PLEASE NOTE:- I'm working with ESP32 for the first time, I have 3-4 months experience with Arduino
I was trying to play an mp3 audio using ESP32 and DFPlayerMini but every time it shows these two errors:-
Unable to begin:
[login to view URL] recheck the connection!
[login to view URL] insert the SD card!
Link for the code is available at GITHUB
I know only these things about it-
The SD card is inserted and working perfectly with ARDUINO UNO.
The Rx and Tx is causing the problem (I'm using p16 and p17 as Rx and Tx respectively) also, I tried interchanging the Rx and Tx but no luck.
I don't know what is the model of the board as I purchased it from a local store but I know this (I could understand these only) -
ESP WROOM 32
ESP Dev Module (I uploaded the code with this and the code was uploaded)
The Pins are not like shown in the pinouts available online; For eg - I got to know that P16 and P17 are the Rx2 and Tx2
Please help me with this supposing me to be a dumb newbie :)
