Hello,The code is nonsense. It won't compile and i don't see how it even would compile.
Doesn't work. "No radio available"
You need this library installed: https://github.com/DFRobot/DFRobotDFPlayerMiniIf it still doesn't work try selecting "atmega 328p old bootloader" in the IDE device section.
Thank you! It works perfectly. I'm making a wireless door sensor that when the door opens a female voice says door open.You forgot to tell people to install this library, without it the code won't compile:https://github.com/DFRobot/DFRobotDFPlayerMini
