Hello,
I'm using the audio application provided by nRF. I want my device to play an audio file containing a sound saying "Connected" whenever the board is connected to the audio device (like a mobile phone). Is it possible to store files directly in the flash memory without an SD Card? If yes, can you please provide a reference or source for the same.
If I had to store the file in an external memory, how can I interface an external memory block to the development board?
