Getting Started with C# NanoFramework: WIFI Scanning, Connecting, and HttpWebRequest on ESP32

Congratulations! The new board has finally arrived, without further ado, let’s get started.

The main function of the ESP32 is WIFI. With WIFI, it can directly connect to the home WIFI router and access the internet. At this point, it acts like a small computer or smartphone, making it very convenient to connect to the internet.

The ESP32 WIFI has three main modes:

1. AP mode (WIFI router mode), where it becomes a router itself, providing WIFI services to other devices.
2. STA mode

How to Fix WiFi Connection Issues on Google Phones/Nexus/LineageOS

Have you ever noticed that after flashing foreign Android native systems, when connecting to all WiFi networks, it prompts "Connected, but no internet access"? This message appears, but you can still browse the internet normally. This is actually because the server used internally by the system to verify network connectivity is unreachable from China, hence the system prompts that there is no internet connection. So how can we solve this

Remote Control LED Lights with Arduino UNO R4 WiFi

Arduino UNO R4 WiFi (hereinafter referred to as UNO R4 WiFi) has updated its WiFi functionality, using the ESP32-S3 WiFi module for this upgrade. This module, launched by Espressif Systems, is a WiFi and Bluetooth module that enables remote control and monitoring of devices and data exchange with other devices.

Next, let's implement the updated WiFi functionality!

By establishing an AP, we can remotely control the UNO R4 WiFi LED switch.
