I’ve got the DFPlayer with the GD3200B instead of the better YX5200, but it works.
As part of my game, so MQTT controlled.
Code
I’m using Soft Serial
// based on code from:
// https://github.com/Makuna/DFMiniMp3/blob/master/examples/PlayMp3/PlayMp3.ino
// above example has no wifi/mqtt and is missing the SoftSerial include line

#define wifi_ssid "SSID"
#define wifi_password "SSIDPASS"
