| Supported Targets | ESP32 | ESP32-C2 | ESP32-C3 | ESP32-C6 | ESP32-H2 | ESP32-S2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | -------- | -------- | -------- | # HTTP Request Example (See the README.md file in the upper level 'examples' directory for more information about examples.) Uses a POSIX socket to make a very simple HTTP request. ## How to use example Before project configuration and build, be sure to set the correct chip target using `idf.py set-target `. ### 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](../../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. ## Example Output ``` I (10557) example_connect: - IPv4 address: 192.168.194.219 I (10557) example_connect: - IPv6 address: fe80:0000:0000:0000:266f:28ff:fe80:2c74, type: ESP_IP6_ADDR_IS_LINK_LOCAL W (10577) wifi:idx:0 (ifx:0, ee:6d:19:60:f6:0e), tid:0, ssn:3, winSize:64 I (10587) example: DNS lookup succeeded.
