> I am using an adafruit-nrf52-pro-feather (nrf52832) to run my project of detecting voice by this below scenario:
> ++ Setting up:
> [PC] ==== USB cable =====[Adafruit] * * * BLE * * * [Phone]
> + Audio files are very small size (less than 100kB or 20 seconds), with ADPCM format
> [http://www.kowatec.com/prod/ap/products.php?a=adpcm] 
> + USB cable which is delivered together with the board, but currently I am using as UART port for monitoring serial log.
>  
> I still have some concerns for this scenario as:
> 1) For transferring audio files from PC to the Adafruit, what are the available approaches ?
> Is there any way to use the same USB cable and still have UART port debugging normally?
> 2) I suppose it would stay in RAM by default, but is Ada RAM enough for the above size?
> 3) Can I send the file (in RAM) directly via BLE or I need to do somethings else before sending via BLE?
>  
> I appreciate any suggestions/helps or some reference links.
> Best Regards,
> James, Dinh
