Supported Targets ESP32 ESP32-C2 ESP32-C3 ESP32-S2 ESP32-S3

HTTP server with TLS support using mbedTLS

(See the README.md file in the upper level 'examples' directory for more information about examples.)

Simple HTTPS example that uses mbedTLS to establish a secure socket connection using the certificate bundle with two custom certificates added for verification:

How to use example

Hardware Required

  • A development board with ESP32/ESP32-S2/ESP32-C3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
  • A USB cable for power supply and programming

Configure the project

idf.py menuconfig
  • Open the project configuration menu (idf.py menuconfig) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in examples/protocols/README.md for more details.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
