i saw this thread of yours About playing .wav file to gsm and that's exacly my project, but there are not much details there…
i was also confused as if really your dac output from your esp32 really went to the MIC- and not the MIC+?
This will really be a big break-through for me as it's a part of an enterprise application as well as a academic work simultaneously… So i’ll really appreciate all the expertise, experiance, guidance and any type of help i can get…
Thanks a lot
