What

The idea is to experiment a bit more with ESP now, in particular in combination with audio transfer.

Stuff to learn:

Possible end result: A kind of zero-standby power intercom. When you press the button, an ESP8266 is powered up. It immediately starts transmitting audio from a digital I2S microphone over ESP now. The receiving end will probably be an ESP32, that receives the ESP now audio and converts into a standardized audio-over-ip protocol, e.g. VBAN.

Plans:

  • build an Arduino playground project so I can access the API from the command line and play with it
  • start with an ESP32 + INMP441
