A WEB server on the Microcontroller with MicroPython

Introduction

In the 2019 AFNOG course we have seen how to connect to sensors and actuators through Cayenne and MQTT. This works fine if the amount of data to be passed over the Internet is small. If however we want to transfer a bigger amount of data, e.g. an image stream from a WebCam, then this solution is not viable. In this case, running a WEB server on the microcontroller is the better solution.

In the following pages we will install a WEB server on an ESP32 running MicroPython.

Several WEB servers are available for MicroPython:

• picoweb with nice tutorials on how to use it: Tutorial 1, Tutorial 2
• MicroWebSrv2

how to make a WebCam work on ESP32 MicroPython

The most powerful and evolved Web server available under MicroPython is probably MicroWebSrv2. Here are step by step instructions to bring up MicroWebSrv2 on an ESP32.
