I found some websocket server example code that includes this library file "esp_websocket_server.h" but it doesn't find it. I am running IDF v5.0.1. My web searches have not been successful as well. I have working code using the "esp_http_server.h" library but the state of any of the GPIO upon a web page refresh is reset. It is my understanding, that I should be using websocket server code in ordering for states to be updated with the actual state??

esp_websocket is now a component. See https://components.espressif.com/compon ... ket_client . You can run 'idf.py add-dependency "espressif/esp_websocket_client" ' to add it to your project.

Hello ESP_Sprite,
Thank you for your response. I enabled notifications to me email but I did not get notified.
I saw that esp_websocket is a component. My understanding is that the client is not the same as a server.
I'll need to do some more research on this....

Not sure I fully understand what states need to be updated where, but you can check the IDF websocket server example, or consider server-sent events.

Let me look at the websocket server example. Thank you!
