    FAQ

    • How do I turn off the module beep?

      Method for disabling the DFPlayer PRO beep:

      The voice prompt is enabled by default when the module is delivered.

      If it needs to be turned off, please set it in the AT instruction. The specific setting method and software used are as follows:

      1.Download the SERIAL debugging software , you can directly use the software we provide(https://drive.google.com/file/d/1RgP0G4nEWa7h251SPwDiloATDb4KpNVc/view?usp=sharing), and in the main interface to change the language to English mode.

      2.Connect Dfplayer Pro to your computer, open the Port column of Device Manager, and view your Dfplayer's COM number.

      3.Open the serial debugging assistant, select the correct COM port, according to the following figure to set the correct baud rate;


      4.Type AT in the input field and press Enter. You should see the window return "OK", indicating that the AT command has entered setup mode;


      5.To turn off the hardware prompt tone, enter the command "AT+PROMPT=OFF" to turn off the prompt tone and save it after power failure.
      For more AT instructions, see the Wiki interface description (https://wiki.dfrobot.com/DFPlayer_PRO_SKU_DFR0768).
