Receving datastring form Matlab
Posted: Fri May 21, 2021 6:51 amHi,
I am new to ESP8266 and have a problem i cant solve.
I want to set up a TCP/IP connection with Matlab do send and receive data.
I set already did set up the ESP8266 as a AP and can connect my PC to it. I also can Ping it from the Terminal.
Matlab sends data as bytes and i already set up the connection to the esp8266, but dont know if it works.
The Problem is i dont want to set up a Webserver so i dont send any POST or GET request and i dont use http protocol.
As far as im now i dont get the data send from Matlab. Can somebody tell me if its even possible to use the ESP8266 in the form i want to and maybe somebody knows what im missing.
Thank you.
