I have a small web app for which the back-end is a Flask+SocketIO server. I would like to get some data from an ESP8266 into my app. The most simple way to achieve this I could think of was to have the micro controller connected directly to the back-end.
I am using the timum-viw library with this example code to implement the client on the micro controller.
The problem is that on trying to run the example I get

Answered 2018-Jan-09 at 00:21You are mixing two different concepts: In Java, you use the rather low-level Unix sockets and on the ESP you use WebSocket, which are closely related to HTTP. Get a proper WebSocket client library for Java. – Codo Jan 4 at 17:33
