Thank you for your reply.
Yes, that’s an option, but I have to develop a PC-based app, and so I would prefer, if possible, not to write any embedded software.
In any case, after writing my embedded app that somehow sends and receives voice files using ADL audio services, I have to interface it from my PC-based app, and the problem of sending/receiving files from the PC to my embedded app is still there.
In short: can it be done using AT commands and the DM port?
Kind regards,
Ernesto
