WiFi Support for ESP32 / ESP32-S2

[urish]

WiFi support will allow you to connect to various hosts on the internet using standard protocols and standards: MQTT, REST, WebSockets, etc.

Using MQTT with libraries like PubSubClient.h would be great. It would allow the development of complete projects with digital twins of embedded systems, a significant advance in the democratization of teaching in schools.

Once we have WiFi support in place, MQTT libraries should work. I noted to check PubSubClient in particular.

The WiFi features currently has 45 votes.

Some progress update: managed to establish a connection to an open WiFi network within the simulation!

There's still much to be done, but this is one milestone :-)

Very ecouraging Wireshark screenshot !
Closer and closer to an MQTT message capture.

One packet at a time :)

Replying to @lzzy12's comments from another issue:

Does that mean we will be able to run webservers and run standard IOT simulations?

Yes, that's the plan.

MQTT works!

I managed to successfully connect to an MQTT server from within the simulation, send and receive messages, using MicroPython (+ umqttsimple):

HTTP works too. SSL does not - we'd need the hardware-accelerated AES peripheral.

Great !

I'm trying to connect to WiFi to test the pubsubclient library (https://github.com/knolleary/pubsubclient/tree/master/src), but I'm not able to connect (https://wokwi.com/arduino/projects/315894638733951554).

I think it's still in testing phase and not yet pushed to production

OK

Indeed - it will probably be in production in a few days. Meanwhile, I ran @pixavier's project, and it seems to work well in the testing environment:

Wow !
