6 years ago If you run netcat on 127.0.0.1 port 9001 (nc -l 9001) first, then run odas live, that should work.
Hope this helps

Hi, Thanks for developing this nice tool. I really appreciate it.
What I want to achieve is sending SSL(sound source localization) information to other machine using respeaker 4 mic array with raspberry pi.
So, my basic understanding is ODAS can send JSON data through websocket. isn't that right?
But I keep seeing this message

6 years ago @taospartan Thanks! Now it seems working. But from other machine, how can I get this JSON data? Any instruction or tutorial for this? I tried to read through Websocket (https://developer.mozilla.org/en-US/docs/Web/API/WebSocket), but it didn't work out.

6 years ago You could use node.js there are plenty of socket tutorials for this, or play around with python again lots of examples for this. Just depends on what your overall aim is and what language you are comfortable in.
In the odas config just change 127.0.0.1 to which IP address you want to send the json to.
