/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino model, check
the Technical Specs of your board at https://www.arduino.cc/en/Main/Products
This example code is in the public domain.

上のリンクのスケッチをそのまま流用した。
ネットをスキャンする標準的なスケッチ。
たぶん「#include <WiFiS3.h>」の部分をボードごとに変更すれば動作すると思われる。
/*
This example prints the board's MAC address, and
scans for available WiFi networks using the NINA module.
Every ten seconds, it scans again. It doesn't actually
connect to any network, so no encryption scheme is specified.
BSSID and WiFi channel are printed
Circuit:
* Board with NINA module (Arduino MKR WiFi 1010, MKR VIDOR 4000 and Uno WiFi Rev.2)
This example is based on ScanNetworks

ボードは、シリアルポートを使ってリセットして再接続しているが、ハードウェア状況によっては再接続が不可になることがある。 その場合、USBハブを追加してUSBハブ経由でボードを接続すると改善することがある。
