Hi @mathieucarbou , can you please add an example of a WebSocket client?

Hi,
there is no websocket client: this lib is a server (and websocket server).

if you want a client, you can use websocat CLI tool.

@mathieucarbou So the AsyncWebSocketClient class does not relate to the client itself?

[mathieucarbou]

No: it represents a browser connection to the websocket server.

@mathieucarbou Maybe this is suitable if I need to connect from one ESP32 to another ESP32 (WSS Server)?

I think I'm confused on this also. (in fact, I'm sure of it....)
I don't want anybody to write code for me (although I'd never refuse any help)

But I'm not sure where to go from here. I went from ESP-NOW, to "http-GET" to websockets, to bluetooth, now I'm back to maybe http-GET and/or websockets again.

I have a central unit that "should" mainly display a lot of data (temperature and tank levels for an RV). I have LVGL running on that just fine. But I have about 7 other ESP32's out there monitoring tank levels and things like temperature. The data from each would be small.

But I'm confused about how to communicate everything. I need to send a "request for data" to each remote unit (to control data flow and prevent crashes). The remote would respond with a simple data packet (level, temp sensors) and then the main would respond back with a checksun to ensure data wasn't lost. Simple....

But one device (Shelly power monitor) requires http-GET (or websockets, but I haven't got that to work)
So, since HTTP blows ESP-NOW out of the water, I can't use that as planned. I spent a lot of time on BLE, but I found out I can't handle the number of clients. So I'm back to http and/or websockets.

Can I use regular http "get" to send/receive the way I need? If I have to have websockets, how does that work?

I've done a lot of programming, but nothing with http or even much communications, just a bare metal unit, self/contained etc....

I know it'll work, I'm just worn out and confused. Everything looks one directional, but says bi-directional.

Anything would be a great help, I've blown so much time on everything else, only to find out it won't work.
