I am using Arduino Websocket (https://github.com/Links2004/arduinoWebSockets/blob/master/examples/WebSocketServer/WebSocketServer.ino) and your html connects to my websocket but only scrolling time without chart. I use webSocket.sendBIN(socketNumber, (uint8_t *) bytearray,bytearray.length ); Please help to find correct format and type (binary,text,etc). Thank you
