Here is a minimal example where in addition to setting the ESP32 up as an access point a TCP server is also started on port 80. socket host quot 192. 11b g n Wi Fi BT SoC moduleLow power 32 bit CPU can also serve the application processor Up to 160MHz clock speed summary In this post we are going to create a webserver using ESP32. begin ssid password while WiFi. So you need to have Arduino IDE installed as well as the ESP32 add on. 96 OLED display. This web page is accessible through IP address which is assigned to ESP32 by a WiFi network. h library. h quot include quot esp_camera. The WiFi and TCP IP libraries requires a lot of space so you will not be able to use the no FLASH mode On the sample page Select the HTTP Server IoT SDK On the debug method page specify the debug settings that worked with the ESP8266 OpenOCD tutorial Press Finish to build the project. We create an instance of WiFiClientSecure import socket sock socket. h library which will expose a class that we will instantiate in order to configure the server routes and functionalities. esp32 wifi server example
