Description
Hi, I'm using esp32 and the example in examples/esp32/WebSocketClient/WebSocketClient.ino
With a node js server and socket.io
It keeps connecting and disconnecting I don't know what I'm doing wrong

//WiFi.disconnect();

}
// server address, port and URL
webSocket.beginSocketIO("192.168.150.243", 3000);
// event handler
webSocket.onEvent(webSocketEvent);
// try ever 5000 again if connection has failed
webSocket.setReconnectInterval(5000);
}
void loop() {
webSocket.loop();
}
Node.js server:
const app = require( 'express' )();
const http = require( 'http' ).createServer( app );
const io = require( 'socket.io' )( http );
io.on( 'connection', ( socket ) => {
console.log( 'connection' );
socket.on( 'disconnect', () => {
console.log( 'disconnect' );
} );
} );
http.listen( 3000, () => {
console.log( 'Listening on port 3000.' );
} );
If I begin the webSocket with begin or beginSSL it just keeps printing [WSc] Disconnected! on the console.
When I try with webSocket.beginSocketIO("192.168.150.243", 3000); then it connects but keeps disconnecting and shows this
[SETUP] BOOT WAIT 4...
[SETUP] BOOT WAIT 3...
[SETUP] BOOT WAIT 2...
[SETUP] BOOT WAIT 1...
[WSc] Connected to url: /socket.io/?EIO=3
[WSc] Disconnected!
[WSc] Connected to url: /socket.io/?EIO=3
[WSc] Disconnected!
[WSc] Connected to url: /socket.io/?EIO=3
[WSc] Disconnected!
[WSc] Connected to url: /socket.io/?EIO=3
[WSc] Disconnected!
[WSc] Connected to url: /socket.io/?EIO=3
[WSc] Disconnected!
the logs on the server show this, only with beginSocketIO
