Cloud providers like OpenAI Realtime and Gemini Live ship one speech-to-speech model. OpenToys gets the same experience locally by chaining three models on your Mac.

Connection flow

1

Toy boots

The ESP32 starts an open access point called ELATO at 192.168.4.1. The LED glows pink while it waits.
2

Mac joins and handshake

The toy probes ports 49320 and 8000 on your Mac until the OpenToys server answers, then opens a websocket. The LED turns white.
3

Conversation

Mic audio streams up, synthesized speech streams back. Press End in the app to close the session and view the transcript.

​
Troubleshooting

  • ELATO isn’t listed: the toy isn’t powered or the firmware didn’t flash. Reflash and watch for the pink LED.
  • Joined but nothing happens: make sure OpenToys is running on the Mac.
  • Play is greyed out: wait for the status row to read Ready on device.
