usocket implementation to detect when a client disconnects

[Hruthik0x]

Someone please show me an implementation of micropython code to setup a socket server that can handle multiple clients simultaneously and can detect when a client connects, disconnects.
There should be a mechanism, to detect which client disconnected.

Hi
Did you look at github.com/peterhinch/micropython-async/blob/master/v3/as_drivers/client_server ?
For me the timeout is good.. you can decrease it..
Hope that help

But for this, I have to keep emitting text for every timeout seconds right ? Isn't that polling ?

I don't know what your expect to do with opening socket.. In this example userver wait for an exchange by uclient and if the timeout exceeded userver close the socket connexion..
Perharps it's your client that have been to run userver?

In my case, I just want the server to know when a user connects and disconnects from the server. Socketio, Flask_socketio have something like @socket.on("connect") and @socket.on ("disconnect") to detect when a client connects and disconnects, they also provide the sid, by using request.sid (unique to each client, could be used to identify each client and send message specific to a client) I am looking for something like that in micropython.

Yes ok it's like websocket..
You will find them under microdot (it's framework web) under micropython as a 'small' flask
but there's not directly this function to know if connect/ disconnect...
Have a look to microdot it's an amazing web server !
You can also type google 'websocket under micropython'☺

Thank you. I'm planning to contribute to micropython, please tell me where to start (I am new to micropython, so I want to know how to write code to contribute, like build a new library etc.)

Me I'm only try to give a good orientation for questions.. when I can... Rarely I will push code ... Read most answer from people on the right list and you will have the answer.. World of micropython is amazing ☺
