I want to connect to the wifi network opened from esp32 via c# program and view the data sent from esp32. I was doing this project before using arduino via serialport, but I need to do it with local wifi network and I couldn't find the necessary codes to connect to wifi network. Can you help me.
I made a small program using the BMP180 sensor. I show data in C# by transferring data via Arduino and C# program. In this program, I want to transfer data by using ESP32 and connecting to the wifi network (The ones shown in the picture are a program I made over serialport using arduino.
