In this tutorial we will check how to connect the ESP32 to a HTTP/2 server, using the Arduino core.

We will make use of the sh2lib IDF wrapper, installed as an Arduino library. For a video explanation on how to get this wrapper to work on the Arduino core, please check here:

Tested on ESP32 FireBeetle board:

Original IDF HTTP/2 request example:
github.com/espressif/esp-idf/blob/master/examples/protocols/http2_request/main/http2_request_example_main.c

Test server:
http2.golang.org
