title: Send data from one Wemos to another
body: <p>I have 2 Wemos d1(retired) boards. I just simply need to send some data or a letter from one to the other. I searched the web deeply and found some complicated NodeMCU stuff and so on. Even though I could send data when I flashed NodeMCU to my Wemos, it was useless because my project is about arduino. I need to work with Arduino IDE. There is also a way to create a WebServer on one of the wemos and then deal with html files. But isn't it so complicated for just sending a couple of bytes? I don't need any webserver or html page. So please help me.</p>
