ESP32 Hands-Free Device Creation
$30-250 USD
Paid on delivery
I need an advanced ESP32 developer to help me connect a 3.5mm headphone with mic to an ESP32 and turn it into a hands-free device for calls. I have a full working example at the provided Github link. However, this example expects an external DAC or codec. I want to use the internal DAC and ADC and connect to a TRRS adapter. Your guidance and code will be crucial for this project.
