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.
|
||
|
|
|
||
|
|
Circuit:
|
||
|
|
* Board with NINA module (Arduino MKR WiFi 1010, MKR VIDOR 4000 and UNO WiFi Rev.2)
