DFPlayer Pro v1.0 no COM port
slappin.steve 2024-06-10 20:55:31 426 Views3 Replies I want to disable the “MUSIC” prompt when the DFPlayer Pro starts. I dont plan on using it with a board, so as i understand it sending AT+PROMPT=OFF is of no use as this has to be sent every time it starts in order to work.
So, im trying to following the instructions here
https://www.dfrobot.com/forum/topic/315182
using the serial debugging software to disable it there and here is where i get stuck, i need to specify the COM port of the DFPlayer when its plugged into my PC, but when i plug the DFPlayer Pro into my PC is shows up as a mass storage device and it is not listed under Ports (COM & LPT).
I just really want to get rid of this thing saying “MUSIC” when i turn it on, please.
To resolve the "MUSIC" prompt issue on your DFPlayer Pro, you might find this useful reference: try using a USB-to-TTL converter to access the COM port functionality. This way, you can send the required AT command to disable the prompt, even without using a board.
ConnorLigar to anyone who may find this having the same issue as i did. I ended up using software serial through my Arduino Nano.
my previous attempts to use software serial through a sketch on my Arduino Nano to disable the voice prompt failed, but i think it was my code, because i just copied the sample code from the “Sample Code - Play” at
https://wiki.dfrobot.com/DFPlayer_PRO_SKU_DFR0768
i made sure the rx and tx pins were specified correctly in the arguments and then uncommented the line
DF1201S.setPrompt(false);
and on my next boot it did not play “MUSIC”. This setting is persistent, even when using the DFPlayer Pro on its own, not connected to the Ardiuno Nano.
slappin.steve Update:
I bought a SH-U09C USB to TTL serial adapter, which i tested and is functioning. I connected the DF Player Pro to the USB to TTL adapter and I am unable to get any connection to the DF Player Pro. whether i use Arduino IDE, Putty or Tera Term I get no connection.
I thought this forum is where we are suppose to get product support, am i wrong?
