In this statement, we print the IP address using the ifconfig() method on the sta_if object which we created previously. Advantages: Flexible and extensible. The main part of our MicroPython script starts with defining a web_page(). The SOCK_STREAM is used for end-to-end communication between two points using connection-oriented protocols. Home Tutorials Micropython and ESP32 blink an led. You are seeing this error either because your ESP is not connected to internet or because RAM is full. But, in the case of ESP32 and ESP8266, we will have to disable debug output manually by adding the following lines to the MicroPython code of our project. Therefore, we will turn off the onboard LED of ESP32 or ESP8266 and also update the status of the LED indication variable to OFF. It also provides the address of the client (addr). Required hardware : ESP32 development kit, Led, DHT 22 sensor, Required software: Micropython firmware, pycraft IDE, What is picoweb :  It is a “micro” web micro-framework (thus, “pico-framework”) for radically unbloated web applications using radically unbloated Python implementation, MicroPython, Features: Asynchronous from the start, Small memory usage, API affinity for similar web frameworks like flask, From REPL prompt of micropython, install picoweb, upip.install(‘picoweb’) With this IP address, web clients can access the Web server through an existing local network. As an example we’ll build a web server with ON and OFF buttons to control the on-board LED of the ESP32/ESP8266. For example, in this microPython based web server, the body part includes icons, heading, and buttons. Besides this when a user clicks the LED ON button, you will be redirected to /?led_2_on URL. when a user clicks the LED OFF button, you will be redirected to /?led_2_off URL.
