README.md

Websocket Sample application

(See the README.md file in the upper level 'examples' directory for more information about examples.) This example will shows how to set up and communicate over a websocket.

How to Use Example

Hardware Required

This example can be executed on any ESP32 board, the only required interface is WiFi and connection to internet or a local server.

Configure the project

make menuconfig

  • Set serial port under Serial Flasher Options.

  • Set ssid and password for the board to connect to AP.

Build and Flash

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

make -j4 flash monitor

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

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