• Hi,

    I got my Puck.JS today and wanted to get right into programming without waiting for my bluetooth dongle to arrive. So I tried to use the relay function.

    Unfortunately I could not get it to work though. It always stopped with the message "Starting Websocket connection" on the phone. I tried it with my Nexus 5X on Android 7.1.1 and Chrome 57.0.2987.132.

    I then tried to start up the server on my own computer to potentially see what went wrong node server.js did not server anything under /relay and I also read that it only supports one session at a time, which would probably cause problems with the relaying anyways.

    With the python server twisted I managed to server the root directory with ssl including the /relay subdirectory using twistd -no web --https=4444 --path=.. But I could not figure out if there is a websocket relay server included or if there is a default one that I should be running.

    I also tried setting var WS_HOST = 'wss://espruino.com:8443'; with the UI hosted from my computer. With that and the following code added to relay.js, I got the output Encountered an error: {"isTrusted": true}. Which didn't yield any additional insights and might just be due to Cross-Origin restrictions.

    socket.addEventListener('error', function (error) {
      term("Encountered an error: "+JSON.stringify(error));
    });
    

    Any pointers on how to properly run a local setup or maybe get the relay on espruino.com working are much appreciated.

    On a related note: @Gordon Did you try or think about using peer-to-peer communication using WebRTC instead of websockets for the communication between the browsers? That way there might not be a need for a websocket server.
