Using ESP32 and DFPlayer Pro failing
Nicolas.Berger 2023-10-23 21:52:15 535 Views3 Replies Hi,
I am not able to use the DFPlayer Pro with my ESP32 (NodeMCU 32S). It seems that it can connect, but I can't do anything with it. Sound works without ESP, it even works as speaker over USB. So, hardware seems ok.
Running the provided sample code, I get this output. I think the AT commands don't make any sense (I have only 3 files stored on it). I can't play any files, nor change any setting.
VOL:0
PlayMode:6

File number:13472
The number of files available to play:13472
The time length the current song has played:13472
The total length of the currently-playing song: 13472
The name of the currently-playing file: 牥潲r
Do you have any idea where it fails? Is there a way to troubleshoot?
Thanks for helping me.
So I looked further and if you change 2 and 3 to 1 and 3 when using an ESP32 you have to use the RX and TX pins and it will communicate and give the correct values. My new issue is I can't use serial print afterwards which isn't too big of a deal if it wasn't my primary way to debug things. But To correct it, rx into tx and tx into rx and pin 1 is tx in code and pin 3 is rx within the code. Do not use pin 4 or pin 2 from my experience…
Antoine.Washington Has anyone figured this out? I'm running into the same issue.
