Hi,
Here is a little fun project; a WiFi scanner running on a ESP32-S3 + AtomVM + Erlang.
It works much like any other WiFi scanner where it draw “bell curves” representing the
found networks.
What may be a little extra fun is that it is making use of Apples (“secret”) geolocation service
to find out where you are, which then is shown on a map.
You’ll find it here:
Cheers, T.
