HTTP interface needed for ESP32 (not a web server)

Q&A Forum › Category: ESP32 › HTTP interface needed for ESP32 (not a web server)

Bernie asked 2 years ago

Hi — I am using ESPAsyncWebServer at the moment, but it is limited, for example it cannot act as a serial monitor.

I would like my app to occasionally send data to a connected web browser, without the browser doing a GET or POST. This may block while transmitting the data. The data to be displayed.

Also I would like to occasionally read the HTTP input channel and see if there are requests pending. Reading should not block if there is no input.

I have used the WebSerial package by ESPAsyncWebServer, and it is of little use. It limits your screen to a 80×24 terminal, has no scrolling capability, etc.

Can you please lead me to such a library either at RNT or elsewhere?
Any response is greatly appreciated.
Thanks

Hi.
Did you check our tutorials about GET and POST?
https://randomnerdtutorials.com/esp32-http-get-post-arduino/

I think the examples provided in the ESP32 arduino core might also be useful:

I hope this helps.

Sara
