Socket.emit

[vlp-github]

Hi, Really nice lib !! Just a quick question, on my socket.io server or client I use:

• To send: socket.emit('messageType', 'hello');
• To read: socket.on('messageType', function(message){ alerte("hello too");}

In my ESP code, I have used: client.sendJSON("messageType","hello"); but my server doesn't receive my "hello"

any tips ?

Thanks !

Hi,

thanks for using this library.

Did you try running the example provided with the lib? is it working?

I remember my firewall was messing with my experiments back then, maybe you can also check that

Let me know

Thanks for the answer. Yes, my ESP can reach my server. On the Serial port I have all the log that confirm it:

Connexion établie

Connecting via Websocket
Websocket send

Sec-WebSocket-Accept: xcTAOQ88pRoo1GQAtE2Roi8I3ls=

And on my Server side I can confirm it as well because once someone get connected with the server I send a message to the client.

io.sockets.on('connection', function (socket) {

    socket.broadcast.emit('message', 'ESP_live');

And indeed, I can see the message ESP_Live on my client page.

However, one I am connected, I don't know how the ESP can send a message.

In my client page I use: socket.emit('messageType', 'hello');

And if I write: client.sendJSON("message","ON"); in the ESP code, nothing happen on my server... no message are received.

Thanks for your help !
