I have an Arduino uno which communicates via UART with an ESP32 (WROOM-32) board. The ESP32 sends any update coming from the Arduino via POST request to my webserver.
From my webserver, I would like to send data to my ESP32 to update the Arduino UNO actions.
I'm not a specialist about HTTP protocol.
In a first approach, I wanted to make my webserver sends a POST request to my ESP32 which would store, in a variable, the data received.
- First question : Is it possible to send POST request to an ESP32 from a webserver ?
- Second question : Do you have any other idea, how to send data from my webserver to my ESP32 board ?
