Serial Port JSON Server is a websocket server for your serial devices. It compiles to a binary for Windows, Mac, Linux, Raspberry Pi, or BeagleBone Black that lets you communicate with your serial port from a web application. This enables web apps to be written that can communicate with your local serial device such as an Arduino, CNC controller, or any device that communicates over the serial port.

No 'Access-Control-Allow-Origin' header from localhost to localhost #53

Closed binaryangel-noa closed 6 years ago

binaryangel-noa commented 6 years ago

Hallo,

i am calling the server on localhost and get the following response: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access

And websocket returns always 404.

That sounds to me like you're not connecting to a websocket, rather you're trying to do an HTTP ajax call?
