WiFi Connection between two ESP-controllers
Two different approaches to achive connection between two ESP-controllers. One controller is the client, the other is the server.
In the first approach the client makes a request, acknowledged by the server which establishes the connection. Information is excanged and the connection closes immedately.
In the second approach the client's request is acknowleded with a premanent connection by the server where both the client and server exchange information contiuously. The connection closes when the client issues a 'stop' command.
Some issues are detected using different WiFi routers. This can be avoided using the same router for the both connecting devices.
Look into the github repositories for the sketch code:
