have connected DFPlayer pro to PC and initially contained with one mp3 file, which was working fine when pushing the “play” button
and listening to the audio,
but suddenly it changes to Slave Mode.
Could anyone tell me how to exit Slave Mode? Since it was alright before.
By the way we are not using arduino or any platform, simply connect the DFPlayer pro to the PC.
Thanks a lot!
Hi,
This MP3 player module supports four controlling modes: Arduino, AT command, on-board buttons, and ADKEY.
I'm not sure about the specific situation you faced.
I suggest trying to connect the module to a PC with a USB cable and save audio files into the module storage again.
If still not working please provide more details.
