Connection.open() not firing in server application

[Diji19]

kinectron.makeConnection() is working and I get a peer ID , but when I start the function kinectron.startTrackedBodies(drawSkeleton) the callback won't start.

Yes this is a known issue in Chrome with Peerjs. Peerjs is not firing connection.open on the application side when it receives a peer connection. This is preventing the peer connection from ever sending data between app and client. I am working on resolving this, but in the meantime it seems to not be an issue in Firefox. Please use Firefox for your client side for now.

I tried it know in Firefox, but it seems I have the same probleme in there!

Please post any errors you are getting in the browser JS console.

My code is from Getting Started: API

Many of these are warning and shouldn't be keeping the code from running. Can you send a screenshot so I can see what is actually an error (red) versus a warning (yellow). Some of these are in German I think so I'm not sure what they are.

Are you working in the p5 online editor or from your local host?

Are there any errors in the server application console?

I am working from my localhost and I have no errors!

[lisajamhoury]

Can you post your code? Are you getting errors on the server application (the electron application)?

`// Create a p5 canvas (learn more at p5js.org) var myCanvas = null;

// Declare kinectron var kinectron = null;

function setup() { // Create a p5 canvas myCanvas = createCanvas(500, 500);

// Set background color background(0);

// Initialize Kinectron initKinectron(); }

function initKinectron() {

// Define and create an instance of kinectron kinectron = new Kinectron("10.18.250.25");

// Connect with server over peer kinectron.makeConnection();

// Request all tracked bodies and pass data to your callback kinectron.startTrackedBodies(drawSkeleton); }

// The incoming "body" argument holds the Kinect skeleton data function drawSkeleton(body) {

// Clear the background background(0, 20);

// Draw a circle at the location of each joint for(var i = 0; i < body.joints.length; i++) {

// Get the joint
var joint = body.joints[i];

// Set the drawing color
fill(100);

// Map Kinect joint data to canvas size; Draw the circle
ellipse(joint.depthX * myCanvas.width, joint.depthY * myCanvas.height, 15, 15);

} } `

Thanks for posting your code. This appears to be an issue with the peerjs library that is responsible for sending data between the server and the browser. I am working to find a solution and will post here when it's resolved.

Hi @Diji19

I just published a new release of Kinectron server and application. I believe this should fix the problems that you are having.

The new server is available at https://github.com/kinectron/kinectron/releases/tag/0.2.0 and the client is at:

https://cdn.jsdelivr.net/gh/kinectron/kinectron@0.2.0/client/dist/kinectron-client.js

Note that the changes will only work with a local server (like SimpleHTTPServer), not from the p5 online editor, which I hope to have running again in the next few weeks.

Please re-open the issue if it doesn't work for you.
