Auto play when the app connect to the Bluetooth

hello I am using arduino mega 2560 - bluetooth HC-05 - android galaxy s8 note

and all I want to do is when the bluetooth connect to the app the app play the audio just .

I search in the internet so hard and I did’t find anything to start with T.T

please help !!!

Although Blynk has a Music Player widget, it’s simply an interface to allow you to send commands to a device (in this case the Arduino). The Arduino then needs to be able to take these commands and use them yo play music that is accessible to the Arduino. Obviously some additional hardware would be needed at the Arduino end, as it has no audio capabilities without this.
