Which framework should be used to send and receive audio data from a custom device?


i have device, more headset mic. framework apt receive audio device in app , send audio?
had reached conclusion on external accessory framework in further research found similiar functionality in multipeer connectivity framework. in case can skip mfi certification process. more apt purpose?


follow question: there way around mfi certification using external accessory framework?
 

at least 4 possible wired solutions:
  • mfi enrollment , certification of custom device
  • convert devices io to/from analog audio, , use lightning headset adapter
  • camera connection kit + having device imitate usb audio device class profile
  • camera connection kit + usb ethernet adapter + raspberry pi (or equivalent) + digital io pins (or usb, etc.) connect device
you connect raspberry pi via wifi, , talk device through pi's io pins way.
