M35 send/receive voice through UART


Is there an option to send and/or receive voice as data packets through the UART interface (COM-port)?

For instance, if audio is not supported what is the command AT+QSFR (Preference Speech Coding) then for?

Thanks in advance!

Yes, but I don’t know whether you want the function of recording or the function of storing audio files. You can refer to the documents I sent you. One document is about recording and broadcasting, and the other document is about transferring MP4 files
