Problem – Not Working with ESP32 Board 

Solution –

Hi all
I found what is issue with ESP32 and DF Player. When working with ESP32 WiFi/Bluetooth MCU under Arduino SDK for ESP32, you will notice that Serial work just fine. But Serial1 and Serial2 do not. ESP32 has 3 hardware UARTs that can be mapped to almost any pin. But, Serial1 and Serial2 will not work. In case of ESP32 this just has to be done in a slightly different way:

When DFPlayer use HW serial you have to replace
  Serial1.begin(9600); 
by

  MySerial.begin(9600, SERIAL_8N1, 16, 17); (with definition “HardwareSerial MySerial(1);” )
