 for the circuit python parsec today I wanted to show you how you can scan a Wi-Fi network using an ESP32S2 based microcontroller right here you'll see I have a feather ESP32S2 and I have a little just a tiny little bit of code here that you can see that allows us to scan the networks so here's how the code works it imports Wi-Fi then we set up a little list called networks it's empty to start with then for network in Wi-Fi radio start scanning networks it appends the name to that little array then we stop scanning the networks we sort those based on the strength of the signal and then we print those out so here you can see when this runs my little antenna there just sniffed around and it found three SSIDs and it gives us our signal strength on those I think the strongest is the lowest number there and then it's done running I don't know if we'll get any different results if I kind of wave it up and in the air let's rerun that so I'm gonna hit control D whoops control D and run that and hey we picked up one more just by virtue of me holding that up a little bit higher so you can imagine you could bolt a little screen on there and have a little Wi-Fi SSID sniffer that's pretty portable maybe put a little battery on it and that's how easy it is to sniff for Wi-Fi networks using circuit Python and that's been your circuit Python parsec
