Connect DFPlayer with Cubcell?

#1

Has anyone used the DFPlayer with CubeCell? If I use softSerial I get this error:
no known conversion for argument 1 from ‘softSerial’ to ‘Stream&’
at code:
if (!myDFPlayer.begin(SS)){
Serial.println(F(“Unable to begin:”));
Serial.println(F(“1.Please recheck the connection!”));
Serial.println(F(“2.Please insert the SD card!”));
while(true);
}

I tried to use both the CubeCell boards and with HTCC-AB02 I used Serial1 and Serial2 with no success.
Serial1 .begin(9600);
if (!myDFPlayer.begin(Serial1 )) {
Serial.println(F(“Unable to begin:”));
Serial.println(F(“1.Please recheck the connection!”));
Serial.println(F(“2.Please insert the SD card!”));
while(true);
}
It still does not connect to the DFPlayer
Any ideas what I have done wrong? Thanks.

You can try to add a 1K resistor to the connection between TX and RX, like this:

Thanks for your help! I have it connected with both resistors and it did not connect to the player. I got in a more expensive I2C player and everything works.
