[PICO-W] Are sockets working?

[ollielindsey]

I'm currently trying to get a simple socket client connecting to a server on the network, working from the latest commit (c7c4054) on the pico-w branch, but the Cyw43 device doesn't appear to have a fd or socket generated for it.

Just checking whether I'm doing it wrong or whether it's an issue/forthcoming feature (I appreciate you're working towards supporting the pico-w still and it's very much appreciated).

I've tried several variations with net.createConnection, net.connect and now the below.

I'm just using the basic code below once Wifi has been established. Connect callback is never called and connection never seems to happen:

wifi.connect(
    {
        ssid: '<removed>',
        password: '<removed>',
        enforce: true
    },
    (err, connection) => {
        if (err) {

            console.log('error');

        } else {

            console.log('connected');

            console.log(connection);

            clearInterval(timeId);

            timeId = setInterval(function () {
                if (pico_wifi.getGpio(0) == false) {
                    pico_wifi.putGpio(0, true);

                } else {
                    pico_wifi.putGpio(0, false);
                }
            }, 1000);

            var conn = { host: '172.16.0.71', port: 8080 }; 

            //Create the socket client.
            const clientSocket = new net.Socket();

            //Connect to the server on the configured port 
            clientSocket.connect(conn, function(){

                //Log when the connection is established
                console.log('Client : Connected to Server');
                
                //Try to send data to the server 
                clientSocket.write('Hi from the Client');

            });

            var clientNet = net.createConnection(conn, () => {
                // 'connect' listener.
                console.log('connected to server!');
                clientNet.write('hello, world!\r\n');
              });
              clientNet.on('data', (data) => {
                console.log(data);
                clientNet.end();
              });
              clientNet.on('end', () => {
                console.log('disconnected from server');
              });

        }
    }
);

I just implemented WIFI driver for pico-w Cyw43 module. the next step is implementing network driver for pico-w Cyw43 module.
The bottom line is current FW does not support network socket because network driver for pico-w Cyw43 module.
Please try it once I finish to implement network driver for pico-w.

Do you have any update about this?

@LuisGerar321 pico-w-1.1.0-beta.4 support PICO-W CYW43 module. TCP socket and HTTP protocol is working now. Please try it with the latest beta 4 release.

What's the plan for UDP side? Lots of things use it, such as nice protocol from ESP32 for setting SSID/password, as well as syslogging. I dont mind helping. The dgram is pretty well documented, its a matter of CYW43 support for it, but would think udp should be easier.

Hello @communix, if it's possible to implement WebSockets connection?
