# 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
|
|
|
|
* Open the project configuration menu (`idf.py menuconfig`)
|
|
* Configure Wi-Fi or Ethernet under "Example Connection Configuration" menu. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
|
|
* Configure the websocket endpoint URI under "Example Configuration", if "WEBSOCKET_URI_FROM_STDIN" is selected then the example application will connect to the URI it reads from stdin (used for testing)
|
|
|
|
### 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
|
|
```
|
|
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
|
|
|
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
