| 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 | ||
| This example is based on ScanNetworks | ||
