* 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.
## Example Output

By default, the `ws://echo.websocket.events` endpoint is used. You can setup a Python websocket echo server locally and try the `ws://<your-ip>:5000` endpoint. To do this, install Flask-sock Python package
```
pip install flask-sock
```
and start a Flask websocket echo server locally by executing the following Python code:
```python
from flask import Flask
from flask_sock import Sock
app = Flask(__name__)
sock = Sock(app)
@sock.route('/')
def echo(ws):
while True:
data = ws.receive()
ws.send(data)
if __name__ == '__main__':
# To run your Flask + WebSocket server in production you can use Gunicorn:
