I have the following problem that I'm struggling with.
I use an ESP-WROVER-KIT 4.1 in vscode and esp-idf.
As a test, I created 2 tasks with FreeRTOS. One of them should control my DFPlayerMini module.
For this I use this library -> https://github.com/nopnop2002/esp-idf-DFPlayerMini.
The module is connected to GPIO19 (TXD0) and GPIO25 (RXD0).
The serial baud rate is set to 115200 (even though I know that the player needs 9600) but when I set the baud rate to 9600 all I get is gibberish about the terminal and in the example as far as I can see the baud rate is not that important either placed. The output otherwise looks good and the serial communication seems to be working, at least basically... but I can't get a file to play.
The SD card is formatted correctly and previously worked in arduino and platformIO.
The player is initialized and also outputs status messages.

I hope someone can help me, I would be happy to provide more information.
best regards Alex
I managed get some files played but it still don't work well.. but it tells me the baudrate is ok.. i think the error is coming up because the commands are to frequent fo the player.. so i will try to impliment a function that waits until the player is finished .. its all very testing .. to be able a stable use of the device and it is not my final purpose for it..
